I was having lunch today with some War Year vets. During the stories and conversations about the 60's and 70's, they referred to working a "Chinese 72". Anyone out there who can explain a Chinese 72?
Chinese 72 is when a FF has 72 hours off in between day tours and night tours. Normally it is 48 but roughly once a month it is possible to catch a 72. It is just how the 25 group system works.
