In a special Key Publishing magazine on Concorde, Kevin Tate recalled the experience of flying as a Concorde passenger on a route operated by dual-branded aircraft.
I was extremely lucky and very privileged to fly Concorde on the London-Bahrain-Singapore-Bahrain-London service on its second-to-last flight out and its final flight back. This came at the end of the second attempt to make this Concorde service a success. The first was withdrawn in 1977 after complaints from the Malaysian Government of the sonic boom in the Strait of Malacca while India refused permission for supersonic flights over its territory. The second attempt began on January 24, 1979, and sadly ended November 1, 1980.
The flights on the rekindled route would be operated by Concorde G-BOAD, which had been specially painted for the occasion with Singapore Airlines’ colours on the port side and British Airways on the starboard.
