Since there are many people here who enjoy building big planes such as bombers, I think it would be wonderful if we could have some kind of automatic Turret that finds and shoots at targets on it's own. Imagine all the epic dogfights one can have by attacking bomber formations like in WW2 whilst being shot at by multiple turrets like in the real thing.
The turret block thing should be customizable though, by speed, shape, accuracy and amount of guns, as to make it fit better with different builds.
