Why is the Boeing 737 still around? I know some of you think you know the answer, and that it has to do with type ratings and training costs. But what I’m asking here is something more fundamental: HOW is it even possible for the 737, a design dating back to the 1960s, to still be in production in 2024?
Stay tuned!

Hey Petter, great video as always, but regarding your sponsor betterhelp, they were found to sell their users data to other companies, while stating that their data would not be shared with anyone according to their privacy policy. That is pretty terrible considering their users were vulnerable to begin with. I'm sure there are a lot of good sponsors who would like to be featured in your videos. Edit: misspelled name.
Indeed bro I watched Mrwhoosetheboss and found it
Hate to break it to you, there isn't a single internet company that DOESN'T sell user data.
Fortunately he is also sponsored by incogni often enough to offset that 🤓
@@charlesmak534that is not true, and doesn’t change the fact that betterhelp violated their own privacy policy.
@@MADmosche It is most definitely true.
Old, retired flight attendant here. Worked on both the 727 and 737. My absolute favorite though: Bidding the galley position on the old DC-10. Down in the belly of the aircraft we could roll up our sleeves, crank up the ovens and the radio, ditch the high heels and put our sneakers on and send the trays up and down the food elevator. Oh man those were the days!
Just retired from Mother U. The Tens were still around when I was hired. I definitely remember hearing your opinion voiced MANY times by FA's back then. I sure did want to fly it but never got the chance. 9-11 really dicked up the industry.
"the food elevator" wtf
Good times 👍
The Lockheed L-1011 had a similar gallery downstairs also. My dad was TWA so I got to go in the cockpit at night (Oh, look at the lights...) as well. Different times.
@@tonyharvey2307The kitchens were below the passenger deck and you used an elevator to bring food upstairs.
As a Canadian, I’m still salty over how Boeing tried to kill the Cseries through regulatory strongarming and in essence forced Bombardier to sell out to Airbus.
And in return the A220 is going to terminate the B737 already seriously hurt bu the A320 family and stupid choices made by Boeing's management
I am too. They really just picked up all of McDonnell Douglas bad habits when the absorbed that company.
The UK government and Irish government also had a big hand in that pot. Gutted Bombardier had to sell to Airbus. The UK lost a lot of investment, but Ireland got *some* promised manufacturing business, but not as much. However, at least the C series lives. I love the A220, and also love the Embraer E-170-190 series, which seem to be hoovering up A220 orders that keep getting delayed.
And Bombardier with the Canadian government was no saint in their fight against Embraer.
Why? Do you not understand that to all US Corporates business is war, and your competitor is the enemy? The rules are just made to be exploited to your advantage, and todays allies are tomorrows enemies.
There’s an old FedEx 727 that flies out of KPTK often. Flight path and altitude take it slightly over a mile from my house and I always know it that one since it's twice as loud as any other aircraft leaving that airport.

As a flight attendant who is old enough to have started working on the 737 since the -200 days, my requirements of an aircraft are somewhat different than fuel economy and bypass ratios. For me the tiredness of this old old airframe is that with all versions up to and including the -800 Next Gen, the front lavatory toilet seat doesn't have room to stay upright because it doesn't' fit against the fuselage. The practical upshot of this is that we have an airframe that has been in service since 1967 where you have to hold the toilet seat up with one hand in order to pee. I cannot generate enthusiasm for this.
Having peed in a 737 front lav, I can confirm. Damned annoying.
sit down
It’s almost like this lavatory was designed by Germans
It also leaked into the EE bay. I think it was the APU Control Unit that everyone learned (very quickly) would stain your hands and shirt blue. It also, obviously, stank...
and as a ground handler i dont like that the ground power connecter is so high up, its higher up than on the a320, you have to hunch down to connect the air conditioner, compared to the a320 the cargo hold is alot more more cramped and you have to crawl inside when using a powerstow(though thats also the case on a220/e190)
The rough landings of the 737 make the 320 family shine in my opinion. However, flying onboard the 220 is wonderful!
'Rough landings'? I thought it was because Southwest had hired a former carrier pilot and he was trying for the three wire (passenger spinal impaction ratio:100-0)
Thanks, Petter! ❤ Long-time planespotter and aviation enthusiast here. My first flight was on a Finnair Caravelle and it was thrilling. The next on was on a PanAm 707 to NYC and it was also amazing and delightfully different from the first one. I got bitten by the aviation bug at 3 years old and my dearest childhood pastime was riding my bicycle to this "viewing spot" at the end of a runway (fenced off of course) and we'd spend hours watching planes land and take off. Asked my mom for a camera for my birthday. Got it! Probably used up a thousand rolls of film. Loved the 727, later 737, 757 , DC-9/ -10, Airbus 320 series, and of course all the prop planes and military jets! Now, many years later, I'm finally working in aviation sales & supply chain, basically selling and stocking airplane parts to airlines and MROs in Asia. This allows me to travel all over Asia to meet customers, get to know them, build and foster relationships with them, and observe their maintenance and repairs operations on Boeing, Airbus, Embraer, ATR, DHC and other amazing aircraft. As it turns out, many of them are AvGeeks too! 🎉 I honestly couldn't be happier now, finally working in something I'm actually profoundly passionate about, having tried my hand at several jobs, from HR to management in IT, lots of jobs over the years. I never felt excited waking up to a new day but instead hitting snooze on the alarm clock was practically a daily occurrence for 15 years. Sorry for the long post and thank you if you're still reading this. 🙏 Just wanted to share my bit and express my immense appreciation for aviators/educators like Petter - and all you wonderful people who love aviation! 🛫✈🪂🛩🛬 ❤
Its crazy how the 737 is 60 years old, 60 years before that was the Wright brother’s first flight
They sold progress to money
Technology progress is rapid during times of war. 2 World wars happened in that 60 year span.
The basic design is 60 years old but I'm pretty sure any newer versions are not.
What does that have to do with anything? 60 years before the flyer, Camillo Golgi was born. Crazy.
@@amarissimus29 You're clearly not the sharpest tool in the shed are you?
When Petter you point out that B737 has been in service for 56/7 years please remember that the Vickers Viscount, the first turboprop airliner, was in service for 56 years 1953-2009, which for an aircraft developed at that time was an incredible achievement. I flew them for BEA/BA 1970-1975 and later 1989-1990. Then B737
I would argue that the speed of advancement in technology, and the added complications of fly by wire systems mean the B737's 56 years is more like 70 when compared to the Vickers. Technology moves faster than ever.
production stopped in 1963...
Even the dc3 is still flying, but that’s besides the point. No other 60 year old airframe is still being built in commercial aviation
@@abreyuDHC-3’s made in the 50s are still flying and the DHC-6 just entered production 70 years later
They didn't build the Viscount as long as the 737 has been produced.
