A brief history about the Concorde that pretty much every aviator knows: The Concorde was a supersonic passenger-carrying commercial airplane. Built in the 1960s as part of a joint venture between the United Kingdom and France, the Concorde was the first commercial aircraft of its kind. Only 14 Concorde aircraft went into service before it was retired by both countries in 2003.

But anyways

The Singapore Airlines Concorde was jointly operated between themselves and British Airways. The aircraft, G-BOAD, was a true joint venture, with both airlines taking equal responsibility (and glory) for operating the flights.

It was one of the earliest examples of a codeshare/alliance type partnership in aviation. Although the flight deck crew were always British Airways, the cabin crew alternated by segment between British Airways and Singapore Airlines.

Most interestingly, the aircraft itself was a plane of two halves. The left or port side was adorned with the Singapore Airlines livery, while the right or starboard side was in the British Airways Negus livery.
