Here's one from long ago... maybe someone older than me can confirm or deny it..??
What we now know as LTCC (ex-LATCC) used to be the Southern Air Traffic Control Centre in a building on the north side of Heathrow. The name was written on the side in huge letters. At the time the Centre Superintendant was one Len Winter.
Some work was going on requiring the temporary removal of the name letters.. and Len came to work one day to find 50 juggernauts queued up outside SATCC. Some wag on a night duty had put some of the letters back.. to read LEN'S CAFE!