Hello Petter, Such an interesting history this 737 aircraft has. So many things can be said about it from many different angles. I retired on the 737NG fleet of 'my' airline and flew a selection of different types in operational life. I'd like to share my feeling towards/experience with it. To me, the 737 felt like 'a steam tractor in the skies'. Powerful machine with little suspension in gear or wings, giving a stiff ride. Found the NG more 'jumpy' in turbulence than the older versions. A very sturdy and reliable airplane. Watching cabin attendants go down on their knees to arm or disarm the slides gave an association with an era gone by and looked sort of strange, as if operating a museum aircraft. Its powerful engines saved the day a few times in severe shear and turbulence and I loved the power and reliability of these technological marvels. On this type I only experienced engine failures in the simulator which can not be said of some other brands/types I flew. I experienced the 737 as a demanding aircraft to fly in turbulent weather: especially the NG had a tendency to divert from its trimmed condition and needed small control inputs continuously in which it differed from other types like the 767. The type never let me down which may also be credit to the maintenance standards of the airline: apart from a few deactivated reversers, auto brake u/s and an IRS fault, only the coffee-makers broke down. Ceiing 41.000 on NG instead of 37.000 on the older ones often was helpful to stay just above some weather. Liked the 'old fashioned' overhead panel with all the toggle switches, it really felt like something from the past after visiting a 787 or A350 simulator. There will be a day when 737 production is over. Wish that Boeing may find inspiration, courage and funding to design a successor. Conclusion: my days on the 737 did not leave a romantic feeling or fond memories of a gorgeous looking airplane or one flying like 'a pilots dream'. As a workhorse however it was the most dependable type for me in many aspects. Great machine to get the job done. Thank you 737 🙂.
Glad you liked it. I thought that it was the worst jet at my airline and I flew most of the others, both Boeing and Bus. But to be fair, I am 6'3" and 220. It's got a MISERABLE cockpit. Getting your brain bag in and out of that thing was miserable. But that's no longer a concern with today's iPads. It has a tiny cramped cockpit. It's loud. Antiquated systems but with fancy avionics. It flies OK, but they all do so not really a ringing endorsement. No thanks. I bid off it as soon as I could.
Only in One T in Peter not 2
Once they worked out why the rudder was stuffing them into the ground, it was a good airplane for the purpose.
Peter, My pilot friend suggested that Boeing’s mistake was trying to fit engines that were ‘too large’ on a platform with such short landing gear. His recommendation was to use the 757 platform with taller landing gear. The 757 has the same cockpit and the engines would have fit perfect. Boeing’s choice to force fit the engines resulted in a compromise in safety as the engineering solution was non-optimum. With flying, you need a six-sigma solution and the safety compromises were their failure. They could have shortened the 757 to the size of the 757 and called it the 737 MAX, a perfect name for a taller, more impressive plane without the safety problems; and training would be similar.
The 37 and 57 cockpits are not the same. They require a completely different training program and have different Type Ratings. In other words, a 737 pilot cannot fly a 757 and vice versa. I once read that Boeing destroyed the jigs for the 57, so forget about that if true. The 757 is TOO NARROW for today's fat humans. Boeing needs to start from scratch and make something wider than the A320 (which is already wider than the 737) fuselage. Or, they can just keep putting out crap and let AirBus rule the airliner world.
@@lbowsk Which, after their lies to the FAA, is what they deserve.
@@lbowsk The 737 & 757 are totally different aircrafts, they just happen to have the same fuselage cross section.
I am well aware of that. The fuselage has got to go. I was replying to why the 757 is no longer an option for Boeing. @@markmiddione6423
I just don’t get why Boeing would build aircraft with such short landing gear and we saw that through the 707, 727, and the 737 Production lines and it just goes for show if they build the 797 anytime soon just pray they decide to put taller landing gear.
I would argue that the big “leap” in the 737 series’ development wasn’t between the 737 Classic and the 737 Next Generation series but between the original 737 and the 737 Classic series in the early 1980s since that’s when the design changed considerably, with the low-bypass engines being replaced with high-bypass ones. That gave the wing a whole new look and all the 737 variants since have basically been tweaks of the Classic (737-300/400/500) series.
100%. 737 300 was the biggest leap in efficiency of 737 development, reinforcing their dominance over my favorite manufacturer, Douglas (MD) in the early 80s, whereas, the NG was developed to 'stay in the game' v the A320 family
Absolutely correct.
Classic to NG was almost as big with an all-new wing and upgraded versions of the classic’s engines.
Absolutely. From the new biangular tail to the ovoid engines, the 737 Classic was the generation where a lot of the modern design philosophies of the 737 were first laid out.
They need to bring back the 757 and make it 3’ wider and 20’ longer. Put some giants under the wing and try and keep it under supersonic.
If it ain’t broke, down fix it. Oh wait….nevermind….
NAAAH 😭😭😭
more profitable :P
But that’s the problem they broke it
If it morphed to a CoffinJet, ground it, ditch it

Wow, and not a word about the fund managers that are now running Boeing and are using their legacy aircraft to squeeze out profit without actually doing what has been needed for a very long time. A brand new clean sheet design.
Agreed. Aerospace is a very slow payback model, development costs (investment) are huge and there’s often no return for at least five years from investment. Sure, the program will then run for twenty plus years and the spares and maintenance contracts are lucrative but today’s greed merchants want a quick profit. This is contrary to how the industry needs to operate.
100%. The last clean sheet was the 787, which began in the late '90s, almost 30 years ago. The accountants are just milking the system at this point.
A brand new clean sheet design would be untested at scale and be vulnerable to any unforeseen dangers, and all that to preform what the 737 already does anyway. The 737 at least has 70 years worth of testing and in the field data, everyone knows how long it'll take most parts to fail.
@@Edax_Royeaux what? So you're saying that a clean sheet design is more dangerous then trying to retrofit a 70 year-old aircraft with engines that don't fit? Are you saying that a composite aircraft isn't lighter and stronger than an aluminum one? Are you saying that engineers don't know how long it takes for components to fail? Do you think a clean sheet design means that every single thing that goes in there is a complete complete experiment? Are you saying it takes seventy years for us to know if it is safe? Basically, what the hell are you talking about? In case you didn't know the latest version of the 737 has crashed and killed more people per flight hour than just about any other aircraft made. So your argument is, let's keep doing that because it's safer? It's generally accepted and well known that the 737 passed its prime decades ago. That is one of the major criticisms of Boeing by both investors pilots and other industry types is that they need to stop trying to milk these legacy aircraft. In the next 5 to 10 years they're going to be totally noncompetitive.
@@InvertedFlight You appear to have jumped the gun on what was just 2 sentences I wrote. Don't know why you've decided to extrapolate about composite aircraft from all that, no wonder you're so confused.
I have fond memories of the 727. It was the first airplane I flew on as a kid. We used the rear stairs to deplane.
The 727 was/is a great plane. The Boeing 737 in all variants is as well. I don’t think most realize how good its service record still is.
I flew a Delta B727 and boarded from the ground. The belly was polished like a mirror, I could see myself beautifully in it. Hard to experience today.
yeah your parents, my grandparents, made great things. too bad you ruined them. too bad you ruined western civilization, completely. enjoy hell.
how did you get on the plane?
