The CB-1 is a two-seat light aerobatic biplane produced in kit form for the American Hatz Association of Gurnea, Illinois.

Developed by Martin Hollmann of Orlando, Florida, a senior design engineer in the aerospace industry, the HA-2M Sportster [also known as the Hollmann Sportster] was claimed to be the first two-seat gyroplane designed for the homebuilder who has access to a minimum of power tools.

The Series 600 was introduced to the market in 1971 and was powered by two 3,750 lbst Viper 600 series engines with a two-stage turbine.

The de Havilland DH-125 series was intended as a jet-engined replacement for the de Havilland DH-104 Dove executive aircraft, the project being announced in February 1961.

Over the years development of the series continued, one variant being the Series 900XP which was a model which combined the airframe, operating weights and systems of the 850XP model, including the winglets, but which was fitted with the new Honeywell TFE731-50R turbofan which provided a five percent reduction in

The Hastings was designed as a replacement for the Avro York transport in RAF service, and the prototype (TE580) made its first flight at Wittering on 7 May 1946, the second prototype (TE583) being flown for the first time on 30 December that year.

Once the Hawker 800 series was placed in production British Aerospace looked at a further development of the type and, despite being the most capable model of all the various models, only 52 examples were completed.
