(1). I was in NROTC and went to OCS for 6 weeks.
(2). Flown the T-34/TA-4/F-4/F-18/F-18D. Currently assigned (reserves) to VMFT-401 in Yuma and fly the F-5.
(3). As far as getting the airframe you want, there are two factors: (1). Your grades and (2). The Needs of the Marine Corps. I had average grades, and had it not been for a jet draft when I went through...I would certainly have been flying phrogs. Usually, everyone wants jets and there are a couple two/three jet slots per class. Everything is situationally dependent. If you want anything bad enough, you study hard. Best advice I can give you is to keep it in your pants at P-cola/Meridien and keep your dollar bills off the wall/ceiling of Molly's. Instead keep your nose in the books.
(4). "Stick skills" become kind of second nature. The faster the aircraft goes, the more important it is to think on your feet and stay ahead of the game. It takes a while to completely master the aircraft.
(5). I have been on a LHD (USS Wasp) and LHA (USS Belleau Wood). I was also on the Saratoga. Have been stationed at MCAS Beaufort, 29Palms, and Okinawa. I was also assigned to 2/7 as a FAC.
(6). Yuma is very nice to fly in. Living isn't too bad either.
(7). Best advice I can give you now is to get in shape for OCS. Worry about OCS first. Nothing else. Don't go to OCS with the attitude that you are going to be an aviator or you'll be home before you know it. It's not easy wading through the Quigley in November or running the Ocourse with shin splints that hurt like hell. OCS is not easy, and it is not uncommon to see 3/4 of the people fall by the wayside. Then you go through 6 months of the dolldrums at TBS....don't worry about flight school there, either. Once you make it through TBS (late next summer) then start worrying about flight school. Just do the best you can at each stage, and you will find it to be very rewarding.
