"Guess what? After SDSR the RAF is short of aircrew, esp fast jet pilots.
I wouldn't necessarily agree with that; the RW world is hurting after the sustained Op Tempo and departure rates are ever growing. The ME world is down because of fleet extensions to C-130K, VC-10 and Tri* needing crews where there were none planned, on top of increase exit rates - it's only the state of the airlines preventing a total collapse.
I know of several FJ guys who can't find a seat right now and are stuck in desk jobs whilst the stream sorts itself out post-SDSR and Harrier's demise.
My personal view is that the "10 spare" aircrew wouldn't make any difference in the wider scheme of things.
