Re: Random factoid.
One of my most satisfying moments was in a car with a loud, obnoxious Yank (sorry, friends, they do exist, just like loud obnoxious Brits) telling me how some US aircraft at the local base could fly at 600mph at 65ft. Without thinking I repeated a comment from a colleague formerly in the RAF: "So, high and slow then".
The visit did not go well till I discovered that none of the engineers at the plant could stand him either.
