The General Aircraft Monospar ST-25 was a British 1930s light twin-engined utility aircraft.
The Monospar ST-25 was a low-wing cantilever monoplane with a fabric-covered metal structure. The monospar name came from the use of a single spar in the wing structure, that had been developed by H J Stieger. The cabin was enclosed with five seats. It was based on the GAL Monospar ST-10, with the addition of a folding seat for a fifth passenger, extra side windows, and the addition of a radio receiver. On 19 June 1935, the prototype (G-ADIV) made its first flight at Hanworth Air Park. It was designated Monospar ST-25 Jubilee, to honour the 25th anniversary of the reign of King George V. [2]

The Bristol Type 170 Freighter is a British twin-engine aircraft designed and built by the Bristol Aeroplane Company as both a freighter and airliner.

It remained in service until 1936, equipping No. 101 Squadron RAF. It was an agile and relatively fast aircraft that was capable of aerobatic manoeuvres such as loops, rolls and spins.
The Vickers Virginia was a biplane heavy bomber of the British Royal Air Force, developed from the Vickers Vimy.
The Hawker Hornbill was the last Hawker military aircraft designed under the direction of George Carter. The design was started in 1925 and the first flight took place in July 1925. The Hornbill did not achieve service in the Royal Air Force due to problems in its power plant and radiator. Only one aircraft was built.
The Airspeed Consul is a twin-engined light transport aircraft and affordable airliner designed and produced by the British aircraft manufacturer Airspeed Limited. Introduced during the immediate post-war period, it was a straightforward conversion of surplus Airspeed Oxford military trainers that had been extensively used during the Second World War.

The Airspeed AS.39 Fleet Shadower was a British long-range patrol aircraft design that did not go beyond the prototype stage. A similar aircraft, the General Aircraft Fleet Shadower, was also built to the extent of prototypes. While the concept of a fleet shadower had some promise, the resulting designs were soon overtaken by wartime developments in airborne radar.
The de Havilland DH.50 was a 1920s British large single-engined biplane transport built by de Havilland at Stag Lane Aerodrome, Edgware, and licence-built in Australia, Belgium, and Czechoslovakia.

It was of wooden construction and has fitted with a retractable nosewheel undercarriage. One feature of the design was that instead of a 2 + 2 seating, the pilot sat in front to the left, and all three passengers were on a bench seat to the rear of him. Alternatively, when being used as an air ambulance aircraft, it could carry a patient on a stretcher, which was loaded through a hatch in the aircraft's nose. The F.25 was evocative of the pre-war G.I design.
