I've come to realize that this forum is for wish lists. So, the following isn't really a "suggestion" per se.
I've read that planes like the p38 and the a20 had modifications made to them whereby the lead plane in a flight had a level bombing sight in the nose (guns were removed, of course) which would signal the other planes in the flight to drop their bombs. This way you could take a bunch of nice dogfighters up, do a precision hihg-alt bombing run, then be right there for field CAP and general jabo cleanup. Of course the lead plane is a sitting duck, but I assume that plane would head for home after the drop.
