The first A320 for British Airways seen at Blagnac wearing its French test registration. Note that in common with other BA aircraft, the last two letters of the British registration are repeated on top of the fin. However the last two letters were not "SA" as shown. This was G-BUSB. The mistake happened because this aircraft was ordered by British Caledonian and G-BRSA had been reserved for it. When BA took over BCal, it kept the A320 order but changed their registrations. It is not known if the mistake was corrected before delivery on March 30.
This was the second A320. At one stage it wore British Caledonian markings but by March 1988 was in Air France's livery. It was finally delivered to Air France in 1991 as F-GFKQ and scrapped in 2009 without a further change of ownership. F-WWDA is a now regular Airbus test registration and has been used on other A320s.
