I used the Vulcan XL 426 at Southend for a photoshoot for one of my bike magazine articles, and also got to visit the cockpit. Access via a ladder under the nose. Extremely cramped for such a huge aircraft.
The guy I felt sorry for was the flight engineer/navigator - just stuck at a control panel with no view of the outside world. Imagine flying one of those all the way to the Falklands and back (all right, with a comfort break at Ascension). Respect for our RAF heroes!
