Concorde G-AXDN forms part of the Duxford Aviation Society British Airliner Collection and is proudly on display in the Airspace hangar at IWM Duxford.
The British and French pre-production aircraft had several changes in design compared to the earlier prototype Concordes. These consist of a lengthened fuselage, smaller passenger cabin windows, a new glazed visor design and the aircraft were fitted with the Olympus 593-4 engines. The pre-production aircraft were used to further develop the design of the final production aircraft.
Other changes to the design included a different wing plan form that of the prototypes, a larger fuel capacity, and different air intake systems. Both the two pre-production Concordes differed in size and design from each other, the French one which built last, being close to the final production design.
G-AXDN flew faster than any other Concorde! She flew higher and faster than any other Concorde history.
