Best way to survive is to never jump out of a perfectly good airplane! 20yrs ago was talked into skydiving by a buddy who does it 150+ a year. Was going to jump that Friday. Buddy did it for a living, filming people as they jump. His business partner on Wednesday was in a big accident. He jumped and his main chute and reserve did not open. He hit the ground and did not die. Unfortunately he survived. EVERYTHING that you have 2 or more of, he does not now! He has 3 toes, an eye, 4 good fingers, a kidney, half of his liver and intestines, a testicle, no teeth. Took almost 2yrs rehab for him to be able to leave hospital. I took it as a sign from GOD not to do stupid stuff like jump out of good airplanes!
