Mythbusters also did an episode where they compared dropping (dead) pigs onto concrete and dropping pigs on to water, from a height where they reached terminal velocity comparable to a humans. Both pigs were Very Dead. IIRC, the pig dropped into water was slightly less Very Dead, but it was still Very Dead. They weren't actively guiding themselves to land feet first but I wouldn't expect much out of that.
Water could be a component of a survival plan (e.g., "my partially deployed parachute is slowing me down enough to make this the equivalent of a high dive"), but "just land in water" is not a survival plan on its on from terminal velocity.
