Falling from an airplane is basically the same as falling from 1500 feet in terms of velocity. The highest dive ever is approximately 200 feet, and the list of injuries others have taken trying to match that figure is quite impressive. That suggests to me that the odds of surviving, no matter how practiced or proficient you are, would be very low over water. Of course, there are things you could do to improve your odds. Placing yourself near other people who might assist you would be a big one. If you could somehow make yourself float face up once unconscious that might help as well, although I struggle to see how you would do that given the colossal forces involved. Any kind of crush core would be a huge help. The horizontal component seems like a red herring when it comes to water. Any advantage you might get from the smaller vertical component would be totally overridden by the horrible death you would suffer due to damage to your internal organs.
