I used to refer to the MoD Main Building as the 'Specialist Aircrew Recruiting Centre'. You just had to truss yourself up in suit and tie, spend time on the stifling underground before witnessing the shabbiness of the place and seeing all those poor $ods pandering to the 17:00-on-a-Friday whim of some VSO to realise that the minor embuggerances of a flying station were infinitely preferable!
So in 30 years, apart from 6 weeks of PVR porridge, I didn't have a single ground tour....
Unlike people-tube civvy flying, military flying is rarely boring or routine. I once flew over HQ STC at low level in one of HM's Bulldogs and saw the procession of people in raincoats trudging back up the hill from lunch in the Officers' Mess - the 'gabardine swine' staff officers, poor $ods. "You'll end up like one of those if you're stupid enough to be a career thruster", I told my student.
If you've been given the opportunity of a pilot slot at IOT, you really should grasp the challenge - you'll never get another bite at that cherry!
