Yes, you can jump out of a plane and land in water and survive. However, there are certain things that you need to take into consideration before doing so. First, the water must be deep enough. If it is not deep enough, you will most likely hit the bottom and sustain serious injuries. Second, you need to make sure that you enter the water at the correct angle. If you enter the water at too shallow of an angle, you will again sustain serious injuries. Finally, once you have entered the water, you need to swim to the surface as quickly as possible in order to avoid any potential hazards that may be lurking underneath.
