Although Concorde received orders from airlines such as Pan Am, Continental Airlines, American Airlines, TWA and Qantas, the project was hit by a number of cancelleations due to the crash of the Soviet Tupolev Tu-144 at the Paris Le Bourget air show crash. On top of this the airlines were concerned about the environmental issues which included the take-off noise, pollution and sonic boom. In the end only British Airways and Air France took deliveries of Concorde although BA did share a Concorde with Singapore Airlines between London and Singapore International Airport, it was painted British Airways Livery on one side and Singapore Airlines on the other.
