I would, if you really mean what you say go full on for the RAF. I did and got a flying scholarship @ 16 and had 3 weeks learning to fly paid for by them and loved avery minute and hour. It has been one of my best experences to date (now 20 with CAA frozen ATPL\IR) through school and A-levels I pushed to go back @ 18 for direct entrance. It was my main goal. I always wanted to fly and I thought the military was the only place. You get the best training, facilities, instructors. When ur there ur an officer. The life style is second to none and in civi street is hard to top for the first few years of working. It has changed recently and the old boys have become disalusioned by it for sure but it is only for the person as they take and first experince it for themselves. It may not b for u, but u will never know unless u go c!
In other words for God sakes while u have the chance to go see DO! If they said 2 me tommorow come back it was a mistake I'd pack 2nite...
