I spent a week or two on the USS Lexington back in the 70’s, and it sucked.
It was one of the worst experiences I ever had on a ship...the ventilation wasn’t working, so it was hot as hell, and I think there was bunker fuel venting into the compartment...it made me sick...I felt nauseous, couldn’t sleep, I could taste it in my mouth.
Man, just the memory...I remember lying in that rack, tossing and turning, having bad dreams when I did fall asleep for short intervals.
I was never so happy to get off a ship.
That was reportedly about the experience (sans bunker fuel, plus jet fuel in some cases) of most sailors on the last few cruises of Enterprise.
