I seem to remember a RAF Wessex tasked to lift a Portacabin up a hill in Ireland for the Army, having worked it all out they figured with a reduced fuel load the lift was on, just.
Portacabin was all rigged and ready to go, on the day off the lift they tried and couldn't shift it, landing on they found the RSM or whatever, had thought.... hmmm if the RAF are shifting this for us, they could also take this this and this, so had filled the said Portacabin to the roof with furniture....
Remember the 72 Sqn Christmas Tree incident?
Boslandew ignore it...
