Interesting to note that naval aviators, USN & USMC, made up a slim majority of pilots in the AVG.
As an aside, my father was an Ensign and a pilot in VF-42 on USS Ranger when the AVG recruiters came around. He, a USN regular, had no interest, but some USNR reservists, having served to near the end of their commitment with only rumors of prospects in sight, were interested. I know for certain that among those to go from the Ranger Air Group were Noel Bacon and John G Bright (VF-41); John Armstrong (VF-42); Allan B Christman, David Hill, and Edward Rector (VS-41); John Petach and Peter Wright (VS-42). Armstrong was killed, Bacon went back to the Navy, Bright went to the AAF, Christman was killed, Hill went to the AAF, Petach was killed, Rector went to the AAF, and Wright went to civil aviation.
