hhmm....i'll have to try that. i always go for the outter wing...i thought someone had said something about there being weakness there.
That actually is "a" weak area. If you take the wingtip off, the bomber is unflyable and it will crash. I'm not sure whether taking a wingtip off of a drone will cause it to fall out of formation or not (I don't think removing the elevators from a drone effects it enough to fall out of the formation, but if the pilot takes control of it, it's doomed).
Honestly though, shooting from a high position down into the "shoulder" area of the B24 sets it afire easily, and it's a guaranteed kill. And it's a larger target, and if you screw up your aim you may hit the cockpit for a quick kill too.
