Entering the profession?--an unknown unknown. There are thousands in the sidelines w/o applications. Example: I was waiting in the USAFR, no FAA medical, so unknown to the civilian field. I got, what turned out to be a great move, got a physical suddenly a new pilot. Loads of guys and gals out there, make the T&Cs good enough and they appear. I know an AD we who wasn't interested in leaving, six months later a new hire at DL, now with 2,500 below him.
There's something like 14,000 jet corporate pilots, most are staying, but it could be a big source of pilots, if really needed. I know six former RJ captains that say they won't go back to 121, any bets?
