I had the privilege of getting to know Cliff Robertson a bit. He was chagrined by some of the technically inaccurate aviation stuff he had had to put up with - such as when throttles get pulled back to add power in "Always".

He was most proud of "J. W. Coop" - not an aviation film but decent. He produced it and flew his biplane for it - a Jungmann I think.

Borrowed it from Netflix years ago.
