Oh dear that don't sound good.
Had a Scots girlfriend once, when I lived in Poole. (I think she came from the East coast, but not sure.)
Anyway she had a brother in the army back a longish ways now, 70s mebbe. He finished a tour in NI and was coming back with his regiment on an aircraft carrier(?). They were told not to go walking around on certain decks. Well a few did, he was one of them, and he was lost overboard. So no body, nuffin. Really sad.
So hope he has just gone AWOL wiv sum burd and eventually turns up.
