I would be happy if water effects are realistic as much as possible. I mean all sorts of stuff, but especially when aircraft crashes into it, not just some splash into water. Aircraft crashes into water when plane is falling into it in smaller angles (around 10 to maybe 30 degrees) are spectacular, not some fall into water like a rock. It would be really impressing for players and also good for advertisement clips, I think ;) . And also low-altitude flights above water, when the water is being trowed aside by the force of engine exhausts, but not just some simple effect on the top of water like in any other game. It would be fantastic. And I am not quite sure but I heard somewhere that if some jet flights too low above water, it can suck it into engines and it can cause crash or damage it, didn't it?
