How much would it cost to convert one of these airframes into an ultimate full motion simulator experience? A full motion simulator that could be experienced from both the cockpit and the passenger cabin?
Imagine placing the entire airframe on a moving arm inside of some kind of projection 'bubble' - offering a nearly 360 degrees projection field in all axis. As passengers enter Concorde via an airbridge an image of the actual stand, terminal, airport buildings could be projected. The aircraft could virtually taxi to the runway - then the sound of engines, vibrations, acceleration, moving tarmac, rotation, climb rate - all that could be simulated. Landing gear would retract, ailerons would move. A transition to the flight at supersonic speed phase - perhaps in a 'premium' experience authentic Concorde meals could be served?
Concorde would 'live', BA would have the ultimate publicity 'toy'.
I doubt a project of this magnitude is possible to be financed based purely on voluntary donations, but if BA could partner up with some of the technology partners needed to make this happen (for example a software giant that also manufactures a known flight simulator, a chip giant that manufactures leading graphics chips, another chip giant that manufactures the bits used in projectors ...)- perhaps it could be viable?
