I recall a story about two F111's transiting to LFA 15, in the early 70s, c/sign Sperm 01 and 02. Said acft were receiving "service” from a female controller from a certain atcru in Northern England. She is reputed to have said, in a plum, cut crystal voice:
"You are now entering my dark area, ceasing radar service".
The leader responded in a laconic Texan draw:
"OK. Wriggle, baby wriggle"!
