'Cause, maybe they realise that Big Bro is starting to recruit again, and, using history as a learning tool (because they have JUST got up to strength with pilot numbers for the first time since the late 90's thanks to the new LOM) they don't want to be caught short AGAIN!
Or having to explain to those on high why a newly aquired SAAB is on the ground and not flying.......because there weren't enuf pilots!!