@@HaroldBrice We used the portable stairs at the side door (like usual, but no jet bridges).
My Grandfather was on the original design team at Boeing when they made the original design for the Boeing 737 100 .😊He was appalled at the MAX .
And that, says it all.
But grandfathers are appalled by everything.
@@marcmcreynolds2827 Mine not so much . He was a strong Scandinavian man who was not into other peoples drama. I spent my summers building Aircraft in his actual “Hanger” in the backyard in Kenora,Ontario. I am an expert on riveting and wiring single/double prop aircraft … I was paid in ice cream and McDonald’s. I then found out that my uncle got paid in cash so I asked Grandpa to increase my payment to 20 bucks,plus the ice cream and McDonald’s. He saw the MAX reveal and he said “ What in the hell is that ? Is that this 737 MAX ? It’s essentially a 757-767 mix and they actually have expanded the 737 -100 to 200 -400-600 and then they show us a plane that has zero real testing and my grandfather said they are going to kill people as that’s going to take many hours to retrain pilots with that engine placement their going to need pilots that fly still!”
The MAX is just PERFECT ! Boeing RULES !!!

I have to tell you that I thoroughly enjoy your content. You explain things so well and connect the dots as you walk us through your videos that your viewers always walk away learning something new. Excellent job and thank you to you and your production staff
Even the 1960s 737 is as you say a 1950s 707 fuselage section. It's basically been stretched and re-engined beyond its limit. We flew 72s on cargo runs into short dirt strips until the noughties. Tough wingspar, high clearance and powerful engines safe from FOD, plus rear airstair. Fabulous A/C.
the 727 is coming back............you heard it here, anon
@@HaroldBricesure wish the 757 was returning !!!
It's still in active passenger service with hawaiian airlines
How is it beyond its limits? It's still a reliable aircraft sells and performs well. Did you watch the video?
@mediocreman2 Great airplane. Terrible cockpit and ergonomics. Not good to accommodate the larger radius GTF engines.
Coming from an Information Technology viewpoint: why can you still see Windows XP, Windows 7, Windows 10 in use? Why, as a database administrator, I supported an Oracle 8.1.74 system years beyond the end of support? I know there are many companies that are running obsolete, non-supported software and hardware - there are banks and government agencies that have 1960’s mainframe COBOL applications still running There’s a certain amount of inertia, of “if it ain’t broke, why fix it?” mentality
they "fixed it" too much... a lot of ppl died because of this fixing...
While that is certainly a big factor, an even bigger one is the enormous cost of not only spinning up a new fleet type (training pilots, mechanics, spare parts inventories, etc) but especially fleet flexibility issues. When my airline began MAX operations, we still had a large fleet of Classics, which were in good shape, and paid for. Very cost effective, and we planned to keep them in operation for several years to come. The FAA insisted we segment the crews into NG/Classic and NG/MAX. IOW, not every pilot in the company could fly every airplane in the fleet. It represented such an enormous hit to operational flexibility it was literally cheaper to retire the Classic fleet years early. Imagine your IT crews not being allowed to use Windows 10 if they were checked out on Windows Chrome. The whole point of a single feet type for many LCCs is the operational flexibility it affords in terms of crews.
@@konpolski4765 I would argue that the fixes would have been fine if implemented differently. For the cost of an additional AoA sensor and a bit of actual training, no one would be talking about the MAX. Even as things have transpired, the fatal accident rate has been less than one per 900,000 flights.
@@achmedbincouscous2846 I agree with the excellent points you’ve made I wonder, though, if a commitment to a single fleet type could hamper a company - when the 737 comes up - the discussion often turns to Southwest Airlines, which has based their entire operation upon the 737, and has been a successful airline. I would think that Southwest going with Airbus would be an incredibly expensive and disruptive move - hopefully they are working with Boeing on a transition to a newer aircraft that would be not so disruptive
sure, and I remember my 1946 ford 1 and a half ton flatbed truck that I owned for many years.
Video very well formatted. Good comparisons' and clarity without going into too much detail. Thanks.
You glossed over the MCAS debacle which was the final fix for the need to mount newer, bigger (physical diameter), more efficient engines under the wing for the Max. With the standard design, these engines would not have sufficient ground clearance. This forced a redesign of the engine pylon, which resulted in the engine being located higher relative to the wing as well as being positioned further out in front of the wing. This provided enough ground clearance for the new engines. However , this resulted in new aerodynamics for the wing and new centers of gravity which necessitated the creation of the automated MCAS system to help keep the plane properly trimmed and balanced without pilot intervention. Which is not necessarily bad, except for the fact that the software was flawed, pilots weren't extensively trained on its new functions and the plane was only equipped with two Angle of Attack sensors (instead of three, one presumes, to save money). The software shortcomings were exacerbated when there were problems with the AOA sensors. Since there wasn't a third AOA sensor, if the two AOA's had different readings, there wasn't a third AOA to function as a tie breaker to give the software the correct AOA reading. This resulted in the MCAS creating wild interactions with the flight controls, trying to correct perceived, but incorrect issues with the AOA of the plane. The software then overrode pilot inputs, and ultimately crashed two Max's. I'd say that going through these design and software machinations were a strong indicator that it was time for a brand new, clean sheet, airplane.
Well said, any new redesign or features would increase the production and operating cost of this aircraft. Boeing compromised safety for profits
@@SacrificeBreedsSuccess To me that's overly simplistic thinking. Did DAC compromise safety for profits when they made a DC-9-80 from a DC-9-50? (still cost a billion 1980 dollars BTW, just for things related to that stretch). Always starting over with a new design is another way to compromise safety, vs well-proven designs, systems and parts. And it costs everyone money: The airframer who is constrained on how much they can charge; The airline which pays somewhat more up front plus needs a lot more parts inventory and staff training... and finally the passenger. A variant/stretch can be just fine if it's done just fine. Boeing's failure was they did it too much on the cheap (AoA sensors/software, training). Even MCAS was ok in its original incarnation: One push and done. But then it got pressed into service to do more. All said and done, fatal MAX accidents have been less than one per 900,000 flights. A throwback to safety numbers from earlier decades, but hardly a "death trap".
@15:22 He literally says, "Now, the full story of how Boeing was pushed to develop the 737 MAX instead of designing something entirely new is a quite fantastic one and it involves some really clever backroom politics between Boeing, several involved airlines and Airbus. Now, I will tell you more about that in a coming episode, .."
@@seanLeprechaun if you’re trying to tell a story about why the 737 may not have a future and you leave out the MCAS debacle and the deaths of hundreds of people because of that “upgrade,” then you haven’t told one of the most compelling issues that drives the future of the 737. Putting content like that in another video isn’t right, unless you’re just trying to generate more views. Accidents and deaths due to poor management decisions, engineering and potentially profit driven priorities can’t be left to another video.
@@roch145 I agree completely. I was already familiar with the MCAS issue and the peculiar placement of the 737 MAX's engines. This video's total avoidance of the subject, for whatever reason, felt akin to gaslighting. Sort of like watching a documentary on the U.S. Civil War that never mentions slavery.
