Forget, Indeed. I remember Mick Hibberd as an old man
Also Taff Traylor. I seem to remember this was about the time that the AEO had to respond to an encrypted morse question with an encrypted reply.
Questions along the lines of "What is your eta FDP?" or "What is your estimated fuel at FDP?" Such multi-choice questions could then be answered with "1012" or "12000lb" etc.
As the AEO wrote down the received code the plotter would decode the message. As the plotter decoded the message the radar would select the correct prepared and encoded answer. As the meesage receive was acknowledged the AEO would immediately respond.
One crew go zero penalties for response delay and 100% penalties for wrong answer!
