In the 60s, in Bomber Command, things were very simple. Startex was all hands to the wheel, about 5-6 hours after the start everyone flew off to dispersal with QRA plus one at main base and the odd post-service recovery flying off a couple of hours later.
Come tea time not a soul to be seen. Just about everyone off at dispersal and the bar still open for the off duty ops, atc and an engineer.
The order book was about 20-30 pages, if that.
