I was thinking if you were crashing into water and you jumped out that the plane would hit the water first
Gallileo says otherwise

It's not just about sky divers wearing flappy suits that slow them down. There are stories about air hostesses falling from planes and landing safely. They reckon if you pass out on the way down you've got a fair chance of survival because your body will be relaxed when you hit and that makes a huge difference. On that basis my choice would be "Break Out the Duty Free".
