ORIGINAL: geofflambert Hope we find out who the hero was who tried to rescue the pilot. I can't do it now but as a boy scout I learned how to dive from a floating position down (I don't remember, 12', 15'?) to some milk jugs full of sand on the bottom and bring them back up. The plane was in 20' of water, I couldn't have made it, I don't think. Apparently the canopy was ajar a bit, possibly indicating the pilot was trying to get out. Would it have been wise, knowing you were going in, to open the canopy completely before hitting the water? They tell us if we accidentally drive into a lake or river to crack open the driver and passenger windows, wait for the water to rise up to your chin, take a deep breath, then open your door after the car is full, as you wouldn't be able to do so until the car fills. Yes , opening and locking the canopy might have been a good idea. Old time carrier pilots used to do take-offs with the canopy open and locked. Part of the problem with holding your breath then hitting the water is the "gasp principal". They teach it in Navy DWEST (Deep Water Survival Training) is that you should take several deep breaths , and saturate your lungs. As soon as you hit the water , the cold is going to cause you to GASP , losing any air you have in the lungs (and probably inhale a mouth full of water). It's so pronounced that HELO crews actually fly with a HEED bottle (sort of like a small SCUBA divers pony tank) to give them enough air to get to the surface (mainly because helos ALWAYS turn upside down , as opposed to fixed wing that only occasionally turn turtle). One of the hardest things about getting out of a sunken aircraft is getting out of your harness. Unless you regularly practice , the shock of the crash often makes it impossible , especially if upside down.
