Official photo taken when G-ADWT was being used for spinning trials during early 1937. The rudder is horn-balanced - as installed on the M.2Y - in an effort to help spin recovery. The enlarged cockpits of the Hawk Trainer made its spinning characteristics difficult to recover from.

First production Parnall Heck 2C featuring fixed undercarriage. Painted in two-tone light and dark blue and delivered to Aircraft Exchange & Mart Ltd, Hanworth, in September 1936 for sales demonstrations. None of the six aircraft built were sold. Registered 23 Dec 1936 to Parnall Aircraft Ltd, Yate. Later painted dark grey and used for communications duties. Impressed as NF749 and delivered to Turnhouse 12 March 1943 for No. 17 Group Communications Flight. Scrapped at Kemble in May 1944.

Four brothers named Moss built the attractive MA.1 two-seater in Chorley, Lancashire in 1937, intending commercial production. In 1938, G-AEST reappeared as a sports model with open cockpits and writer Ben Dunnell thinks this may have been a new airframe; see Alan Scholefield's photos from 1950 when it was a racer with the rear cockpit covered.

Photo shows the sole Lascoter with the Jaguar radial engine, which dates the photo. The first two engines, a Siddeley Puma and a ADC Nimbus. were inline engines. The Lascoter was first Australian designed and certified airliner. First flew on May 25, 1929. Withdrawn from use in 1938.

Operated by the Nederlandsch Nieuw-Guinea Petroleum Maatschappij (NNGPM). The headland shows that the seaplanes used the old harbour in Serui, and not the bay to the west of town. Photo from: Wereldmuseum

Seen at Marsh Leys Farm, Kempston, after the owner, G.A.Chamberlain, suffered the misfortune of a dead-stick landing in a deeply furrowed field. Having bounced off a deep ridge the Dove stalled, dropped a wing, and lost its undercarriage in the ensuing impact with the ground. Following repairs Geoff swapped it for an Avro 504K from Richard Shuttleworth and Warden Engineering converted it into the Pup that we know today. (Geoff Chamberlain photo)

The first production Gladiator, no doubt photographed when new. It was taken on charge by the RAF on 16 February 1937, but was not one of the first aircraft issued to No 72 Sqn at Tangmere. Photo from: Life

Thought to have been photographed at Burbank before delivery. Note that 'Linje' in LOT's name changed to 'Linie' in 1938 following a Polish spelling reform.

Part of the CNAC fleet and used by General Chiang Ki-shek. Crashed near Ruili County-Level City, Dehong Prefecture, Yunnan Province in April 1942 when an attempt was made to reposition the war-damaged aircraft to a safer location. The Julius A. Barr Photograph Album/The Museum of Flight

Fairey P.4/34 was developed as light bomber but lost out the Hawker Henley. However by the time it was ready to enter service the RAF's needs had changes and it became a target tug instead. Meanwhile Fairey use K7555 as the basisof a carrier fighter that became the Fulmar. K7555 was later reinforced and deliberately flown into the weighted cables hung beneath barrage balloons. It apparently survived 300 such encounters. Photo from: Imperial War Museums

The prototype Sea Bird on the ramp outside the Fleetwings seaplane factory. The FAA serial number is confirmed by the log book of pilot William H. Engle whose first flight in it was on 25 March 1937. That and all subsequent flights were recorded as on X16793. The skin is 0.010 thick stainless steel and it has been given a swirl finish to make it look attractive. The wing and empennage structures are also made from stainless steel with fabric covering. Engine is a Jacobs L-5 giving 285 hp. The three-section landing gear fairing disappeared from photos from 1938 on, however this aircraft was seen at Oshkosh 1992 with fairings, although possibly not originals. Texas based as N16793 in 2024. Photo from: Alan Reddig via Tim Martin
