General Aircraft GAL42 Cygnet (G-AGAX)
General Aircraft GAL42 Cygnet (G-AGAX) at Manchester Airport in March 1955
The Cygnet was initially an all-metal, low wing monoplane designed by CR Chronander and JI Waddington and built in Slough by CW Aircraft Ltd. As first flown, the CW Cygnet was a tail-wheeled, low wing monoplane fitted with a single fin and rudder.
The prototype (G-AEMA), first flown at Hanworth Air Park, Middlesex in May 1937, was fitted with a 90 hp Cirrus Minor engine. The prototype was then progressively modified to feature twin fins and rudders, a Gipsy Major engine and a tricycle undercarriage.
CW Aircraft then sought to develop a twin engine machine, but ran into financial difficulties. 
General Aircraft took over CW Aircraft Limited and acquired the rights to the Cygnet during the spring of 1938. They developed the CW Cygnet prototype into the General Aircraft GAL42 Cygnet II, adopting a more powerful engine and a more streamlined tricycle undercarriage in the process.

The first General Aircraft GAL42 Cygnet II (G-AFVR) completed its maiden flight on 2nd April 1940.
The stressed skin aircraft was an advanced machine for its day and was put into limited production with ten examples being built. Three of these however, did not acquire civil registrations and may not have ever flown.
