At first I noticed the TC go down to 1, so asked for the nearest visual contact, which replied with the likes of
"nearest contact, bearing 300, range 0m" - headed up top side but couldn't see anything, so asked again and it was now bearing 190 at 300m (presumably it was a task force or some such and one had already passed without notice) - then that pops out of the mist and I crash dive ASAP, somehow I managed to go undetected though, guess they were even less awares than I was.
