My aircraft from time to time so piloted? (2,6)
I believe the answer is:
by george
'my' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for by george that I've seen before include "Goodness" , "Well I never" , "the dragon was killed" , "exclamation of astonishment" , "planes might be flown thus?" .)
