Grand Slam Bomb

Summary
The Grand Slam bomb is a very advanced bomb that will appear in missions near the end of the game. It requires removal of the bomb bay doors and, contrary to what some think, is not an atom bomb, but simply a very powerful and hard hitting bomb.

Usage
Usage of the Grand Slam can be very tough. it requires the bomber to be flying level at high altitude, meaning you must have ascended to higher altitudes well in advance before approaching the target. When dropped correctly, a massive explosion capable of hitting multiple buildings will occur. When dropped from a medium or low altitude, or when not level at high altitude, it will explode like a normal bomb.
