I've been in the Air Force for over 10 years now. I started out as a heavy aircraft mechanic. I worked on KC-10's and the E-3 AWACS. I got tired of fixing them and I cross trained! I'm now a flight engineer on the AWACS. I couldn't be happier with my job. Basically, I sit behind the co-pilot and monitor and run the aircraft systems like the engines, hydraulics, pressurization, fuel, weight and balance, etc. I handle in flight emergencies and plan the flight. I also smack the co-pilot in the back of the head when he/she says or does something stupid.
