Jon Pertwee had a narrow escape in WW2
"He was on HMS Hood just before she sailed. He was called to an interview withe Captain, not realising it was the interview for his C.Q,. officers course. anyway as he said 'he passed and expected to go on the course when he returned. Instead he was straight over the side onto a trawler and away."
So what would have happened if he hadn't had that narrow escape and sadly perished with his crewmates.
