>>1770466the real problem with high speed collisions aren't the impact but the secondary organ damage that occurs because inertia. You might be able to save your body with a big soft cushion but if you slow down too fast, that action will cause your organs to crash against each other, like your brain will crash against its skull. Now a plane at cruising speed of 660mph that's accelerating even faster because freefall + gravity = you're going to need a lot of time to slow down that momentum or your organs will just explode upon impact even with soft cushioning
