" Terribly sorry", he said in his best Sloane tones: "steer three-seven-zero !" was his final bid.
Heeheeehee,
that old trick!! During my training as a civil ATC we drove simulator blips for each other. As the course progressed and exercises got busier pearlers like muxed-ip callsigns or the old "heading 370" classic were heard quite frequently from the increasingly flustered trainees on the other end. Keeping whatever the radio equivalent of a "straight face" is, without giving the game away (that was the instructor's job) could be difficult sometimes! And of course because we "blipped" for each other, sometimes you were the pilots, sometimes you were the trainee ATC. The shoe was frequently on the other foot.
All good fun, because no-one gets hurt in the simulator.
