JC,
Hang in there - work out what you want - and determine the way you can best phrase it to defence recruiting to make it happen for both of you. Don't forget, unless you ace flight screening they're not going to come after you - its a big pool. Be proactive.
If your flight screening result wasnt good enough - move on. If its another factor, you just need to determine if you'll be a chance next round.
As per the previous advice, dont go blunt for frustration. They're good jobs, but you can talk to the f111 navs rerolling to pilot if you like, to see a real perspective.
To those at recruiting logging 12 hours for 3 hours of interviews,
Not the biggest sacrifice, and perhaps a glace at what its going to be like, every time you roll down to medical/pay section/the mess/dental for the next 15 years of your career!
