[QUOTE="James Snover, post: 8258764, member: 67454"] There was one case in particular that had me thinking for a long time. The guy jumps, and his chute does not open correctly. It fouls int he lines, and only comes out as a streamer. It makes him start spinning, like a weight on a long string. The drag from the chute and the spinning effect slow him down a little, he's only falling 100mph or so, not at terminal velocity. He lands in a corn field. The corn was near ready for harvest, it wasas tall as it would get, and it was really thinck. The guy did not have a scratch on him. All the energy of his fall had been absorbed by the drag, the spinning, and the knocking over all the stalks of corn. I saw this on the Discovery channel, maybe ten years ago. Anyway, it got me thinking about air bags, and on a larger scale, impact barriers for out-of-control landings of aircraft. Instead of a giant pillow, what if you had a bunch of corn-stalk sized tubes that ran crosswise to the driver and passengers. Would that gve a softer impact to the occupant than the giant exploding pillow? But doing the math on it showed there wasn't really anything there to be gained. And for aircraft, even small light aircraft, I could never figure out how to make it affordable. Jim Snover [/QUOTE]
