Could you survive a fall into water....
Discussion
Hmm, whilst I know that the posted document probably contains all the info I need to enhance my chances of a deep water fall survival, I'm too lazy to read it. I wonder if I'll ever regret this moment.
Incidentally, I'm surprised that feet first is the way to go - I'm sure I saw a documentary on South American cliff divers and one of them was spouting on about you had to enter head first as doing it feet first resulted in dislocated hips/legs/other bad things.
Might have been b
ks though.

Anyone who has sky-dived (sky-dove?) should have an answer to this one.
It should be noted that one would probably accelerate at 10 m/s/s. So, by 10 seconds out of the plane one should have reached the accepted terminal velocity which is, I think, 120 miles an hour.
The acceleration isn't constant, so you'd need to solve a differential equation to find the time taken to reach terminal velocity.Anyone who has sky-dived (sky-dove?) should have an answer to this one.

Feet first, make as small a profile as possible before impact. Still going to end up with broken bones but you might survive.
Hit the water at 120mph, which is about as slow as you can go as a sky diver, and you may as well be hitting concrete. Literally, definitively, your legs would shatter into a hundred pieces, and most of the pieces would end up inside your abdomen, a nanosecond before that burst like a balloon.My aircraft break-up survival plan (and we've all done this) would be to try and 'track' (as we skydivers call it) across the sky sideways, then 'stall' out, and stop, just above the water, effectively dropping a harmless few dozen feet from the stall point.
In reality I'd misjudge it and hit the water flying sideways at 200mph.
Tracking is where you fall in a normal skydiving arch, then slowly swing your arms back behind you and straighten your legs, like a swing wing plane. Speeds over 200mph are easily attained, at about a 45 degree trajectory.

Holy thread ressurection!
RE braking the water tension with something...Doesnt work. Mythbusters tried and even from only 30 meters or so you still end up horribly injured or dead.

Yeah but that was 3 pages in!! This is PH and my time is precious so I only read half the fist post and then jump to the last page.Fume troll said:
Flying home last night from Stavanger to Aberdeen, there was a moment when I could smell burning. Turned out to be the cabin crew burning something in the galley... but it got me wondering.
Lets imagine you're flying at sufficient height (above the sea) to achieve terminal velocity. Lets say 10,000 ft for the sake of it. You fall or jump out of the plane.
What's your survival stragegy? Try to land on your back? Or go in feet first, legs crosseed, covering your face with your hands? Try and slow yourself with clothing or a seat cover or something?
Think I read about someone who fell out of a Russian plane into a swamp and survived...

Was in Stavanger not too long ago. Spent most of my time running boaty noobs out in the FRC in the little harbour there, (quite picturesque), and out into the Fjordy bits. Was great fun!Lets imagine you're flying at sufficient height (above the sea) to achieve terminal velocity. Lets say 10,000 ft for the sake of it. You fall or jump out of the plane.

OK lets assume like Jimmy Pak in "Rendezvous with Rama" that we have survived a fall from height into the cyclindrical sea with our tee shirt held above our heads as a makeshift stabaliser/very small parachute. We entered feet first in an arrow profile and didn't die.
What would get you within about 10 seconds to 10 minutes in the North sea would be the freezing cold.
My dad had a real aversion to the cold sea and so do I, he could go into the sea but within 5 seconds would be back out again virtually comatose on the beach retching suffering from hypothermia/cold shock. It took a few goes before he learnt not to go in!
I can swim well but put me in cold water and I'd be flapping about on the beach with the black curtains descending within 5 seconds. Body just can't stand it. Genetic?

I believe hitting water at that speed is like hitting concrete, however I'd be trying to go in feet (toes) first.
damn it...I'd say the only hope is to try to enter the water feet/toes first and hope for the best, but I'd be a monumental impact - the contents of your arse would likely be flushed right back up to where they entered.
