The seas are huge and empty. Keep in mind that this was just an experiment which could easily have gone wrong. You probably don't want to have to explain why you made a rocket-shaped hole in somebody's roof ;) Also: Chances are higher that you're able to recover useful wreckage (like data loggers) when you crash into water.
