Hendon used to have RAF Transit accommodation just across the road from the Hendon Police Training Centre. I stayed there a couple of times, on one occasion as we passed through in transit from RAFG to Gib on detachment we arrived at midday to be told we were to be housed at a hotel in Knightsbridge and transport would leave in about six hours meaning we would stand around . Turned out the reason was if they took us now they would have to pay us a meal allowance,, so we simply made our own way to the hotel.