DB Cooper loved the practicality of the engineering design of integrated airstairs.
...then he slammed into the ground.
And then he died. None of the dollar bills he received ever turned up again and the FBI knew the serial numbers. He probably froze to death in a thundercloud
@@BigTyltprobablt
"Cooper" jumped from a B727. Does the 737 even have rear air stairs?
Therefore the Cooper vane. en.wikipedia.org/wiki/Cooper_vane
Since it is based on the 707, which is itself just a derivative of the 367-80 which first flew in 1954, the 737 system design is 70 years old. The 707, 727, and 737 all have the same basic dual control system. Oh, you got there. What the 737 lacks is modern systems, like the triple redundant systems on every Boeing since the 747. Boeing had to get the law changed to allow them to certify the MAX 7 and 10 without EICAS.
I see a bit of the same issues with the Boeing Starliner and the SpaceX Crew Dragon. Boeing makes everything "traditional", complicated and then all the faults creep in, cost overruns, groundings etc.
Question is, if EASA will play along with it.
The US way of grandfathering in old stuff should stop. Make State of the Art the rule
This whole event is completely contrived. We always see Order Out of Chaos. Create some fake chaos and then they already have the solution, 'Order', ready to go. This is a PR exercise to justify government funding for a new clean sheet aircraft. Boeing just can't compete with the Airbus A320 family, so need to build a clean sheet plane. They need the chaos to justify asking for funds, as will likely get it. The public will back it as they now see the 737 in bad light.
So you think the 737 max still uses equipment from 70 years ago? Different engines, different flight, controls, different cockpit, you’d probably have to work to find pieces that match the original aircraft.
I was born in 1962. My father drove the Ford Consul in my youth. The 737 max is the equivalent of a ford Consul with airbags, abs and electronic ignition strapped on.
any chance that you could support your statement with objective facts?
I see nothing wrong with that. After all, Porsche introduced the 911 in 1964, and it's still in production, with _all_ the modern safety and performance upgrades!

Back then: we need a solution to 727 shortcomings. Engineers whipped up a new plane in 3 years. Today: we need a new plane. Nah, we'll just put a bigger engine to it. But it'll take at least 5 years to figure it out though.
And the those old engineers did it all on paper and checked their math with slide rules.
@@Begeye-bh5ux Yep, and with DIE policies average IQ people are being replaced with lower IQ people.
I’m guessing the regulations are a tad different…
@@skenzyme81 to be fair the process of getting it all certified likely was much easier and faster. And there is so much electronics now in the machines (safety, fuel efficiency. Electronic fixes of design problems) that they all have to be certified as well.
This is what happens when you have management-led projects (today) versus engineer-led projects (1960s).
We've come along ways. First airliner I flew on was a DC-3. No Jetways at the time. You walked out unto the tarmac and they had a footstool to help you enter the aircraft. But plenty of room and the seats were very comfortable.
What was your reaction to seeing something as gargantuan as the 747 fly for the first time?
scruffy, which rest home do you live in? congratulations
DC3 and 747 are favorite
@@petergriffin8796When the Concorde (British version) started flying, they did a promotional tour around the country. We went to the airport to see it land. It was something to see. They let one of our 747 pilots fly the left seat. The news media interview him and one of them asked "what's the difference between flying a 747 and the Concorde? He replied. About as much difference of driving a Greyhound bus and a Ferrari? Back in 1990, we took a trip to Australia. We flew Qantas on a 747. We left LA at 10 pm Sunday night. 18 hour flight. It wasn't crowded at all. Since it was at night, the stewardess brought us some pillows and we occupied the middle row and raised the arm rests on the seats and laid down and went to sleep. When we woke up, we were about an hour from Sidney and it was 6 am Tuesday morning. Never done that before. LOL
@@HaroldBrice Not there yet. The plan is to wear out instead of rust out.
I loved the history lesson. I'd to see more videos on engines over the years too. Thanks so much!
The variations in lifespan among various aircraft are fascinating. My father's squadron in the US Navy flew the F7U Cutlass...a disaster of a plane. Meanwhile, the US Airforce is putting new engines on the venerable B-52 and expects many more years out of the airframe. Some families have three generations of B-52 pilots.
This is my grandad’s B-52. My dad replaced the engines and I replaced the airframe.
@@gbcb8853 The engines are being replaced again.
the thing with the B52 is that if they were all grounded tomorrow, they wouldn't be replaced. They fly because they're already flying and if they weren't flying there's no compelling mission requirement that mandates an equivalent be created to replace it
@@miscbits6399 The B-52's compelling mission requirement is its uniquely high boom-for-buck ratio. ;) Of course, if one sought to craft a clean-sheet design to optimize for that particular mission requirement in 2024, it would look nothing like a B-52 and probably wouldn't even be a single manned aircraft.
I fly on the P8s and its a mix between a 737-800 and 737-900 and it uses the room in the baggage compartment for extra tanks! Its a pretty cool airplane and looks cool with harpoons on the wings. Very good safety record as well, we have flown them thousands of hours with no injuries. The only one recently went off the runway was pilot error and nobody was iniured. I personally have flown over 1200 hours on the P8 and the only emergency I experienced was a minor pressurization problem, which didnt even cause discomfort because we landed as soon as we noticed. I think it is the best of the 737 technology before they switch over to the max which was poorly executed.
RCAF is buying P8s and it sounds like they will show up before the.first F35.
@@realalbertan yes, we showed them through one of our squadrons P8s.
@@engineernels1057 I listened to the defence minister being interviewed about Bombardier wanting to bid and he rightly said they didn't have a ready to go product. Not only that but could you not put the pilots through a 737 training pipeline before they arrive? Or run them on a US P8 course? So much easier to get going.
@@engineernels1057 also heard we're getting Block 4 F35A modified with the F35C refueling probe, I'm assuming Australia has that same modification since we both had Hornets previously.
@@realalbertan yes that's what other countries do, the put them through the same training course we go through in VP30.
100% agreed. I've been intrigued by aviation since I was a kid and currently hitting 20 years at an airline. You hit on every single point that I've told others about the 737s and 757s. I've seen the A220 and agreed that it is the one aircraft that will be nipping at the 37s heals. Embraer 195 E2 appears to be struggling to get sales as I've only seen them being used for startup airlines or low cost regionals. So feel Airbus has that under control.
"snipping at the 37s heals"? You mean nipping at the heels. Sheesh...
@@RSole9999 yep. Nipping 😄
British airways have been using Embraers for at last fifteen years. start up?
I like the "Airbus A320neo" blue-print poster thingy in the background - especially in the context if the video's topic... 🙂 Is that always there (in other videos)?
I remember many of those 727 "Whisperjets" at the Atlanta Airport if my youth. The DC9 was prolific there too.
Dc9 have a really short range.
@matsv201 True. It was one of the first common commuter jets.
727s are awesome jets, but they are anything but "whisper" quiet.
