13 September 1931: Having won the previous two Coupe d’Aviation Maritime Jacques Schneider international seaplane races, the United Kingdom was in the position of permanently winning the famous Schneider Trophy if it were to win a third consecutive race.

The 1931 race was the twelfth in a series of annual or semiannual races which were first held in 1913, specifically for seaplanes. Teams from several nations, France, Great Britain, Italy and the United States, competed with float-equipped airplanes built specifically for the races. The national team which won three consecutive races would win the series and take home the Trophy. Italy had won three times (1920, 1921, and 1926); the United States, twice (1923, 1925); and France, one time (1913). The United Kingdom had previously won in 1922, 1927 and 1929.

Having won the race in 1929, Great Britain was the host nation for 1931. Like the 1929 race, the 1931 race was held over The Solent, a body of water between the harbor city of Portsmouth, England, and the Isle of Wight. Instead of the four-sided polygon used previously, the 1931 race course was a triangle of 50 kilometers (31.07 statute miles). Competitors would make seven circuits of the course, with all left-hand turns, for a total distance of 350 kilometers (217.48 statute miles).

Competitors would fly seven counter-clockwise laps of the 50-kilometer triangular race course (FLIGHT)

Italy had been developing the Macchi-Castoldi M.C. 72 with its 3,100-horsepower, 24-cylinder Fiat AS.6 engine, but the airplane was not ready by the required date. The United States was unwilling to invest the required money and had not entered since the 1927 race. France also was not prepared to compete. Both France and Italy formally announced their intention not to compete on 4 September 1931.

This meant that only a single British airplane was required to complete the race course to win the race and permanent possession of the trophy. Three airplanes were ready, one Supermarine S.6 and two new S.6Bs.

Postponed because of rain and fog on the previous day, the 1931 race started at 1:02:10 p.m., Sunday, 13 September, with the firing of the starting gun from HMS Medea. Flight-Lieutenant John Nelson Boothman, Royal Air Force, in a blue and silver Supermarine S.6B, number S.1565, taxied across the start line at 1:10:19 p.m.

Race rules required that competitors take off, circle and land on the water. They were then required to taxi on the water for two minutes, before taking off a second time to begin the officially timed race laps. Observers reported that Flight-Lieutenant Boothman’s performance of the preliminary test was flawless. He taxied into position for his second takeoff and was airborne with a 40 second run.

Boothman’s lap times were:

Lap 1: 552.15 kilometers per hour (343.1 miles per hour)

Lap 2: 551.5 kilometers per hour (342.7 miles per hour)

Lap 3: 547.1 kilometers per hour (340.0 miles per hour)

Lap 4: 544.5 kilometers per hour (338.3 miles per hour)

ROYAL AIR FORCE.

     The KING has been graciously pleased to approve of the award of the Air Force Cross to the undermentioned officers of the Royal Air Force:—

Flight Lieutenant John Nelson Boothman.

In recognition of his achievement in winning the Schneider Trophy Contest, 1931.

Supermarine S.6B, S.1596. (BAE Systems)

S.1595 was Vickers-Supermarine S.6B Monoplane, designed by Reginald Joseph Mitchell, who would later design the legendary Supermarine Spitfire fighter of World War II. The racer was developed from Mitchell’s earlier S.4, S.5 and S.6 Schneider Cup racers, and was built at the Supermarine Aviation Works (Vickers), Ltd., Southampton, on the south coast of England. There were two S.6Bs, with the second identified as S.1596.

Reginald Joseph Mitchell, C.B.E., F.R.Ae.S.

The Supermarine S.6B was a single-place, single-engine, low-wing monoplane with two fixed pontoons as an undercarriage. It was of all-metal construction and used a high percentage of duralumin, a very hard alloy of aluminum and copper, as well as other elements. The float plane was 28 feet, 10 inches (8.788 meters) long, with a wingspan of 30 feet, 0 inches (9.144 meters) and height of 12 feet, 3 inches (3.734 meters). The wing area was 145 square feet (13,5 square meters). The S.6B had an empty weight of 4,560 pounds (2,068 kilograms) and gross weight of 5,995 pounds (2,719 kilograms).

In an effort to achieve the maximum possible speed, aerodynamic drag was eliminated wherever possible. There were no radiator or oil cooler intakes. The wing surfaces were constructed of two thin layers of duralumin with a very small space between them. The engine coolant, a mixture of water and ethylene glycol, was circulated between these layers, which are known as surface radiators. The engine had a high oil consumption rate and the vertical fin was the oil supply tank. The skin panels also served as surface radiators. The fuselage panels were corrugated for strength, and several small parallel passages transferred lubricating oil from the fin tank to the engine, and further cooled the oil.

S.1595 was powered by a liquid-cooled, supercharged, 2,239.327-cubic-inch-displacement (36.696 liter) Rolls-Royce Type R single-overhead-camshaft (SOHC) 60° V-12 engine, number R29. The Type R was a racing engine with 4 valves per cylinder and a compression ration of 6:1. In the 1931 configuration, it produced 2,350 horsepower at 3,200 r.p.m. It used a 0.605:1 reduction gear and turned a Fairey Aviation fixed-pitch airscrew with a diameter of 8 feet, 6 inches (2.591 meters). A special fuel, a mixture of benzol, methanol and acetone with TCP anti-detonation additive, was used.

