But it didn’t work.. did it or there wouldn’t be a hole in the ground...or ocean, not trying to be pi$$yy but civil aircraft aren’t built for the stresses aerobatics place on airplanes, demonstrated by the failure of the control surfaces in your example
Flying an airplane inverted creates 1 negative g on the airframe in level flight. You should read the story of the FedEx crew who fought off a disgruntled s employee who tried to commit suicide by causing a DC 10 to crash. There were aileron rolls, hard pull-ups +g and push overs -g. I dont think that airplane ever flew in service again, but it held together.
