Many moons ago I was stationed at Brize Norton and I remember the RAF Regiment Officer telling me a great story. A Canadian Armed Forces 707 en route from Germany to Canada made an emergency diversion into Brize when a suspect package was found in one of the rear loos. The package was making a ticking noise.
The aircraft landed safely and was directed to the remote parking stand reserved for the purpose. The steps were put up and the Regiment officer shot up to the top of the steps. The passenger door opened and a crew member handed him the package and then promptly shut the door again!
My chum was left standing there with the ticking parcel in his hands feeling just a little lonely.
It turned out to be a Swiss cuckoo clock!
