Not quite the same thing, but I flew to Prague and back a while ago and witnessed the extraction of the baggage from the hold at both ends. In Prague, they inserted the baggage conveyor into the hold and items were transferred fairly carefully into the carts of the baggage train - in Birmingham, the chap in the hold just flung them out of the hatch onto the concrete, where another chap picked them up and flung them 15-20 feet into the wagons - several missed and fell onto the concrete again. The conveyor was there, but probably too much trouble to use....