The only difference is the 737 was designed in a different time it was designed for old airport equipment where all the airbus aircraft were designed for the modern airports so the most efficient engines will fit without un-natural engine installation
@@RCAvhstape The 727 launched with turbofan engines which were noticeable quieter than the turbojet engines of the original 707 and DC-8. Of course from a modern perspective they were not exactly a whisper. The MD-80 series used basically the same engine, and until they were finally retired a couple of years ago you could always tell when an MD-88 was flying over, they could easily be as loud as a 777.
The Boeing 737 line really ended with the NG. Moving the engines changed how the aircraft handled and sloppy design of opaque flight automation systems to hide the new handling characteristics caused two hull losses with no survivors. The stall avoidance feature was designed on the premise that the system never received bad data from the captain's Angle of Attack sensor. If someone had asked what happened when the AoA sensor was stuck at a high value, the stall avoidance feature would have included a limit on the maximum applied nose down trim to less than pilot command authority with the first installation. Even with the fix, the 737MAX still has the problem that it becomes a significantly different aircraft to fly if the horizontal stabilizer trim drive fails. Hindsight is 20/20, but Boeing would have been much better off if it ate the $1 million per plane penalty and airline pilots transitioning to the MAX had simulator training sessions to avoid stalling and familiarize themselves with the different pitch response to changes in power. The lack of an 'automatic' mode for the 737MAX engine deicing system, combined with the MAX engine cowling unable to withstand the heat of the deicing system, outside of icing conditions, has forced further delays in certifying the MAX7 and MAX10. The open fan concept suffered from the mass of the gearbox needed to get the two open fans to counter rotate. Replacing the fixed vanes of the turbine section with a drum that spun in the opposite direction of the turbine spool could work, if some way to keep the two sections spinning at opposite but equal speeds relative to the airframe was found. Eddy current braking of the faster component might work as flow through the turbine would try to maintain a constant speed difference between the two sections, so slowing down the faster section would speed up the slower section, but even a no contact braking system will generate heat that must be dissipated.
The debate over simulator sessions had absolutely NOTHING to do with MCAS. The discussion of simulator sessions was due to added features of the Roll Command Alerting System (RCAS) which would provide pilot notification and direction for upset conditions and the Runway Situation Awareness Tool (RSAT) which was an aid to pilots to avoid runway overrun situations. Both RCAS and RSAT were new safety features that Boeing had developed to improve safety as a result of reviewing the database of accidents and incidents.
@@jeffberner8206 Both crashes were the result of the 737MAX being able to enter a stall in conditions that were outside the stall conditions of the 737NG (above a certain angle of attack, aerodynamic drag on the MAX's engines would go from pitching the nose down to pitching the nose up, potentially into a stall). Absent an MCAS, pilots transitioning to the MAX would need simulator training to recognize and avoid the new stall condition, so Boeing self-certified that the MCAS automatically applying nose down horizontal stabilizer trim if the angle of attack was above a certain value removed the need to train pilots to recognize and avoid the stall.
Great and informative video, as usual! I too find the 757 to be a nice looking airplane...except on the ground. Those spindly, gangly teenager-like legs are almost comical. And now I'm thinking to buy some shares of Boeing while they are cheap to see what they can do over the next decade or two. Despite the turmoil, I always have faith in them. Maybe it's the wing pins the airlines used to give us kids back in the day, and stabbing myself with those things and bleeding on the seats made me a sentimental fool for venerable old Boeing. They haven't let me down (uneasily) yet! Keep the quality content coming!
The first airplane I flew on was a 727 back when TWA was a major airline, that was in 1978. I had the opportunity to fly in an old 707 too. Flew in a number of 737's as well.
Always awesome to see peter praising the awesome 757 😊

@@HaroldBrice Yes but wife's come and go, more often go these days but Allah is forever.
I haven't really understood the love for the 757. I've flown on 757s a few times (passenger/enthusiast here, not a pilot), and didn't really care for it. To be fair, though, I think that's because the plane was quite old, with the vinyl on the seats cracking, the interior still smelling vaguely of cigarette smoke, and the plastic lenses over the lights yellowing with age. (This was in 2001, long after smoking was banned in planes in the US!). United Airlines. I did fly in a 757 operated by Icelandair, and its interior was in much better shape.
Peter , this was an Excellent episode, really informative Thank you. At age 52 and working in Aviation 34 years I know a lot about the 737 family. Yet still I learned more from your Video - Thanks Again Paul
One thing I think you missed out on, and is very important, especially for Boeing aircraft, is Grandfather rights. If Boeing want to up grade a model, they only have to certify the new parts to current standard. The rest of the aircraft is assumed to still be certified. Makes it a lot cheaper to up design a model.
Note: the fuselage cross sections of 727 and 737 are not the same. The lower cargo compartment is larger in the 727.
The problem with Boeing is the same as other US companies that are listed on the stock exchange. They hired CEO whose only priority is to protect the interest of shareholders. Meaning they will cut headcount to save labor cost to boost share price. They retrench many QC inspectors that are suppose to ensure the quality of the plane build at Boeing. That is the reason why the quality of Boeing Max drop. My first company is Seagate that also have a CEO, who behave like Boeing CEO. He will retrench staff to cut cost to boost share price. This affected quality of the product and cause the company to be in a bad shape. After Seagate was bought over by an investment group. the new owner delisted Seagate from the stock exchange and want the new CEO to focus on the core business. The new CEO improve quality of the product instead of worry about the share price of the company. The company that focus on the core business will improve the quality of the final product.
From a basic factory workers perspective, that type of management makes life hell for the base level employees. I work in a JIT automotive supplier and we have a lot of issues at the plant where I work..., short takt times, rushing to make numbers, having to do the work of two people, 12 hour shifts, 60+ hour work weeks, high turnover rates. If Boeing has similar issues, I can see why they would have defective aircraft.
Petter, one of the main reasons holidayairlines like Transavia are gradually fasing out their 737-8 fleet and replace them with Airbus A320neo's and 321neo's, is because of the noise the current engines produce. I myself live directly under the approachroute of runway 06 of Schiphol. Planes come over at approx 1200 meter, and especially the noise of 737ceo's is deafening. When I compare them to more modern types, the Airbus 320family are far more bearable. Still noisy, but way less noisy than the 737's. Since airplanenoise is THE major cause of complaints from people living around Schiphol, I feel that your video has neglected this aspect of the plane and why airlines are on course to run the 737's out.
My experience: CFM-56 equipped 737s had been flying their downwind leg over my house for some time when one day a louder/shriller sound had me running outside to see I thought might be a 707 making an emergency landing. That was my introduction to the CFM-56 on an A320. Maybe their C-weighted sound level looks fine, but the overall effect was in a different category than the 737, at least to these ears. Perhaps the engine mount isolation or something?
