Dolley I love that one!
One I heard was similar to gib but ocurred at a deserted checkin desk during checkin for a delayed flight out of Gatwick. The supposed perpetrator is now an easyJet manager!
Apparently two loaders pulled a dog kennel from an aircraft and found it frozen stiff and very very dead. It was apparently 'defrosted' on the A/C brakes for a while before being placed back in the kennel to die of 'natural causes.'
A shift on this is where the loaders, fearing legal action, claimed to the owner that the dog had been mis-sent to the wrong destination and replaced the dog with a lookalike. When the dog was delivered a couple of days later the dog's owner had a heart attack when she saw it as she was actually transporting the pet home for burial!
I also heard one where a ramp worker took pity on a dog that was getting hot and panting away in an aircraft hold as the flight was delayed. He fashioned a lead and walked the dog round the ramp for a bit. On returning the dog to the cage he read the sign on the top. "DANGER: WOLF. Property of Chicago Zoo..." or so it goes.....
