What a trash video. He basically says "um have they considered that you'll be going fast and that crashing is bad?"
He's not even consistent - he claims in one breath that any crash would breach the outer walls and that repressurization would be catastrophically fast, and in the next that humans couldn't possibly survive until the tube repressurized and would die nearly instantly from being exposed to vacuum.
He also doesn't really know how anything works and throws in meaningless stats constantly. Like when he compares the mass of the air in the tube about 20 minutes in - irrelevant to anything. It's like saying the water pressure in my shower is somehow increased by the mile of plumbing between me and the water tower.