Move - get new camp ⛺️
Does a lot of the noise from descending airliners on final approach or at least in a late leg come from the control surfaces and flaps/slats/ landing gear turbulence ? (rather than engine noise)
@@davidpowell3347 Nope. When they come over my house I hear the engines spooling back, which results in a deafening noise. Typical sound, without looking on FR24 I can tell it is a 737-8. It is a low thunderous noise. Flaps, slats make a higherpitched sound.
Not funny. @@bobwilson758
Thank you for making all these great videos. You are a well of knowledge. Love it.
Nice to meet you. Where can I see a sample of the 1967 B737 video?
I remember those back stairs on some planes when i was younger, not sure what planes they were exactly, but i clearly remember an exit out the back of the plane, i could look out a little window into the stairs compartment while i was waiting for the bathroom lol
In early 80's I was fairly late for my flight in Helsinki and was whisked off to the plane straight from check-in. ( This was before "security" was invented.) Everybody else was already on board when I entered from the back. Felt like a VIP for sure. This was probably the high point of my life..
Back in the 2000's, I was on a short flight between Philadelphia and Reagan National. When we left the terminal building, we were bussed to a small turbopropplane, and embarked through - indeed - backstairs. Back then I wasn't interested in types of planes, so I couldn't tell what kind of plane it was at all.
@@velisvideos6208 Somewhere in the 2000's, I had a transfer in Chicago. Coming from Seattle and flying to Amsterdam. The pilot on arriving in Chicago told us the local time. When I transferred - had been waiting at least two hours - I got into the plane, only to realize I was the very last passenger to get in. Right after me the door closed. Then I realized the pilot on the previous plane HAD TOLD US THE WRONG LOCAL TIME. He was ONE HOUR off.
@@Dirk-van-den-Berg I think "D.B.Cooper" put paid to the rear stairs... he pulled off that stunt twice.
@@awuma Twice?
From what I remember, the Sud Aviation Caravelle was the first of the twin tailmounted engine airliners for short and medium routes. She had her first flight in 1955, followed by the BAC 1-11 in 1963. The DC-9 came in 1965. All of them had a similar rear airstair as the B727 and were relatively low to allow loading to be done manually.
Indeed, exactly.
There was a bunch of rear-engined Soviet airliners of that era, too. Apart from engines disintegratiing and taking out the other engines plus flight controls, they were tough birds.
@@awuma Yes, the Tu-134, first flight 1963 a nd the Tu-154, first flight 1968, but both needed external stairs, at least bthey did not have airstairs in the back. Then there was the little Yak-40 (today it would be classed as a small regional jet), first flight 1966, and the larger Yak-42, first flight 1972, which both had rear stairs. All came long after the Caravelle, the BAC 1-11 and the DC-9.
The Caravelle (first flight in 1955) was indeed a very innovative aircraft establishing many standards for jet airliners that are still used today. It is also, in many ways, the ancestor of what will become Airbus.
Don’t forget the Boeing 717, Boeings version of the DC9.
Wow! this video covers half of the aviation history..though mentioned the name of each brand-maker, it brings how each design develops to what is now. Unfortunately, some things are not according to what they expect to happen. I enjoyed how this video is challenging the whole aviation industry and manufacturer to get even better.
The Western B737-200s had built in "air stairs" that extended out of the forward section of the fuselage so that passengers could easily deplane without a "jetway bridge".
That's a pretty good run for an aircraft that was built on compromises. I flew on a 787 a few months ago. It is in a whole different class from the 737.
I've flown on a few 787s recently. On my last flight on one, (Air Canada) the whole cabin interior shook/wobbled around as we took off and landed (all the overhead bins were visually shaking above our heads) and some of the tinted windows had already gone discoloured (brown). The 777 I had on the return journey felt like a much better built plane. A bit disappointing TBH.
Yep while old isnt necessarily bad there are definite advantages in flying inside something built within the same Century you are in.
787 is a beautiful plane agreed. 😊
So what happens if Airbus keeps working on the A320 and Boeing is not motivated to discontinue the B737?
@@aycc-nbh7289 They go broke.

That's a Canadian designed aircraft .
happy to see the it in the hands of Airbus….
@@sokolum If I recall it got there due to a trade dispute spearheaded by a complaint from Boeing. The result was Bombardier ended up with the deal with Airbus. I had heard and I think it was on Mentor Pilot that at one time Boeing could have gotten the plane. Going to be interesting to see how this all plays out with the 220 taking sales from 320 and 737. Boeing is in a corner with the 777X delays, Max issues killing some sales, Max 7/10 delays plus the writing on the wall that they need a 737 replacement by mid-2030’s so they got to start right now.
Having flown on the A220 a lot (Swiss), I can attest that it’s a gorgeous plane to be a passenger on. You do wonder if Airbus will try to go through an avionics change to ensure it’s a full family member.
Great storytelling! This is some of the best content on the internet.
In the '70's I grew up under one of the approaches to Chicago O'Hare (32L I think?) and I could identify every type of airliner that flew over. Even back then I was curious why the 737's had such long skinny engines. Now I know! Thanks!
Growing up and living in Alaska all my life, I have great respect for the mighty 737. Overall it has proven to be a rugged and efficient aircraft that has operated in some of the most rugged flying conditions geography and economics has thrown at any aircraft design. I remember a crabbed up landing at Deadhorse on a frozen airstrip where Alaska Airlines had to cancel the day before because of 80 mph winds and whiteout conditions. The next day when we landed it was still blowing pretty hard and the pilot masterfully landed in a stiff crosswind. So stiff that looking out my window in front of the wing I could see the runway lights layed out at maybe a 15 degree angle to the length of the aircraft. Crabbed into the wind until right at touch down, the pilot straightened the plane to touch on parallel with the centerline. Many, many fond memories over the years flying in, around, and in and out of Alaska on 737's. Boeing or "Boing" as my (former P51 pilot), father used to say, will bounce back. Oh Dad used to call Alaska Airlines, "Elastic Airlines" for the same reason. Anchorage, Alaska
Awesome Dad jokes.
"elastic airlines" never met him, but i love your dad
They just need to get rid of the Douglas accountants and hire their engineering managers back
@@jimsteinway695 Doesn't it get tiring to beat that old dead horse called McDD? Aside from being ridiculously over-exaggerated, it glosses over the fact that those intrepid engineering managers were the ones who pooh-poohed the awkward startup across the Atlantic and their cheap, no frills first product suitably named "bus," and even after it began selling like hot cakes; they scoffed at the fly-by-wire technology on the next platform too, until they woke up one day and found they had allowed the scruffy startup to grow up and catch up and become an equal competitor that was now eating Boeing's lunch. The lamenting about McDD corrupting Boeing doesn't say much about the resilience of the old Boeing if they capitulated so easily and a quarter century later are still pining for the glory days. Yes, McDD had developed some pretty bad habits, from working with the U.S. armed services during the Cold War, but much of that ended with the Cold War. The one thing truly corrosive that McDD had was a union that would cut off its nose to spite its face. Just say NO to ANY thing management proposed, seemed to be its unwavering philosophy, until the Cold War ended and they suddenly saw the demise of the company as a distinct possibility, then they began to cooperate, but it was too late. Still, that old nature of the union seems to be the biggest thing that infected Boeing and lingers. The engineers of old perhaps weren't pushed very hard to focus on costs together with safety, but its 25+ years later and by now they should have learned that engineering is defined as: The application of scientific and mathematical principles to practical ends such as the design, manufacture, and operation of efficient and ECONOMICAL structures, machines, processes, and systems. Whining about management being focused on costs is stupid, no one said it had to be in lieu of safety. I know Boeing employees take great pride in pithy sayings such as: Quality, Cost, Schedule… pick any two. Why?!! A competent person will strive to balance all three. The same with safety. It doesn't have to come in lieu of efficiency or cost. The biggest cultural change needs to come at the rank and file level. Other Seattleites didn't give them the nickname "Lazy B" for no reason.
