Rather than rely on rumour, I would walk into the Army careers office and start the ball rolling again, beware of asking for advice there though as they are unlikely to "know" and will give opinion which may not be what you want to here.
AAC candidates I believe also attend OASC with the same selection procedures (ie same doctor) and they will know that you have been there before.
I would telephone OASC big chief doctor and ask for advice if I was in your situation. Remember that all RAF pilots are jet mates until proved otherwise, which is not the same for the AAC, so you may have a case.
Either way, best of luck, and keep at it until all doors are slammed in your face.
