Oops!

An Iranian politician has come to grief over a little matter of his false claim to an Oxford degree. Apparently the 'certificate' carried a spelling mistake, and that reminded me of a case from years ago when a man we convicted of an airline ticket fraud then turned out to have pleaded guilty to obtaining a pecuniary advantage by deception among a handful of other charges. He claimed to have a degree in engineering, but his fake certificate spelt it 'engingneering'. Apparently he had been doing a perfectly good job for some years, but his employers had to sack him nevertheless.
I don't suppose computer tickets let you do it any more, but our man had altered the 'Y' signifying economy class, to 'F' for first, and had put a number 1 in front of the fare.
