411A,
A couple of these guys have been hauled over the coals in the office for nodding off at a moments notice, day and night. OK, we all get tired and drop off from time to time but the idea is to let everyone know, SOP's etc, but a couple of them have almost lost control of their ability to stay awake, you think they'd get the picture and throw in the towel.
I flew with one a while back and after 2 hours in the bunkroom he got back in the RHS, and promptly fell over onto the right window and sidewall. I honestly thought the guy had kicked the bucket.
Send them off on a 9 day tour of duty with the boss, who's aware of what's going on, and all of a sudden they can stay awake.
Uncanny isn't it?
