It was a bit funny watching GSX pushback the DC-3. It's a tail dragger, so the truck went under the plane and hooked up to the real wheel. Incidentally, half the truck was inside the plane at that point... I'm not sure what the proper procedure for pushing back a taildragger, but GSX might do well for, if not realism, at least for practicality, to go around to the rear of the plane to connect to the tail wheel, and actually pull the plane out instead of pushing.
