Yeah just looked it up and that’s exactly what I was thinking of! Aside from the obvious technical limitations and the part where you probably couldn’t teach average Joes to parachute reliably, I imagine the simple act of getting everyone to actually jump out of a plane is probably immeasurably difficult too. Like I know people who won’t even walk across certain bridges because their fear of heights just won’t allow it, getting someone like that to muster the courage to jump would be impossible.
