Re: Supersonic shock waves are not the only thing that goes boom
"Concorde was a spectacular commercial failure" - not on the scale of the Tu-144 which made a grand total of
55 passenger flights and nowhere near the Boeing 2707 which consumed a billion dollars without even getting to
prototype stage. Meanwhile BA were able to operate the thing at a profit, once they'd realised that the passengers
neither knew nor cared how much the tickets cost.
I don't know why the article describes the Tupolev as "small" - it was larger then Concorde.
