When I was doing my O2 course I was told about a group of ten Italian divers who were in the pot. Obviously they were bored, and equally obviously one of them was rather stupid.... he decided that the time would be better passed if he could 'ave a faaag.
<font color='#000080'>I heard one where some russian divers were in the pot getting something passed through the hamburger hatch, when the operator outside thought his side was jammed. He got a large hammer and whacked it, decompressing all inside and sucking one bloke through the hatch (about 10 inches across) and spraying him over the wall.
Too late, he'd bred - his son was driving.
Mind you, looking at the photos on various sources (- haven't looked at Stuarts yet) it doesn't look home made to me. It has an uncanny similarity (and spec) to ex TUP pots sold by a fairly local navy to another navy a while ago.
