[I must have been dreaming watching all those sunrises from 20k ft, 6 or 7 hours after take-off, still strapped to my ejection seat.
Just another jockey: I obviously forgot about the QRA chaps who stayed at work after the rest of the Sqn went to the bar but most of the FJ stations shut at 1700 on weekdays & didn't open at weekends, at least the ones I was at did. The late lamented secret Wiltshire airbase & the Oxfordshire airport are (were) 24/7, at least for the aircrew & those supporting flying. Adminers & other assorted folk still stick to the weekday hours.
