HOODED and Bahrain Lad,
Sorry guys, but the reason aircraft manufacturers make aircraft is so they THEY make a profit through selling sufficient airframes at sufficent prices. For Concorde, magnificent technological achievement that it was, to be considered a commercial success, it's MANUFACTURERS would have to have made a profit from it....That was not the case to the tune of untold BILLIONS of Pounds /Francs.
Would have love to have flown her...but glad I didn't foot the bill for building her.
