The Continental off runway excursion here in Colorado suggested to me that one should only remove coat and shoes (if you do that sort of thing) on an airliner after reaching cruise altitude.
After suddenly finding yourself outside in the dark, the wind and the snow after a botched takeoff you'd certainly want your coat and boots.

Same with a water landing.

Great choice for place to put the plane and great execution. If the pilot looks old and has lots of gray hairs - THAT'S A GOOD THING!
