Design and development

The B-3 was based on earlier B-2 Miss Los Angeles single-seat racing monoplane.[1] For the day, some advanced features were included such as Handley Page leading edge slots and single-slotted ailerons and flaps on the wing trailing edge.[1] The B-3 was powered by a 290-horsepower (219 kW) Menasco C6S-4 Super Buccaneer inline piston engine. A proposed two seat-variant, the Brown B-3 Super Sport had two seats in tandem under an enclosed cockpit. No orders were received, and the project died.

Operational history

Intended as a long-distance racer as well as a touring aircraft, only one Brown B-3 (NX266Y) was built and sold to Dr. Ross Sutherland from Los Angeles. On October 10, 1943, the aircraft was destroyed in a hangar fire at Van Nuys Airport, then known as the Metropolitan Airport.

The Brown B-3 is featured in Flight for Freedom (1943) as the racing aircraft flown by the lead character. [2] The B-3 is featured as a prototype fighter aircraft in Flight Lieutenant (1942) and crashes out of shot in the final scene. The B-3 can also be seen sitting on the ramp during the scene of Humphrey Bogart's famous goodbye in the film Casablanca (1942).[1]
