BAC Concorde G-BBDG
one Concorde aircraft built for evaluation testing
G-BBDG, known as "Delta Golf", is the British development Concorde built for evaluation testing. Along with the French Concorde F-WTSB, the aircraft was used to enable sufficient testing to allow for the Concorde fleet to receive certification. On retirement the aircraft was stored at Filton airfield from the mid-1980s until 2003, when she was transported by road to the Brooklands Museum in Weybridge, Surrey.
History
G-BBDG first flew on 13 February 1974, having been registered on 7 August 1973. Delta Golf's main uses were finalising the Concorde design and certification prior to Concorde entering passenger service.
There were some differences between this aircraft and the final production aircraft, such as a thinner fuselage skin. The aircraft was painted in British Airways livery throughout the testing period.
The final flight of Delta Golf was on 24 December 1981, the aircraft had flown a total of 1282 hrs 9 mins.
After the final flight, Delta Golf was stored at Filton in a state of semi-airworthiness throughout 1982 where it could be returned to flight in two weeks if required. However this was never required, and the aircraft was eventually bought by British Airways as part of a Concorde support buy-out in 1984.

Why this record matters
“BAC Concorde G-BBDG” is worth following because a concise public description often conceals a longer documentary argument. Here, Concorde, G-BBDG and aircraft provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Mar 21, 2026. The linked authority identifier is Q5511883. Authority coordinates are 51.355, -0.464. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2003, 1974, 1973 and 1981.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
