How hard is it to survive a crash?

All this says again that airplanes are designed to cope with flight loads with the lightest structure possible, not with the earth or earth bound objects. Iv'e seen where aluminum structures turn into giant chopping machines or giant presses. No belts, straps or helmets are going to help. When I was working I had an assignment to design a 100 gallon potable water tank to be suspended in the overhead in a freighter. It had to sustain a 14G (I think) crash load to keep it from breaking lose and destroying things in front of it. One of the engineers with whom I was working asked why it had to sustain that much forward G. I told him that was the assignment and he said," That doesn't make any damn sense, everybody forward of that will be dead anyway at a 14G impact!"

I've noted how thin some of the aluminum is on the Cessna, thinking it's just razor blades waiting to be born.
