what is it?
The SAAB 21 is a Swedish single-seat low-wing monoplane fighter and attack aircraft designed and manufactured by SAAB. Its twin boom fuselage with a pusher engine gives the aircraft an unusual appearance. Work began at SAAB following a Swedish Air Force decision to embark on a major expansion programme in preparation for the possibility of being drawn into the Second World War. The company designed a monoplane twin-boom aircraft, powered by a single Daimler-Benz DB 605B engine that was positioned at the rear of the fuselage nacelle, driving a pusher propeller.
How to recognise it: 1 piston engine with propeller · low wing · retractable tricycle gear · 11.6 m wingspan
