I repeat my point that BALPA should now take up the cudgels on behalf of all its members and ensure that everyone of them should have an equal opportunity to be considered in such a scheme should they so wish.
Really not going to happen. You are grasping at straws if you think the MOD will consider anyone without previous.
Most pilots l know would not be able to pass army basic training. I could not run 1.5 miles in 10 min 30 now. I could do the CFT with 25kg and do 8 miles in under 2 hours. Not sure what the RAF one is but certainly less arduous.
