Well, les moderateurs have so far spared the axe permitting my contributions to remain, here's another one regarding UK and US RT.....
Friend of mine was newly minted as an air traffic controller at LHR. Let us call her Belinda. Seems that once qualified, one is detailed to handle the ground control, and so was Belinda, on her very first day on duty - with of course an attentive supervisor to guarantee nothing went wrong.
Incidentally, I met Belinda at my gliding club, not far from LHR -
So after a couple of smooth encounters with early arrivals from foreign parts, the next aircraft to be directed to the stand turned out to be a fellow glider pilot...quite a lot of BA pilots enjoyed that sport in their spare time as it happens, in our gliding club.
So the BA pilot, relaxing from the strict RT discipline of approach and tower, recognizing Belinda's voice on ground control, gave her the big hello...."Hey, Belinda, is that your voice? how's it going?"
Belinda didn't allow herself to be distracted from absolute propriety in directing the cheeky chappy to his place. After three more BA arrivals turned up, each one with a personal hello to a fellow glider pilot, it grew more and more difficult to retain professional discipline. When an American Airlines Pilot who happened to hear the last couple of "Hello Belinda, how you doing?"s broke in with "That Belinda must be some swinger!" she lost it.
The supervisor had to step in.
Since then, her career as controller has been unblemished. But the story is still told.
