I was in one of those fleets where you go here, go there, jump through this, without much actually happening.
After a lack of action the fleet was heading home, I was crushingly tired after a very very long day.
Suddenly their was silence on comms, I was sitting at a gate and nobody was in local.
It took me a moment or two until I figured it out, which was a clue in itself.
I'd fallen asleep for a short while, apparently still sitting up, long enough for the fleet to move on without me.
It turned out they were still travelling and I'd become conscious during a lull in comms.
So I found my own way to base, logged off and hit the hay.
I found it a bit disturbing though.
