"skip bombing"
It's interesting to ponder the physics involved, and the game model. Aces High doesn't model water as if it was real water. It was like landing on gravel. But, then again, from the point of view of a bomb travelling at around 250mph, water is essentially solid.
Clearly Aces High models bomb collisions with the ground, and aircraft collisions as well. It also models ballistics, and ricochets, although the ricochets I have seen appear to travel in a straight line, without shell drop, until they hit something on the ground, or vanish into the air - but I could be wrong, the ricochets could be accurately modelled.
Skip bombing is essentially a ricochet, but with a very shallow ballistic trajectory. Perhaps the game could fudge the effect by giving the sea some of the properties of a tank's armour plate. At the very least it would be an amusing occasional one-off fluke bombing technique (in practice, no-one would bother).
Alternatively, and if Aces High *does* accurately model richochets, you could produce the effect of skip bombing by persuading a tank-driving friend to sit his tank in line with the target, and then coming in for a low-level bomb run, so that you drop your bomb on top of your friend's tank. The bomb will ricochet off, and hopefully hit the target, and you will have an incredible film you could post on YouTube - and after that, Hollywood! Or the talk shows.
