Lead Wet's headset u/s was it? Or was this the same AEO who (admittedly a couple of years after 1980) used to spend much of his time while we were in contact leaning over the wet teams' shoulders and, using one of those extending pointer things, repeatedly point out various lines on the AQS901 CRT and ask what they were? A system he thought worked rather well until his pointer suddenly developed a 90 degree bend and would no longer retract and fit into the pen pocket on his flying suit.
I always found the 11 point dividers handy for the AEO problem!!
