A theme developing over these, but....
There was a young JN on the most junior GR1 sqn who had picked up the nickname "Lizard" whilst going through Nav trg. Not sure why....
Anyway, during his convex training, at the end of a debrief he said he didn't want to be known as Lizard anymore.....end result....you guessed it....
And a good friend of mine whose name was Cy, pronounced Si as in short for Simon. A dull air trafficker saw his name and insisted on calling him C Y as in each letter pronounced, even though he was told how it should be pronounced!
There are of course, the endless list of name badges mostly worn at airshows, some of which have already been mentioned.
