Lion
In 1931, the Lion Aircraft Co. was organized in Chicago. That same year, the first instance of the Lion Safety Plane (X12074) was built. This was a two-seater braced high-wing monoplane, initially equipped with a 45 hp Szekely SR-3 engine. The aircraft’s powerplant was soon replaced by a 50 hp Aeromarine engine, and later by a 55 hp Velie engine.
Brazilian Development and Innovations
The second aircraft (12810) was built the following year in Brazil by the Brazil Aircraft Corp. This plane, known as the Brazil Lion, was fitted with a 50 hp Aeromarine engine (later replaced by a 65 hp Lambert) and featured many technical innovations. These included an autopilot, landing gear brakes, and an electric starter.
The Mystery of the Brazil Lion
In 1932, the Brazil Lion aircraft was brought to Detroit to participate in an aviation exhibition. The machine made a good impression, and preliminary orders for 20 production units were even received. However, a detective story began shortly thereafter.
The aircraft’s designer disappeared, taking the plane with him. He was later found, but there was no further talk of any serial production for the promising Brazil Lion.
