There was a time when one could well speculate whether certain Master Controllers could remember their own name, let alone their phone number. Several were borderline cases (if not actual cases, come to think about it) for the men in the white coats that used to look after Inspector Dreyfuss.
For example, a certain tired and emotional character (an ex pilot as it happened) was responsible for teaching MCs at the SFC a few years ago. Part of his QRA lesson involved 'briefing the Intercept Controller' at Saxa Vord. There had not been controllers on the Outer Islands for several years at that stage after the introduction of remote access technology. Even after being corrected he carried on regardless. Another revealed to me - on the top of Mt Kent in rather inclement weather - that he was never happier than on a mountain in the middle of nowhere with a radar on the top!
Thankfully the current bunch of MCs are not in the same category as some of their predecessors!
