Parachutes catch a lot of air, creating a lot of drag. They can drastically slow a fall, allowing a softer landing. This slow drop, however, can be hard to control. A figure landing with a parachute might sway to the side during the fall.
Some parachutes trap air, just like a loose jacket can trap air on a bike ride. This trapped air wants to escape. It can often only escape at the edges, which makes those edges flap. Some parachutes have a hole in the center to release air in a controlled way. It makes the parachute more stable, with only a minimal change in drag.

Can send me this video please 🙏🥺
The hole is to prevent a collapse and drop the soldier as fast as possible to keep them from being a floating target.
That’s what I was thinking the whole time but it never said it I
Bro there's no point in making this john Steele just made a post explaining it in full detail
The holes just keep trapped air from leaking over the sides of the parachute, if that happens the chute will fold in on itself. The Mythbusters showed that when they tried to make a duct tape parachute.
@@8008es not everyone knows who john steele is??
Even if they’re a floating target it’s still a war crime to kill them while they’re parachuting
Shout out to the person falling that couldn't get their chute untangled
Struggle was serious
Saw that as well!! Was laughing my ass off!
More than likely he was fine. It's called line twists and isn't even considered a malfunction, just an inconvenience. It's like if you are sitting on a swing and spin yourself up. It's not tangled, just spun up. You can bicycle kick to get out, hence why you see his legs flailing around like crazy. Line twists can be dangerous if you are close to the ground or are under a high performance wing. Good eye spotting it.
@@funfromabove9728 plus it’s a roundie, not like anything happens when you flare on those things anyway 😂
Been there and done that, soldier did the right thing to kick in the opposite direction of the twist. Little trick I learned is instead of trying to pry the lines outward, it's easier to keep them closer together while kicking. Been in twists down to around 1500' before, definitely sketchy
I was a parachute rigger way back in the day. One of the reasons the Apex has the hole is it forces the air to a central point. Kind of like a funnel. It keeps the chute straight. The narrator is correct. At least for the round T-10c or the MC1-1 Parachutes. Civilian rectangle chutes work differently.
We call those ram air canopies. I'm happy to jump a 7 or 9 cell any day of the week, and truth be told those military t10s and t11s scare me every time I see footage of them 😂 thanks for paving the way though 😎
I was a rigger too brother! 6048mos USMC.
@@1980Baldeagle 92romeo army here.
Airborne !!!!
Just a regular old mortal over here. I appreciate you guys though. Thank you for putting it all on the line to help keep the rest of us safe.
I’m a current and qualified US Army parachute rigger. The purpose of the holes you see in the corners and on the sides of the parachutes is for steering and maneuverability. On the T-11 parachute(the square-ish parachute) has holes in it’s corners to allow a soldier to pull down on the chute, closing one of the holes to force more air out of the rest, which allows them to drift in a direction to avoid colliding with something. Others have holes to allow for better maneuverability. For instance, the MC-6(the dome parachute shown earlier in the video) has what’s called extended gores. There’s two lines the Paratrooper can use to maneuver the canopy to face a certain direction. They pull down on the line, closing the extended gore, and the parachute will rotate. It’s all about controlling the flow of air to the best of your ability.
Thank you.
RIGGER!!!!
Isn't it crazy how many comments in this thread make completely false claims with the utmost confidence? Thanks for your input. I'm a parachutist myself, but never jumped a round.
We thank you for your service
@@NickRobbins82 oh hell no that's fucked up👎
"they can drastically slow a fall allowing a softer landing" learned so much thanks 🙏
what
Lmaooo 🤣
And you got a like from the channel. That's the best part.
Aren't you being sarcastic? Why did you get a like lol
@@yous2244 exactly. 🤣🤣
This is how I drag my essays to 3000 words.
When a round parachute (used in static line jumps) does not have a hole on the top, the parachute tends to dump air uncontrollably. This causes the parachutist to swing like a pendulum. If the timing is such that parachutist reaches the ground when they are at the top of a swing they can slam hard and become injured. The hole at the apex allows air to escape controllably and ensures the parachutist lands on his/her feet
I thought that's why they fitted a peripheral hem.
