I seem to be sitting somewhere between SFFP & Roadster here. In principle SFFP I suppose you are right, but I was thinking not so much about someone like me who has the usual aircrew back problems and high tone deafness that I can get along with, but more the poor sod who has come back from Afghanistan minus a few limbs and maybe some other bits. Once he's a civilian I still think he deserves a bit of preferential treatment, but maybe that's an emotional rather than a rational point of view.
Didn't know that about military hospitals Roadster, but as I never lived within 100 miles of one it would have been academic in my case.
