I've seen a combat plane hit in a mid-air, and half the rubber bands holding the wing on broke...and the wing flipped to the SIDE of the fuselage!!! The rudder now became the elevator and the elevator the rudder!!! The pilot was able to continue flying and land safely with no problems! Another example is the planes made of gutterpipe. The tails are mounted 1 1/4" off center for simplicity, and it has no effect on flight performance.
