So what's the stupidest way you've almost died?
One was when I was parachuting, and intended to land between two large trees. I had completely forgotten that between them was a third tree, equally large, that I couldn't see because I was directly above it. So I hit it (at about 70mph), stayed suspended for a moment while my parachute collapsed, then continued the 55ft to a very hard ground.
A very close shave was when I tried to land an aircraft in fog on a grass runway next to some trees, and realised just in time that I was actually headed for the trees. Another was when I took off in a plane that was too heavily laden and realised just as I lifted off that I wasn't going to clear the church steeple just ahead. I swerved past it about halfway up it. Another flying one was when I was flying through the Alps at night in dense cloud and the aircraft began icing up. That same flight ended when I managed to get to my destination airfield in England, but the engine quit through lack of fuel immediately after touch down and before I got to the aircraft parking space. Actually I have several more flying ones, like the two occasions when I nearly pancaked on top of another aircraft. Neither occasion was my fault, but that doesn't help a lot.
Or there was the time when I was motorcycling in the middle of the night in an English winter, and suddenly realised that I was on black ice. I was going at 140mph when the rear wheel started to overtake the front.
Or the time when I was practicing for a GS ski race in Austria, at some point made a silly but serious mistake, and ended up (according to witnesses) 50 feet in the air, somersaulting gracefully until I hit the ground, several times before I finally settled.
In diving I was at 109 metres on my CCR when suddenly the manual override valve for oxygen malfunctioned. I first knew about the problem when the high pO2 audible warning sounded at pO2 of 1.6, and in the very few seconds it took to come off the loop and onto OC and check my computers the pO2 had risen to 4.0.
None of these was especially enjoyable at the time, but they're all part of life's rich pageant!
