Some of my favourite cheating stories come from the Prestwick test center.
There was allegedly a group of middle eastern students who all wore the same T-Shirts with arabic writing on the back, story goes that they changed their shirts between each exam - guess what the text was?
Another story was about a French or German student who managed to rebuild the standard calculator that used to be issued in the CAA exams into a programmable one with a whole bundle of information stored. The pipe smoking, Star Trek Admiral became suspicious when the candidate was using his calculator an awful lot.
What I could never understand was, anyone who was smart enough to come with this sort of solution to a problem, shouldn't have needed to cheat