I'm relatively new subscriber. I find myself anticipating episodes. Not only is content superb, you're very excellent at presenting. Youve got the charm sir. . Terrific show
14:06 just a couple of weeks ago, I sat in a presentation from the former chief engineer of the PW open fan design. Man, if we can get past the problems (noise and rotor failure complications) that engine will be a game changer, especially in the fuel efficiency area (imagine an engine with turboprop efficiency but turbofan speed).
Great video as always, but also as a person who struggles with mental health thank you for speaking so openly and normally about it ❤ Also I'm very thankful for this perspective since earlier I only heard of Boeing being cheap and reusing their old designs after the merger with McDonnel Douglas

That is crazy
In my opinion, Boeing has 2 options going forward. 1.) To either recycle the 757 body and develop the 757 max to compete with the a220 (if streched), a320/ a321xlr. 2.) To develop a clean sheet design aircraft (possibly the 797) to replace the 737.
Not only that, but since you cannot carve up a 787 body to make a freighter, and with the demise of the 747, will the 777 become the next freighter?
Amazing and very complex info explained in a very good manner and process. This shows why you are an Instructor. I would like to see the equivalent in the Military world about the B52 and its journey. Not quite your cup of tea, but maybe someone in the comments could pick up on it?
As a 20 year old Indonesian Avgeek, The Boeing 737 Classic is the aircraft that started my first ever experience flown onboard an airplane when i was a kid at about 16 years ago. Few years later, i started to learn about the Boeing 737 and it turns out the 737 has many tragic accidents especially The Rudder Hardover Saga. With that saga is over, i am confident the 737 is the best and most popular aircraft in the world. But in October 2018, the table's turn. March 2019 however is the final blow for Boeing. January 2024, everyone is again trying to avoid the Boeing 737 MAX and i am curious wanted to experience my first ride onboard the MAX. Time will tell.
I have watched many of your videos and must say you're the best! You make me watch the entire video by presentation alone.
Perfect video telling the true story behind the Renton 12’ 4” diameter fuselage that links the 707, 727, and 737. The 757 was also 12’ 4” diameter and also built at Renton, but had significant design changes that differentiated from its predecessors
Did you know that the 757's aft fuselage extends lower than the front because the 757 started out as an updated 727 and continued using that 727 aft fuselage (even after they decided to give 757 767 commonalities). It extends lower to make a space for the fuel lines to the 727 aft engines that the 757 does not have.
Great commentary thank you!
If the blended wing body ever comes out it will put an end to the body wing configuration because they are from what I understand 30 plus percent more efficient.
De havilland Mosquito?
The big problem with the blended wing/body design is that it would not be compatible with airport gate equipment, specifically the boarding bridge. Boeing had an interesting design concept for a twin aisle replacement for the 737. I don't know what became of that.
Boeing should have bought the CSeries program and use it to replace 737Max and start the NMA program to compete with A321.
True. It is past its sell by date- but money is the main thing at Boeing these days. They could, and should, have built a new jet to compete with the 320 Neo- and absolutely everyone knows it. The Max was a cludge.
Great presentation, thank you.
It was so nice to see a Braniff 727 in one of the shots. My dad flew for Braniff for about 30 years through every comeback they attempted and was running the 747 program when they finally shut down in Dallas. I know the pilots LOVED flying the 727 for its performance. All I really remember from that period was flying non-rev, getting bumped a lot in the mid-70's, and the smell of stale cigarette smoke baked into the fabric of the seats in the cabin. LOL. But it WAS a good plane. ;)
Petter, I love your videos, and your insightful observations about aviation matters. Your use of English is remarkable for a non-native speaker. There's one quirk I've noticed in a few of your videos, and it's "who" versus "which". Basically, it's "who" for humans (and pets) and "which" (or "that") for all other objects. There is some wiggle room, but saying "the engine who they chose" definitely sounds odd. I'm guessing that Swedish doesn't have this feature. I'm also hoping you will take this feedback in the spirit it's intended in. Keep up the good work!
I've pointed this out before, and he still says "who".
@guinnog2 I thought he was German but living in Spain.
@scotthutchens1556 No, I believe he is Swedish. Similar languages though. This distinction doesn't exist in German either, which is why I made the guess that's why he does this.
@@guinnog2 Thanks! After reading his bio on his website I did see that. You swear he was German though. Haha.
Hey, I am a staunch defender of the English language, so every time Petter says "descending down" I scream at my screen "as opposed to decending up?"
Quality issue... like Italian sports cars of the '80: nice design, good performance that get you quickly to the next garage.
Great video! I do you have a couple of questions though. You said the original 737 already started with compromises in the first place. Have you covered what those compromises were in a previous video? You also said that no more variance beyond the max - 10 would be developed due to regulatory constraints. What are those constraints please?
Well one question would be what we mean by “compete.” It is not as if old designs stop actually flying. A DC-3 for example will still fly today, nearly a century after its development.
It will however be hard to convince any airline driven by efficiency (be it fuel, pilot time or crew time) to actually buy and use them 🙂
Reminds me of another one of my favourite "aging" jokes: old golfers never die... they just lose their balls!
Typos in the titles look REALLY WTF - interesting video, as usual.
I fly 2 days a week from Seattle to San Diego. Since January I switched from Alaska to Delta First Class. At first I was skeptical about the A220. Now I love the Aircraft. At least up front the plane is quiet, efficient and bright. Unlike the A321 that Alaska inherited from Virgin America, the Delta A220 galley seems large enough to serve 4 different hot meals. The interior that Delta uses seems very nice. So I suppose I am hopeful that eventually Boeing will ditch the 737 (I do like the Max 9) and develop an answer to the A220.
Does the A220 have the full size overhead luggage lockers that the MAX has?
@@awumaThe luggage lockers on the A220 are absolutely fantastic. They are so big that they swallow my maximum size roll-on bag on its side wheels first.
Really Excellent Video - - thorough and interesting. Thank you !
It sucks seeing this unfold. So many of my friends parents growing up were Boeing employees and they were so proud of their aircraft. They worked at the 747 plant in Everett though. I do remember on a school sponsored summer trip we flew on a 757 and a chaperone sitting next to me was gushing about what a great aircraft it was.
