Coming into the home stretch with the Navy, I can honestly say...
Yeah, what all the other guys are saying. If you truly want to fly, pick the first DOD component that offers you a spot for OCS/OTS and flight school. Study you a&& off, party hard with your crew, and work your tail off for the fitness reports/OERs that lead to choice flying assignments. Once you have the hours and are current, you can either punch or decide to keep going for the long haul. Be warned though. Staying for the long haul, at least in the Navy, means flying a desk at least once or twice and promoting out of the cockpit. (gotta love the retirement check at age 42 though)
Good luck, bubba!
