Ahh Brize Customs..... Used to board before us, open briefcase, put in lunch from galley, pick up honesty chits and depart, never ever saw the movers open the freight doors before us, as we never let anyone near until we had put the pins in. I do remember the new young mover being told to put the engine blanks in the fwd freight hold, asking where it was he was told walk down the right hand side until you find an opening and pop them in there, he did, sadly the door was shut so the first opening he found was above the main gear doors and the blanks were duly slung in to sail serenely back to earth when the gear was retracted.
