This montage photograph shows G-ADNL in its original form (top) and final form. By installing two Palas turbojets and after modification to the airframe, the maximum speed of G-ADNL was increased by 50 m.p.h.

Two photographs of G-ADNL taken at Shoreham on August 2, 1952 during the later stages of conversion to the Sparrowjet.

The two 330lb st Palas turbojets were neatly buried in the wing roots.

Another photograph showing Fred Dunkerley flying the Sparrowjet. The Sparrowjet's unstick speed was around 60 m.p.h. at 33,800 rpm. The take-off run to clear 50ft was about 500yd on grass and 400yd from a tarmac surface.

The comfortable cockpit had a built-in back-type parachute and Sutton harness and a full blind-flying panel. The de Havilland panel cockpit canopy afforded superb vision for the pilot and was free from any optical aberration.
