Today is the 40th anniversary of Concorde's first flight and to celebrate we have 5 copies of the new book; Concorde: A Photographic History to give away.
To win a copy, simply email your answer to this probing question:
Which airline cheekily claimed to be first in the order queue for Concorde by suggesting its earlier tentative options on Sud Aviation Super Caravelles should remain valid after the proposed supersonic jet became part of the Concorde project?
The closing date for this competition will be the 15th March and the 5 winners will be selected at random from the winning answers and contacted on the week beginning the 16th.
The momentous first flight of the Concorde was covered by Flight International at the time and can be found in our extensive online archives. There is also a piece in the "on this day" series by the BBC.
We have created a gallery for all you Concorde fans to upload your favourite images of the magnificent Concorde and an area for you to share your memories of this icon of 20th century design.
