Well enlisted people can fly they just can't pilot, well it least they are not supposed to but i wonder if some enlisted personnel ever got bored* sometime and slipped a pilot 50 bucks or something.lol.
Don't know as I'm a grunt.But you need to check your facts. The Marine Corps and the Navy had enlisted aviators up until early 1941. Flying Sergeants and Flying Petty Officers. As did the RAAF, RAF, RCAF.
