The Blackburn B-20 was an experimental aircraft, first flying in 1940, that attempted to increase drastically the performance of flying boat designs. Blackburn Aircraft undertook an independent design study based on a patent filed by chief designer John Douglas Rennie for a retractable pontoon float that formed the planing hull. The Air Ministry was interested enough to authorise and contract for the construction of a prototype, serial number V8914, built at Dumbarton to test the concept. The prototype flew for the first time on 26 March 1940. An improved variant, the B-40, was proposed with Bristol Centaurus engines to meet a requirement for a small general purpose flying boat under specification R.13/40. The surviving wreck of the prototype is now an exhibit in the Dumfries and Galloway Aviation Museum.
