Long-Haul Flight
I used to work maintenance for an aircraft carrier a fair few years back. On the Boeing 747-400s, there’s a hidden crew rest near the tail. There’s a small staircase, and a bunch of bunk beds up there. I never got to take advantage of this, but when we had to pull out the mattresses during heavy maintenance checks, we’d almost always find opened contraceptives under some of the mattresses.
Apparently long-haul flights had a bit of a reputation of things happening between flight crew (And occasionally between flight crew and passengers).
