British European are still sponsoring.
BC if you are willing to consider the discipline (the RAF are an undisciplined rabble anyway, but I won't go crab bashing here, where I'm out numbered
) then talk to an RAF doc (not sure who in the RAF - the RN it's the President of CAAMB, the Central Aviation and Admiralty Medical Board at HMS SULTAN in Gosport). My sister considered the RAF as a career. She had had a bad knee, but after 2 operations it was OK, and the RAF accepted once she proved she could keep up with the PT (by appearing at initial interview fitter than any of the Cranwell output!). She went for ground branch, but they might be OK in the air. Remember Douglas Bader became an ace despite complete lack of legs!
