A few years ago, a colleague of mine was teaching Gazelle to Army Student pilots at Middle Wallop. On one of the night navigation sorties, the route would take them out along the South coast and away from the more well known ATC lands. Here the students would be introduced to the services that could be offered by London Information. Earlier in the sortie the student had discovered that his PTT switch had a tendency to stick in and it was fast approaching the annoying stage. His opening call went as follows:
"London Information, Good evening, Army Air XXX, (then, discovering his switch had stuck again) "Aw you C**t!"
The totally unflustered reply came back "Army Air XXX, Good evening to you - you B@stard!"
