The Snark research aircraft G-ADDL c/ DB.2 was designed by Dr. N.A. de Bruyne and built by Aero Research Ltd in 1934. It was built to test low weight, bakelite-bonded plywood, stressed skin wing and fuselage structures
Apart from the structure the Snark was a conventional looking low-wing four-seat cabin monoplane, powered by a nose-mounted 130 hp (97 kW) de Havilland Gipsy Major piston engine. Registered G-ADDL the Snark first flew from Cambridge on 16 December 1934 flown by de Bruyne.
