Been in a Vulcan too. The one at the Scottish air museum near Edinburgh (it bombed Port Stanley in the Falklands). They had an "open cockpits day" years ago. The Vulcan's cockpit was tiny but it had a crew compartment just behind. There were these rubber bottle things with a wide opening at one end that most visitors were putting over their mouths, thinking they were for oxygen. Then they'd be told by the museum guy that they were actually for peeing into. Luckily, I wasn't caught out.
I lived a mile and a half from that museum and managed to get into some great planes over the years. A friend of mine was in their restoration society, so I got to watch them rebuilding a Spit V. Nice.
Moved away from that part of the world, so I haven't been to the museum for years. Well worth a visit though. There's a Concorde there now. They've got a Komet and a Comet, Lighting, Venom, Meteor, Spit 16 ( I think) and loads of other stuff, including some interesting transport planes from the past.
