Was the Well-Shaft of the Great Pyramid a backdoor?

The Great Pyramid of Giza is filled with unique features that add to the mystery of its design. A long, narrow passageway known as the ‘well-shaft’ connects the upper chambers and corridors to the bottom of a deep excavation beneath the pyramid.
The original purpose for the Well-Shaft is a topic of controversy, and many researchers use it as a ‘get-out-of-jail-free’ card for design theories that would otherwise not make sense.
One of the most popular explanations for the Well-Shaft is how the Great Pyramid was originally sealed by workers escaping through it, and also that it was a point of entry for early looters from Antiquity.
This video explores the design and functionality of the Well-Shaft, and puts the theory of a ‘sneaky back-door’ to the test.
