I heard that this movie was so bad, so at first I had no plan to watch it. Last night I did and actually it was not as bad as I thought. The Concorde is gorgeous... and it flies at twice the speed of sound.
The plot, although is not very good, also not bad. Robert Wagner plays an arms dealer who wants to murder one of the passengers of the Concorde. There are also side plots on several other passengers and crews. Best moments, in my opinion, are when the Concorde is under attack.
