Sorry, Genghis and all !
The French always called it Concordski (occasionally spelled Konkordski), never Concordska.
I should know, having lived in France long enough, and having worked on Concorde. Those who don't believe me should check André Turcat's book.
Secondly, it's only the English speaking world that refers to an aircraft as "she".
In French "l'avion" is masculine, so in French you would have "F-WTSS was the first prototype ; he flew (il a volé) for the first time on 3 March 1969", while in English it would be "G-BSST was the British prototype. She flew for the first time on 9 April 1969".
So, are the French Concordes boys, and the British Concordes girls?
And what were they up to when our backs were turned? To find out, you will have to wait for the publication of "Concorde, the Intimate Story"....