@@onlybugwit I thought the ‘peripheral hem’ was to help prevent an inversion
This is why when I was making parachutes in a 6th grade class I put a hole in the middle not knowing that circle parachutes actually had them but I thought it’d make it more stable and it worked and it wouldn’t swing as my parachute before that would
@@onlybugwit Wow I am thinking this is straight out from the manual 🤯
Correct
Humans do speed up as they fall, but they eventually stop at a certain speed. You don't just speed up nonstop, you reach a terminal velocity
Exactly like a penny would most definitely hurt like a bitch if dropped from the empire State but it wouldn't yk kill someone
They accelerate until terminal velocity.
The hole in the apex isn't so much to stop oscillation, it's there to stop the apex from getting blown out when the canopy deploys. The canopy material is made from a porous nylon which allows air to pass through the canopy and stop it from spilling out the sides, thus causing oscillation. Modern round parachutes are typically made from zero porosity materials and will use mesh panes or corner vents to allow are to pass through and are far more efficient in stopping oscillation than porous materials.
Why didn't you just make the video
bro that one guy kicking in the air lmao
Man's ruck was not dropping
It's called "bicycle kicking ". It's done for untwisting the risers (straps connecting harness to suspension lines). Twists normally happen when bad posture exiting the aircraft. Been there done that
'SOME parachutes catch air'..??! I hope for anyone that's going to make use of a parachute that he is lucky enough to grab one that does!
glad you’re teaching us all this in preparation for WW3 drafting soon
😂
The force of gravity is consistent. You don't fall faster.
The t10d has a center hole, the mc6 parachute has channels to allow a jumper to control their direction, but those are only used in sof units, not ranger regiment though. Units like regiment, division and 173rd to name just a few, the mission set is airfield seizure and they want everyone to land as close together as possible, so the ability to make actual steering inputs is removed. The swaying you see with static line parachute, is caused by a weak exit. The free fall parachute has channels, that allow mff guys to fly the parachute for long distances. But they don't have a center hole like you'd see with a t10
Landings on these round chutes are really rough. Almost broke a leg on my second jump
They also make a great camp tent if there's trees. The holes on side would make a good door too. I grew up camping in my dads
imagine being a test subject for parachutes
He was just a rookie trooper and he surely shook with fright,
He checked off his equipment and made sure his pack was tight. He had to sit and listen to those awful engines roar. You ain’t gonna jump no more. Glory glory what a hell of a way die…
Thats not entirely true. When parachuting You do not continue to fall faster and faster. You reach terminal velocity (max speed a person/thing can fall).
32' per second squared!
@@brookeggleston9314 No. Terminal velocity is is a velociry, not acceleration.
My parachute backpack had a plate, knife and fork instead of a parachute.
Budget cutbacks. They didn't have enough fabric to make a whole parachute so they left out 10% around the hole.
The old dude who is flying without parachute is the legend
The hole is for when there's a parachute malfunction, it gives the parachutist an escape route.
Silly, they could get out through the gift shop. 😂
I saw the troop with the line twist. I bet he's grateful for the prior instruction right about then.
One of those videos where you know at the end of it, exactly as much as you knew in the beginning
I love how theirs one guy near to the end just literally walking on air while trying to untangle his parachute
The holes (release vents) give balanced drop, and are integral in directional controls for targeted landings...
I made jumps with a modified double L back in the day ! The two LL allowed me to steer the parachute.
what does that mean, LL / double L ?
“When a human falls to earth” - they generally make a mess if they don’t have a working parachute.
The reason for the slits in most parachutes is to make sure they open a full capacity and stay that way if just like a glass of beer if you overfill a parachute it's going to fill over on one side
“Man, that solider on the right is really struggling” (Calm voice continues)
😂😂
These kind of parachutes are more stable than the parachutes that do not have holes.
They’re called corner vents…and it certainly doesn’t slow you down much…lmao
Dude is riding the bike hard trying kick out outta those line twists!
If parachutes didn't have holes I'm sure they would lose an arm or a leg or the whole torso
The result would be a really hard whole body thud.
