A beautiful Concorde, once the pride of Air France, is kept as a memorial next to the runways in CDG airport in Paris. This is the closest I could come on an evening walk around the airport. To catch an early flight tomorrow morning I stay this night in a hotel close to Terminal 1.
If I would be in Arlanda, the Stockholm airport, I could stay in a retired Boing 747 remodeled into a hotel: http://www.svenskaturistforeningen.se/PageFiles/28463/jumbo_545x300.JPG
As exclusive the Concorde was it has no practical use anymore except as a resting place for some starlings which were swirling around in the evening air.
(If you have to stay in a hotel at Charles de Gaulle Airport, I can recommend this Ibis
called IBIS CDG Airport /Roissypole, 3 rue de Bruxelles, 932 90 Tremblay.)