It’s just incredible how many amazing commercial aircraft came out in the 1960s and how quickly each went from drafting table to commercial service. Meanwhile in modern times it takes nearly 3 decades.
one word: boomers.
I'm a boomer who rubbed elbows with participants in those quick-turnaround designs. One word: Overtime (, mandatory).
@@marcmcreynolds2827 yeah, sure thing buddy. now tell me how you invented the jet engine before you forget your own name.
@@theregnarute I sat at my desk (mostly), doing my humble piece of the effort. But doing it as well as I could, and calling out anything that came up in meetings which might compromise safety. I sense from non-engineer phrasing like "yeah sure thing buddy" that you've done absolutely nothing, which would explain why all of this goes right past you. But at least you can roam comments sections, looking for people to insult. Better than nothing, if you're into that sort of thing.
I think the regulatory design oversight and certification is vastly more stringent than it was in the 50's and 60's, when we knew so much less and aircraft were much simpler. There were horrendous flaws in many of those early airliners, even the B737 with its rudder hydraulics. The gradual relaxation of FAA oversight at Boeing has had disastrous consequences.
3:50 no, the reason for the 727 having its engines where they were is because that's where they were placed by Hawker Siddely on the Trident. Apparently on early 727s some of the parts were stamped HAWKER SIDDELY as Boeing forgot to erase the designer's markings. The British aviation industry wasn't just infiltrated by Russians stealing designs for Concordski. We also 'shared' a lot of data with our American "friends and allies."
One of your very best analyses. Excellent Petter.
It seems to me issues are not so much stuff falling off, rudders jamming, or aircraft spinning out if control. Its more to do with not enough space under wings for the engines, dated construction technology and outdated control systems for contemporary lower skilled flight crews (not every pilot is a graduate test pilot).
Before watching this I always thought the 737 was a bit of a Triggers Broom, and that the Max series bore no resemblance to the 737-100. Thanks for the comprehensive and clear explanations 😊
Alright Dave
I flew in the 737 when I was in the Army back in 1970. I also flew extensively in the 727 around that time.
Yeah, you and Dan Cooper, haha
Was that 737 flight between Honolulu and Vietnam? I'm not even sure if the 737s could fly that far.
At 1:39 - 1:43 into the video - What is that extension off of the rudder. Is it a static charge release mechanism? St. Elmo's "fire-fighter?"
Thank you enjoyed this article very much. I am far from an avionics expert, but I have flown in most of the aircraft mentioned here. The 737-800 and 320 non-neo more times I cared to mention, but two aircraft stood out for me: the first times I flew in an a350 and a220 (only last month to Zurich from LCY) - they were so ..... quiet. I was next to the wing on both occasions and couldn't hear a thing. As a child of the 60s, I grew up with the 737 and would be say to see them (eventually) disappear from the skies, but that's progress for you .... I agree with Mentour in that we should celebrate one of the most successful chapters in aviation history and it would be a shame to see its reputation unrestored.
As you've mentioned, the engine is the most important part of an aircraft's design. Shoe-horning ever larger engines into the 737 is increasing difficult, and I don't think there's any way they could get a larger engine on it. The evidence shows that higher and higher bypass ratios are the course of engine development, which guarantees the engine diameter is to be larger. I think it will be this inability to use the most efficient engines that will close out the 737, perhaps before 2030.
Common sense tells you that a bigger engine means more ground clearance. Boing thought they could get away with it by not extending the length of the undercarriage. That was their downfall. People died. They fudged it and should pay the consequences. This iteration has been a complete disaster. I will never fly in any 737 max.
Absolutely. And disappointing that Peter doesn't discuss this, But then, he's a Boeing guy.@@trevorthomas2373
Of all the bad decisions Boeing has ever made, not buying the C-Series program when they had the chance is certainly the dumbest. What an irony it would be if that program is going to put the final nail into the 737's coffin - or into Boeing's.
I can definitely say of the jets I've been aboard the 757 seems to take off and climb harder as a passenger than the others I've been aboard including the md80, the 737, the 767, the MD11, and the KC135(military tanker 707) so I can definitely back the claim it has good power
I must say, that not watching your videos for a while, you’ve made a huge progress. Not just your content and visual, but also the delivery, vocabulary, phraseology… you sound like a native speaker. Yes, you have a faint accent but even that is way less noticeable than before. 👌
Interesting video. Boeing made a mistake in taking Bombardier to court. They should have instead worked with them to acquire/produce the C series, ending up with a new more modern design than the max. But hindsight has 20/20 vision.
Boeing did a lot of mistakes like moving HQ, playing games with Embraer instead of fixing core business, etc
The Bomardier issue was snatching defeat from the jaws of victory. And of course it was done under the same CEO that was also responsible for the MCAS fiasco.
They should have a yank back golden parachute rider when it can be proven CEOs helped sink a company instead of leaving it better (whispers) _merely to get the parachute._
Petter, Nolinor Air in Canada operates 47 year old (!) Boeing 737-200 classics equipped with gravel kits on some of their more remote airfields connecting mining towns. That gives you an idea of the reliability and quality of the build of Boeing in the 70s. With all the recent quality control issues Boeing is going through, can anyone say with any degree of confidence that the present day 737 Maxes will be flying in 4.7 years much less 47 years?
Thank you. Now I have to fly to Canada and try to get on this plane
It still boggles my mind the places they take those kitted-out 737s. 👍
It will. Have 6000 orders been canceled?
Rather like Land Rovers - good design, well built, sturdy materials, relatively straightforward maintenance..... they go on and on.
@@federicoprice2687 737s and Boeing are the things to hate right now in our internet pop culture world. Boeing needs to straighten out their mess and fire the mechanics who left the nuts and bolts out of the door plug. In fact they should post their names so they can receive the proper scorn or be placed in a hall of shame somewhere.
Kudos to your presentation.Legend.
As always Peter, your videos are absolutely fantastic!!
Question to MentourNow pilot about aircraft operations: when in Europe, with Air France for example, they use containers to load luggage in the A/C belly of planes of the A320 family. When I look at Delta, it always use baggage handlers to put baggage in and out of the plane. Why such differences in aircraft operations?
Minimum wage is a lot higher in France than the US. Baggage handlers are cheap in the US, not so much in France. In all industries cheap labour discourages automation.
Apparently the A320 will take standard size baggage containers while the 737 (7" narrower cabin) won't. I suspect this means that in the US (where the 737 predominates) airports just aren't set up to use baggage containers even if Delta would like to use them. And as kenoliver says, baggage handlers in the US are cheap so nobody wants to invest in containers.
The C-130 Hercules has a Buildcounter of "only" 1/5th of the 737 but this Bird was first build in 1954 and is build in a row up to now. The Cessna 172 "Skyhawk" was first produced one year later and there were more Skyhawks build than any Boeings and Airbus and Lockheed combined. So the 737 is old, no question, but Aviation, Winegrowers and Whiskeylovers know: Old didnt have to be bad. Quite the opposite is true.
Excellent content, fascinating, thanks
