Will be awesome to see it flying again. So advanced for its time.
Sadly the poor cleanup of runways seemed to cause a bad reputation and got them grounded.
Yes - I never figured that out. The one and only crash involving a Concorde ultimately ended with its being withdrawn from service?
If other aircraft types were withdrawn after a crash there would be nothing flying.
I suspect money and perhaps noise regulations (and maybe fuel economy) played a huge part.
