Hi
I seem to know a lot about this subject so I'll enlighten you. To get in the RAF you musnt have it 4 years previous which unfourtunatly you do which starts of as a bit of a downer. I'm extremely sorry because I know how cruel it can be, but if you want you can ring the careers service and they might help you more.
If you think thats harsh try having an extremely small chance of pilot when you didnt even have an attack and a specialist says you dont have it which is my situation.
Good luck, try to get a second opinion from a specialist like I did and hopefully something coud prevail like the RN or AAC.
