SOS Concorde (1979)

Not to be confused with The Concorde: Airport '79  (or The Concorde: Airport '80 if you saw it in Europe), the film it is intended to cash in on, SOS Concorde (aka  Concorde Affair '79) is a typical Italian potboiler of its era.  Directed by Ruggero Deodato it features the usual line-up of US actors whose careers were on the slide, looking for a payday in Italy, including James Franciscus, Joseph Cotten and Van Johnson.  As can be seen from the French trailer, it throws all manner of elements into the plot, from underwater sequences, shark attacks and shoot-outs to boat chases and imperilled airliners.  The plot itself has something to do with a Concorde test flight crashing into the sea near Martinique, the result of sabotage by business cartel (led by the inevitable Edmund Purdom) which is involved in selling non-Concorde airliners to South American countries.  

Judging by the trailer, the model work looks surprisingly good in the crash sequences and overall it all has the sort of slickness characteristic of Deodato's films.  The mix and match approach of the various elements and genres is reminiscent of the director's The Atlantis Interceptors, which likewise threw in elements culled from various other recent films.  Never less than versatile, Deodato's next film would be Cannibal Holocaust, probably his best known picture, which became notorious after being labelled a 'video nasty' in the UK.  I'm not sure if SOS Concorde ever had an English language version, although it was dubbed into multiple European languages (under multiple title variations).  So, if you don't like the French trailer, here it is in German, instead (as Das Concorde Inferno):