@@T-Dawg123a could kill them or else they wouldn't have holes and they would get to the ground closer.
And that is why there are so many broken legs using the Army parachutes.
That one dude squirming around lol
That one casual clip of 2 dudes successfully deploying the parachute while the last dude is like dangling from his harness...🤣
Did I see him drop his gear right before landing so he doesn't have to deal with that extra weight when his feet touch the ground? As a civilian, I had no idea they did this!
Yes, their legs have enough work to do to absorb the speed and weight of the body during landing, there is no need to add the gear weight on them, they can absorb their own impact.
It’s also probably an anchor
Ironically discovering this after enemy blowing holes in your chute
"The Earths gravitational pull accelerates a person faster and faster." is wrong because acceleration doesn't change much while falling. It mostly stays the same and the thing that rises is speed and not the acceleration. Acceleration doesn't mean how fast something's falling. It means how fast its speed changes.
Explained the reason for holes but didn't apply that to the military, just parachutes in general.
Shikimaru: What a drag.
It's so rare that parachute information videos are actually correct. Good work!
Thanks a lot!
"allowing us a softer landing" this.. this is an understatement.
Got a cousin. Retired 30 + years. 101 airborne. 200 + jumps. Retired a WW 04.
If my jump master heard the word hole he would say it's a modification and not a hole damnit. WW 2 had no modification and that's why they had the pendulum effect. Like a clock pendulum.
When I was a kid, a neighbour of mine told me about how he'd once watched a pilot coming down after baling out during WW2. He said the parachute was oscillating wildly, just as you describe.
Physics 101… the person isn’t accelerating faster. Acceleration is always 9.81… their velocity increases.
Soft landing. Lol. I was a dirt dart for a long time. Other than the camaraderie, jumping is what I missed the most when I got out. Some of my best life stories revolve around jumps and the guys I jumped with.
The old T-10 was a peach. Landings were always as light as a feather😂😂😂
Those parachutes look beautiful.
I remember this being one of the questions I asked when I was like 7 and to this day at 25 years old someone asks me why I know so many thing about such a wide variety of subjects I tell them, "I ask alot of questions" it is my life ambition is to learn as much as I can before I die. I guess its not a goal then since it does not have an actual end to it, but I seem alot happier then other people ny age.
Awesome..I'm 61and have the same philosophy on gaining knowledge thru life and my 21yr old son is following the same example..you can never learn too much..👍🤙✌️
@@rondias6625 God bless you and your son, all I can say is always be ready to teach, sounds like you didn't miss that lesson though.
I too live this life. If you don't learn something during the day, you've waisted your day.
Stay curious!
Like in any emergency slow it down, (me running from an alligator) “no”
"Parachutes are supposed to make as much drag as possible" Whoosh
The one dude was kicking an looked like he was freaking out lol
They really missed the opportunity to name reserve parachutes “sparachutes”.
Lil buddy was up there kicking and panicking...
So we just bout to ignore the dude flailing around in panic
Looked like ace Ventura diving in that blue jacket
"Line twist lime schwist"
Steering too. They’re more controllable and responsive
Is it not obvious that the hole is mainly meant to keep the chute from capsizing and collapsing?
First sentence completely wrong......the drag is perfectly balanced to get you to the ground quickly so you aren't a target hanging in the sky, but not so fast that you break everything.
They are not meant to create maximum drag they are meant to create optimal drag max drag would essentially be a very fast human kite on a windy day
Faster and faster. Learn about terminal velocity.
Thank youuuuuu fuckin hell
120 mph? I forget
Thank you!
Spot on. And it accelerates the body more slowly as time goes on. It's not like you accelerate past 9.8 m/s^2, then accelerate more quickly than that, then suddenly hit terminal velocity and stop accelerating.
This level of pettiness is only seen in KZhead comment sections for clips from the Real Housewives of Beverly Hills and weirdos wanting to critique military shorts. 🙄
You don’t keep falling faster and faster, you accelerate until you reach terminal velocity.
Or reach the ground. That tends to slow your acceleration very abruptly.
