Do I understand that the US controllers who "fell asleep" were totally alone?
I've slept whilst on watch thousands of times, but never whilst alone and always wearing a headset. I don't know the current rules but whilst the tower controller was expected to use radar and flight progress strips to be aware of inbound traffic during the day, I always used to telephone the tower well in advance for any arrivals during the night. Seems commonsense to me...
When did you ever work nights?
