Folks, there is a static display of the Concorde inside a hangar at the Museum of Flight, East Fortune Airfield in East Scotland, half an hour or so from Edinburgh. You can board the aircraft and travel through the cabin. At the time of my visit some areas of the floor were removed so visitors could see the hold area.
The Concorde aircraft was G-BOAA and the aircraft on display is the original aircraft without the return to service mods required after the Paris accident.
The visit is a tour / experience including a short film, walk around the exterior and also, an engine on display. You then finally board the aircraft. The cockpit was roped off at the time of my visit.
The museum has many other aircraft on display including a 707 and Nimrod forward fuselage.
