While at the station hospital, Naval Air Station, Lemoore, CA in 1964, i changed a leg cast for a Naval Aviator who had survived a fall in the high sierras. his chute didn't open and he landed in the snow and then bounced into a tree trunk which broke his leg. i remember thinking that he must be one of the luckiest people in the world. but then only a few months later, the poor guy was shot down and killed over North Vietnam.
There is another story of a man who survived a fall from a bomber over Germany during WWII. He also landed in a tree. He either had no parachute or it failed to open.
Oh my.
