I can look at some of my Commercial Pilot manuals for this. I recall seeing it on why an airplane flys, the flow of the air over the wings. I did not attempt to rationalize the physics at the time. Just hoped that the next time I did a loop, the wing would continue to fly through the loop. Ernest Nitka wrote: >B.D. - great question.
