Schneider Trophy

The 1923 trophy, contested at Cowes, went to the Americans with a sleek, liquid-cooled engined craft designed by Glenn Curtiss. It used the Curtiss D-12 engine. US Navy Lieutenant David Rittenhouse won the cup,[5]^:242 and his teammate Rutledge Irvine was second in an identical aircraft. The British Sea Lion III (flown by 1922 winner Henry Biard), and the French entry withdrew from the race.[13] The preparation of the United States team, backed by government support and using Curtiss racing biplanes derived from inter-military competitions, increased the speed and the investment of a winning entry significantly. In 1924 the competition was cancelled as no other nation turned out to face the Americans: the Italians and the French withdrew; and both British craft crashed in pre-race trials.[3] In 1925 at Chesapeake Bay the Americans won again, with US pilot Jimmy Doolittle winning in a Curtiss R3C ahead of the British Gloster III and the Italian Macchi M.33.[14] Two British planes did not compete (R. J. Mitchell's Supermarine S.4 and the other Gloster III were damaged before the race). Two of the American planes did not finish.[5]^:242

Benito Mussolini instructed the Italian aircraft industry to "win the Schneider Trophy at all costs" and so demonstrate the effectiveness of his Fascist government.[3] In 1926, the Italians returned with a Macchi M.39 and won against the Americans with a 396.69 km/h (246.49 mph) run at Hampton Roads.[5]^:243 The United States, short of funds, did not develop new aircraft for the 1926 title defence; the M.39, designed by Mario Castoldi, used a Fiat AS2 engine and was streamlined in the manner of the 1925 Supermarine and Curtiss entrants. The American teams withdrew from further competition after the 1926 race, as the military were unwilling to fund entrants.[3][15] In 1927 at Venice the British responded by enlisting government backing and RAF pilots (the High Speed Flight) for the Supermarine, Gloster, and Shorts entries. Supermarine's Mitchell-designed S.5s took first and second places; no other entrants finished. The race was witnessed by an estimated 250,000 spectators.[16] 1927 was the last annual competition, the event then moving to a biennial schedule to allow for more development time under mutual agreement.[5]^:244

In 1929, at Calshot, Supermarine won again in the Supermarine S.6 with the new Rolls-Royce R engine with an average speed of 528.89 km/h (328.64 mph).[5]^:244 Both Britain and Italy entered two new aircraft and a backup plane from the previous race. Three of the four new aircraft were disqualified (Supermarine S.6 N.248) or failed to finish the course (both Macchi M.67s), with the older Macchi M.52R taking second and Supermarine S.5 taking third.[17] Although France had ordered racing seaplanes from Bernard and Nieuport-Delage in 1928, they were unable to complete them in time for the 1929 race.[3]

1931 Schneider Trophy team from the UK

In 1931 the British government withdrew support, but a private donation of £100,000 from the wealthy and ultra-patriotic Lucy, Lady Houston,[18] allowed Supermarine to compete. When the French and Italian teams dropped out, leaving no other competitors, the British team flew the course alone on 13 September and won the coveted Schneider Trophy outright, having beaten the time record from the 1929 competition. Reportedly half a million spectators lined the beachfronts. The Italian, French, and German entrants failed to ready their aircraft in time for the competition.[19] The remaining British team set both a new world speed record of 610 km/h (380 mph) and won the trophy outright with a third straight win.[5]^:245 The following days saw the winning Supermarine S.6B further break the world speed record twice, making it the first craft to break the 400 mph barrier on 29 September at an average speed of 655.8 km/h (407.5 mph).

Although the British team had secured the trophy for the UK permanently with the 1931 uncontested win, development of the other 1931 entrants continued. The proposed Italian entrant (the Macchi M.C.72) which had pulled out of the contest due to engine problems later went on to set two new world speed records. In April 1933 (over Lake Garda, in northern Italy) it set a record with a speed of 682.36 km/h (424.00 mph). Eighteen months later in the same venue, it broke the 700 km/h barrier with an average speed of 709.202 km/h (440.678 mph). Both times the plane was piloted by Francesco Agello. This speed remains the fastest speed ever attained by a piston-engined seaplane.[20]

For a complete list of the aircraft which competed in the competitions, see Schneider Trophy aircraft.

• Reginald J. Mitchell, designer of the winning Supermarine Schneider Trophy entrants, also designed the Supermarine Spitfire.
• Mario Castoldi, designer of the 1926 winner, the Macchi M.39, also designed other contestants such as the M.52, the M.52R, the M.67, and the M.C.72. After the M.C.72 Castoldi designed some of the Italian fighters which flew during World War II, such as the MC.202.
• James Doolittle, winning pilot of the 1925 race, was accomplished in many other areas. He led the famous "Doolittle Raid", an American bombing attack on several Japanese homeland targets in April 1942.

In 1981 the race was revived, in name if not in concept, by the Royal Aero Club of Great Britain to commemorate the 50th anniversary of Britain's ultimate retention of the Schneider Trophy. The original trophy remained in the Science Museum, and a full-size replica was cast and the race opened on a handicapped basis to any propeller–driven landplane capable of maintaining 100 miles per hour (160 km/h; 87 kn) in straight and level flight, and weighing up to 12,500 lb (5,700 kg). Pilots had to have a minimum of 100 hours as pilot-in-command, and a valid air racing licence.

Following that event, the UK subsidiary of US computer company Digital Equipment Corporation (DEC) independently decided to sponsor a long-term revival of the Schneider Trophy, with the first race held in 1984. The idea was submitted by DEC's then UK PR consultancy Infopress as part of a broader commercial sponsorship programme designed to increase DEC's presence in the UK market at that time. DEC sponsored this revived race series from 1984 until 1991, which also marked the diamond jubilee of the final race in the original series. DEC and Infopress turned to the expertise of the Royal Aero Club's Records, Racing & Rally Association which again administered and ran the actual races. The 1981 Solent course, itself a close approximation of the original 1929 and 1931 Schneider Trophy courses over the Solent, was also used and adapted from year to year.

This sponsorship had a profound effect on the awareness and popularity of handicapped air racing in the UK and further afield, as well as markedly increasing DEC's commercial profile in the UK. The appeal of the race, its historic connections, and the fact that prize money was now on offer, meant that the entry list for the race was large enough to warrant the introduction of heats from 1985 onwards. (The 1984 race field was 62 entrants, believed at the time to be the largest-ever in all forms of air racing.)

The event received further boosts in 1986, when it was started by HRH Prince Andrew and his then fiancée Sarah Ferguson; in 1987, when the event was featured as one episode in a BBC television documentary series; and in 1988, when it was a central part of that year's ITV Telethon Appeal.

DEC invited customers and partners to each year's event as guests, and the general public watched in increasing numbers as the series grew in size and popularity.

For the pilots taking part, the event became, along with the King's Cup Race, the highlight of the UK's air racing season, and regularly attracted entrants from continental Europe.

DEC continued to sponsor the races through 1991. Since that time, the race has been run by the Royal Aero Club Records Racing and Rally Association along with the King's Cup and the British air racing championship. The venue has varied but is still flown on most occasions around a Solent-based course, usually around September of each year.
