[edit] Development
The Blackburn B-2 was developed by Blackburn as a successor for its earlier Bluebird IV trainer, retaining the layout and side-by-side seating of the earlier aircraft, but having a semi-monocoque all-metal fuselage. The prototype B-2 (registered G-ABUW) first flew on 10 December 1932,[1] powered by a de Havilland Gipsy III engine. A total of 42 B-2s, including the prototype, were built.
[edit] Operational history
The prototype B-2 was shipped to Lisbon in September 1933 for evaluation by Portugal. Although it performed well in the evaluation, the Portuguese preferred a tandem layout, and purchased the de Havilland Tiger Moth[2]. Although not successful in competing for major military orders, the B-2 continued in production to equip civilian flying schools in the United Kingdom, that were busy training pilots for the Royal Air Force under the RAF expansion scheme, with the B-2 equipping flying schools at Brough Aerodrome and London Air Park, Hanworth owned by Blackburn.
The last three B-2s were sold to the RAF and used by No. 4 EFTS (Elementary Flying Training School), also at Brough.
On the outbreak of the Second World War, the aircraft at Hanworth were moved to Brough, and merged with that school's aircraft. The school at Brough continued to be operated by Blackburn, with the aircraft remaining with civilian registrations (although they were repainted with wartime training markings with yellow fuselages, camouflaged wings and RAF roundels) [2]. The remaining aircraft were taken over by the RAF in February 1942,[1] being handed over to the Air Training Corps, where they were used as instructional airframes.

[edit] Survivors
Only two B-2s survived to fly postwar; one crashed in 1951[2], and the sole survivor (G-AEBJ) is preserved and maintained in airworthy condition by Blackburn (now part of British Aerospace). G-AEBJ is located with the Shuttleworth Collection at Old Warden.[3] Another fuselage was for many years seen up a tree in an Essex scrapyard before being rescued in the 1980's. The aircraft displays two identities, G-ACBH and G-ADFO and is preserved, still wearing its original paint, at the South Yorkshire Aircraft Museum.
