If a pilot jumps from a plane over the Pacific Ocean without a parachute, say 40,000 feet, and lands vertically into the sea, what would happen?

If a pilot jumps from a plane over the Pacific Ocean without a parachute, say 40,000 feet, and lands vertically into the sea, what would happen? Will he be able to survive?

ANSWER:- First of all, if you don't have a protective gear, once thrown off the plane, you will be in -42 degree temperature and very low oxygen as well as very low air pressure. You will instantly feel hypoxia and will become unconscious and because of pressure difference, you may end up rupturing your body. Also -42 degrees without any protection could be outright killer.

Anyway assume that you survive that and drop down to 22000 ft, where air is breathable and you are actually conscious. Then you have some chance of survival. It's now the impact that will kill you and not the fall itself. You have about 2 minutes to the landing from 22000 feet. Instantly turn your chest towards ground and arch your body with hands and legs spread. With that you fill further reduce the speed of fall, now when you are about 300 to 500 ft from impact go full vertical and clinch you butt and cross your legs. If you hit the water any other angle, its like hitting concrete and you will be dead. If you go perfectly vertical, there is 2% chance that you will survive. But you also have to remember to instantly start moving your hand rapidly to reduce the speed of drowning. Remember water pressure double at every 30 ft or 10 meters. If you drown too much, you can simply die because of water pressure.It's a pretty safe bet that the extremely rapid deceleration upon entering the water will fatally scramble one's brains, and other organs, too. If you succeed to stay alive there, your last struggle is to have enough oxygen till you surface. If you manage to do that you should write a book :)
