As a blunty who is 1" shorter than you, I have had some chats about this stuff. If I am correct, all RAF Pilots work towards Fast Jet. If your thigh bones are 'in proportion' to the rest of you, you'd remove those knees on ejection. I also think you'd have trouble on fitting into anything else really. I know I had some squeeze in a Bulldog and can't have a 'back seat ride' on anything with a bang seat.
The flying world is dominated by munchkins. If you want some blunt views about life on the ground, PM me. Rather not air too many views in such exalted Master Race company here!
