The Cold War was a unique time. It was technically peacetime but even the normal workdays reflected the deadly seriousness of the situation. Sure, go get that beer at the pub, but not until your equipment is ready to roll.
Air Refueling Tankers in the Cold War had a similar mission: TOAD (Take Off And Die).
In the event of a nuclear war, the tankers were to scramble & offload as much of their gas to the B-52s as possible. Which wouldn’t leave enough for them to get to a runway. It was expected they would ditch the jets, most likely dying in the process.
Not that there would likely be any bases to go back to anyway.
