Haha, just tried the U-2, what a great plane! Practised convoy busting and as the plane was so darn slow, I just decided to switch the time fuse to 10sec, land just infront of the convoy, turn my plane around, drop the bombs and take off.
I wonder if you can fly it if you lose both of the top wings? One of the convoys, shot them off my plane, but unfortunately didnt get back into the air as my pilot got killed.
