The wikipedia entry describes F-BTSD as 'near airworthy'
Concorde - Wikipedia, the free encyclopedia, but who was this written by?
I visited
G-BOAF in Filton less than a year ago, it looks largely complete, but 'maintenance' is pretty much limited to keeping it polished and shiny for the visitors. They were trying to raise £1M or so to put it under cover, you can see on Google Earth that even the taxiway to its final resting place has been grassed over.
Lets pretend for a minute that all the challenges for getting one airworthy are technical and political, rather than financial (for the Bransons/Pages/Brins of this world, £10M is sofa change) If it can be done with a Vulcan, just for a few airshow flybys now and again, exactly what are the issues with doing this again?
