The Handasyde glider was a single-seat monoplane glider, designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. It finished in second place to a French tandem-wing machine.
In August 1922 the Daily Mail newspaper offered a £1,000 prize for the longest duration flight by an unpowered, heavier-than-air aircraft. The competition was to be organized by the Royal Aero Club, who chose the site (Itford Hill, on the Sussex South Downs near Lewes) and the date (16–21 October). This gave competitors six weeks to design, build and transport their entries; [1] 13 arrived in time and one of these was the Handasyde glider, competition number 2, to be flown by F. P. Raynham. [2]
George Handasyde designed the glider for Raynham, assisted by his draughtsman Sydney Camm. The Handasyde Aircraft Co. had no manufacturing capability, so the aircraft was built by Louis Blériot's Air Navigation and Engineering Company (ANEC) of Addlestone, Surrey. It was an all-wood aircraft with a thick, high, cantilever wing with a slight straight taper and square tips. The unusual obtuse triangular ailerons reached to the wingtips, where they had their greatest chord. [2] Control of the ailerons was also unusual; their control wires did not go to the base of the control column but instead ran into the cockpit, where the pilot worked them with his left hand. [3] The all-moving tailplane was rectangular, the fin triangular with a vertical hinge line for the quadrilateral rudder which sloped upwards on its lower edge to provide tailplane clearance. [2]
The fuselage had flat, parallel sides which tapered in depth aft of the wings. The single-seat cockpit was just behind the wing leading edge; with the pilot in place, a rear-hinged, rectangular piece with an aperture for his head folded forward to complete the upper wing surface. In front, the flat fuselage sides curved inwards and were rounded at the nose. The glider sat on a pair of skids mounted on the lower fuselage longerons, with the wings protected by wire loops reaching from the main spar below the wing to the leading edge. It also had a small tailskid. [2]
Despite blustery conditions throughout the week of the competition, Raynham flew the Handasyde several times. After some practising over the weekend, he made two competitive flights on Monday 16 October, the better of which lasted 11 min 23 s. [3] Learning from the approach taken by Fokker, who had more gliding experience, he greatly improved his time the following day to 113 min and looked set for the Daily Mail prize. There was little flying on Thursday because of the winds, and the Handasyde team took the opportunity to fit a rudder extension and increase the aileron deflection. However, on the afternoon of the last day, Saturday 21 October, the French pilot Maneyrol stayed up for 201 min in his tandem-winged Peyret glider. [4] [5] Raynham made another flight but this was brief and he had to be content with the £50 Ogilvie prize for the best British flight on the first day and another £10 prize, from the Seaford Chamber of Commerce, for the longest straight line flight. He was later awarded the Britannia Trophy for the most meretricious British flight of the year. [6]
After the Itford competition the Handasyde took part in filming around the Devon coast and was lost after ditching. [2]
A second Handasyde glider was sold to the Canterbury Aviation Company of New Zealand in 1923. [7]

General characteristics
The Slingsby Type 42 Eagle was a two-seat glider designed in England from 1952.
The de Havilland DH.52 was a single-seat, high-winged glider produced as an entrant to a 1922 prize competition. Two were built but insufficient torsional stiffness in the wings led to control problems and the DH.52 was rapidly abandoned.
The Handasyde monoplane was a single-seat light aircraft built for the 1923 Lympne motor glider competition. It competed there but won no prizes.
The Slingsby Type 51 Dart is a single seat competition glider designed in the early 1960s, initially as a 15 m span Standard Class aircraft but evolved into an Open Class, 17 m sailplane. It was the last Slingsby sailplane to be mostly constructed of wood.
The Slingsby T.43 Skylark 3 was a single seat Open Class sailplane developed from the Skylark 2 with an extended wingspan. It won the 1960 World Gliding Championships.
The Slingsby T.50 Skylark 4 was a British single seat competition glider built by Slingsby Sailplanes in the early 1960s. It sold in numbers and had success at national, though not world level competition.
The EoN 460 series are wooden single-seat standard class sailplanes, built in the UK in the 1960s. It did not have major competition success but some remain in use in 2017.
The Gordon England glider was a single seat glider designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. It made some competition flights but was damaged on the last day.
The Sayers S.C.W. was a single seat monoplane glider, designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. Unresolved control problems stopped it from making any competitive flights, but it flew successfully later in the year. It was destroyed on the ground by a storm in December 1922.
The Merriam glider was a single-seat monoplane glider, designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. It crashed at the start of its first competitive flight but went on to be converted into a dual control training glider.
The Airdisco Phi-Phi was a single seat monoplane glider, designed specifically for the first British gliding competition held at Itford Hill in 1922, an endurance event. It recorded one competitive flight but crashed on a second attempt.
The Brokker was a single seat glider entered into the first British gliding endurance competition, held at Itford Hill in 1922. It combined the wing of a Fokker D.VII with an engineless Bristol F.2 Fighter fuselage. It flew well in the stiff winds of the last day and achieved the third longest flight.
The Peyret Tandem or Peyret Alérion, was a French single seat glider of tandem wing configuration. It won first prize at the first British Glider Competition of 1922.
The Hannover H.1 Vampyr was a German glider designed by Georg Madelung for the 1921 Rhön gliding competition held at the Wasserkuppe, from 8 August to 25 August 1921. The Vampyr was probably the first heavier than air aircraft to use stressed skin, it has been claimed as the precursor for all modern sailplanes.
The Dart Cambridge was a single-seat competition sailplane built in the United Kingdom in the 1930s. A development of the Grunau Baby, only two were built, flying with gliding clubs.
The Davis-Costin Condor was a conventional all-wood, tandem-seat sailplane built in the United Kingdom in the 1950s. Only one was constructed; it was later rebuilt with a longer fuselage and other detailed alterations as the Condor 2.
The Nyborg T.G.N.1 was a single-seat experimental sailplane built in the early 1930s, its unusual wing design a scaled-up version of the wings of large birds.
The Penrose Pegasus was a 1930s high-wing, single-seat, wooden glider from the UK. Designed, built and flown by Harald Penrose until the start of World War II, only one was built at the time though a reproduction was constructed in the 1990s.
The Scott Viking 1 was a single seat, high-performance glider designed and built in the UK just before the Second World War. Only four were constructed, one setting records in Argentina and another remaining active into the 1980s.
The VTC Delfin is a competition single seat Standard class glider designed and built in Yugoslavia in the 1960s. It had some success in national competitions and went into small scale production.
