Bondage
The bondage story is correct. Must have been around 1980. It was at Gatwick and the FA was called out for a short European trip, to Brussels or Amsterdam, I don't remember exactly. The local Plod had to be called to release the poor fellow. Imagine being tied up in a darkened cupboard when you hear Size 12s pounding up the stairs!
However, the episode was reported in 'The Log' at the time, with a competition for the wittiest message from the Captain to the Airline explaining the predicament.
