This happened again last night.
B-25H, about 25% fuel, no bombs, most 75mm gone, I lose my right wingtip. Nothing else. I cannot roll over to compensate, at all. Not full rudder, rudder+aileron, rudder+aileron+trim. I shut down my right engine to see if that would help, realized it was the wrong engine, so started it up and shut down the left engine, NOTHING would work. I was doing about 200mph, too, so I had decent speed for lift.
It was a rare lucky moment, I was able to nose up, get gear and flaps out and somehow touch down in the trees on my wheels.
I then spent 10 minutes taxiing to the nearby v-field to land safely.
Is this a bug?!?!?! Or is this just basically the B-25H pilots get screwed if they lose a wingtip?
