Could have been dropped! I was talking to my lad, he worked in the warehouse for one of those large firms (ruby murray) and he said that when they were busy, lads used to climb the racking and push items off the shelves, "it's ok they're well packaged". He said he's seen washers, dryers, tv's, all sorts dropped to the ground, often from a considerable height. Apparently some of the lads did this when they were busy to avoid having to wait for a forklift, he said that the period he worked there leading up to Christmas, there was more gear dropped to the floor than lifted by stacker truck.
It was all about getting gear on the vans, nobody seemed bothered how it was got of the racking, just get it off! Now the packaging may prevent the carcase from being dented, but a drop from 20 feet or so can't be good for the internal parts.
