Right, I'll jump in before the grammer taliban come and attack your spelling/grammar!
Have a good look through the 'OASC Wannabes' thread at the top of the Military Aircrew Forum, and do a search in that thread and see what results you get - it's all in there.
In the mean time, while the RAF reject the vast majority of people with a history of asthma, I believe the AAC and the RN look at everyone seperately on a case-by-case basis.
Cue Airborne_Artist to try and recruit you into the Navy.
Hope that helps,
