Back in the mid-'70s, ME training had been temporarily suspeneded. So all those who made it through to AFTS went through the Gnat/Hunter programme and thence to TWU Brawdy.
Great part of the world and real green camouflaged single seat jets to fly. Wonderful!
One day, after a slightly hard part of the course, our genial Flt Cdr was making himself a cup of coffee in the crewroom and remarked "Of course, if you lot find this all too difficult, you can always volunteer to go and fly b****y helicopters!".
It was obvious to most of us that this was a wind-up; however, a couple of wet tarts took him at his word and knocked on his door to announce that they found this TWU Hunter flying all too much, so they would like to volunteer for helicopters.....
Their feet didn't touch the ground and they were soon off the station. One became a navigator and the other something blunt.
Not that they were particularly missed.