It's boyouncy. And the parachute is called an MC1-B. The hole is usually to the rear and they are used to give minor steering control when 'slipping'. 'All the way!'
They don’t create maximum drag, it’s a balance between not breaking your legs and not getting shot on the way down because you’re a slow target.
Lol plus you dont really wanna be floating like Mary Poppins while the enemy shoots at you
If it's not a MC-6, I'm not jumping it✊🏾💯
I jumped using a T-10 we had to use the risers lol
@@phillipgonzales4617 last time I jumped a T-10 was at Bragg in 2009. My brigade was the test unit for the T-11s and those are by far the worst chutes ever in my opinion.
Last time I jumped, I was under a Piglet 23.
@@phillipgonzales4617the old T10. A drogue chute for a dirt tart.
The guy struggling lmfao
There's something comical about the narrator remaining calm while that one jumper's lines are twisted asf
Who's that absolute Chad flying without a parachute and keeping his hands on his back pockets?
That's a stunt double from the opening of the James Bond film Moonraker. He's standing in for Roger Moore. He does of course have a parachute on really - it's hidden under his jacket. 🙂
My feet hurt just watching this video!
First guy to test it with a hole lol.
Some Navy Seals drop in with rectangular parachutes (gliding chutes) without a hole, depending on the situation ofc. Depending on the area and the mission, they might opt for low profile chutes to conceal their location and to land with more precision. They are much easier to control in direction.
Not only military chutes: ALL circular chutes have a hole. This allows air to escape non-turbulently giving an easier ride without penduluming the poor parachutist from side to side Some steerable aerofoil chutes don't need it
In 6th grade in a stem class I discovered this when we were making parachutes and I didn’t think about military parachutes I just thought that it would keep it more stable and it did and the parachute would go straight down instead of sliding off to the side again and again doing exactly what I intended
The hole is to keep the parachute vertical. Same reason civilian parachutes have them.
I've jumped half a dozen times it's such an amazing experience There's nothing else more thrilling and peaceful all at the same time
Weird question but did you have trouble breathing when your were skydiving? When I sit on a boat going fast or a motorcycle it’s very hard for me to breath.
@@jacobwade3625 no I didn't have any trouble breathing while under canopy I'm not sure I could breathe before it opened though lmao
I'm guessing the fact that the military will have to parachute in sub optimal weather and with more cumbersome gear makes this even more important to them. I mean the video doesn't answer why specifically the military.
Same reason hot air balloons have a Velcro top and a 500 ft rope that reaches the ground. We rip the top of the balloon out and it floats down slowly. We then catch it jump on the basket to prevent wind from dragging said balloon till we can ground the entire balloon.
“Some parachutes trap air...” while the guy on the right looks like his cords are wrapped around his head.

RIP Van... I haven't seen Millie in years, would love to see her, and ask about Ya'lls twins. You used to send her my way quite often. You were and still are one in a million, miss you Van🤍
Gravity is a theory. All that’s necessary for anything to fall is density and buoyancy...
Imagine you saw this outside your house....
Halo parachuting is another level
If you consistently have a hose running water into a cup, it will over flow, but if you put a hole in the bottom of the cup, the water will eventually balance out of you put a large enough hole. Same concept with a parachute
Ever since I've seen a video of a guy landing incorrectly on both of his legs straight, I feel very uncomfortable watching parachute videos ngl
My trapped air is about to escape
A person doesn't continue to build speed as the narrator says. They will reach a terminal velocity that is variable depending on drag and other things.
As a skydiver all im asking is why tf do these round canopies still exist and why they use them
I miss jumping…but my body doesn’t.
I was so expecting at the end, “by the way, with Ring, you are always home!”
Clint Eastwood said it best when he said that jumping out of a perfectly good aeroplane is not a natural act.
Neither is going 75mph down I95 in an air conditioned steel box, drinking coffee made from beans picked in africa and shipped across an ocean. But we do that…
The Mk-1 Paracommander has 26 holes 2 of which are large enough to step through.
Simple answer: stability ffs
So basically, it's like a funnel for air