There would have been no 1931 British Schneider Trophy Race team without the generous contribution of Lucy, Lady Houston, D.B.E., who donated £100,000 to Supermarine to finance the new aircraft. Lady Houston would later sponsor the 1933 Houston Mount Everest Flying Expedition.

The winning aircraft, S.1595, is in the collection of the Science Museum, London.

3 April 1933: Lord Clydesdale—at the time, the youngest Squadron Leader in the Royal Air Force and in command of 602 Squadron—as Chief Pilot of the Houston Mount Everest Flying Expedition—flew a modified Westland PV-3 biplane, G-ACAZ, in formation with Westland PV-6, G-ACBR, over the summit of Mount Everest, the world’s highest mountain, elevation 29,029 feet (8,848 meters). The PV-6 was piloted by Flight Lieutenant David Fowler McIntyre, also of 602 Squadron. The two airplanes took off from Purnia, in the northeast of India, at 8:25 a.m., and returned three hours later.

Aboard Lord Clydesdale’s airplane was observer Lieutenant Colonel Latham Valentine Stewart Blacker OBE (“Blacker of the Guides”), and on McIntyre’s was Sidney R. G. Bonnett, a cinematographer for Gaumont British News. During the ascent to Everest, Bonnett damaged his oxygen hose and lost consciousness due to hypoxia.

The Bristol Pegasus S.3 was considered to be the only aircraft engine in the world that would be capable of powering an airplane with the necessary personnel and equipment high enough to fly over Everest. It was an air-cooled, supercharged, 1,752.79-cubic-inch-displacement (28.72 liter) nine-cylinder radial engine, with a compression ratio of 5.3:1. It had a Normal Power rating of 525 horsepower at 2,000 r.p.m. at 11,000 feet (3,353 meters), and produced a maximum of 575 horsepower at 2,300 r.p.m. at 13,000 feet (3,962 meters). It had a Takeoff Power rating of 500 horsepower at 2,000 r.p.m. at Sea Level, with a three minute limit. The engine drove a two-bladed, fixed-pitch wooden propeller manufactured by The Airscrew Company Ltd., through either a 0.5:1 or 0.655:1 gear reduction.

After deciding on the engine, the Expedition had to select an airplane. The Westland PV-3 was chosen because it had the highest rate of climb of any airplane ever tested by the Royal Air Force.

The Westland Aircraft Works PV-3 was a private venture prototype torpedo bomber, based on the earlier Westland Wapiti. It had an all-metal structure and folding wings. Only one was built, and no orders for the airplane were placed. The airplane was modified for the Houston Everest Expedition. The gunner’s open position behind the pilot’s cockpit was replaced with an enclosed cabin for an observer and cameras. The original Bristol Jupiter X.FA engine was replaced by the more powerful Bristol Pegasus S.3 and a large-diameter propeller.

The Houston-Westland was 34 feet, 2 inches (10.414 meters) long with a wingspan of 46 feet, 6 inches (14.173 meters) and overall height of 11 feet, 8 inches (3.556 meters). The airplane had an empty weight of 3,420 pounds (1,551.3 kilograms) and loaded weight of 5,100 pounds (2,313.3 kilograms).

The PV-3 had a maximum speed of 163 miles per hour (262.3 kilometers per hour) and a service ceiling of 35,000 feet (10,668 meters). Burmah-Shell provided a special fuel for operations at very high altitude.

Westland PV-6 G-ACBR

The Westland PV-6 was also a private venture prototype. It was later converted to the Wallace I configuration.

The airplanes carried Williamson Automatic Eagle III survey cameras that would take photographs of the surface at specific intervals as the airplanes flew over known survey locations. It was planned that a photographic mosaic of the terrain and an accurate map could be drawn.

The expedition was financed by Lucy, Lady Houston, DBE, who offered to provide up to £15,000 to finance the project. The flight helped to demonstrate the need for specialized equipment for high altitude flight.

For his accomplishment, Lord Clydesdale—later, Air Commodore His Grace The Duke of Hamilton KT GCVO AFC PC DL FRCSE FRGS—was awarded the Air Force Cross.

Mount Everest, known in Nepal as सगरमाथा (Sagarmāthā), is a mountain in the Mahalangur Range of the the Himalayas. Its peak is believed to be the highest point on Earth. The mountain was “discovered” by the Western world in 1856, during the decades-long Great Trigonometrical Survey of India. Identified as Peak XV, the height of the mountain was measured at 29,002 feet¹ (8,839.8 meters) above Sea Level. The Royal Geographical Society named the mountain Everest after Colonel Sir George Everest, FRS, FRAS, the Surveyor General of India from 1830 to 1843. At present, the agreed height of Everest is 8,848 meters (29,029 feet). The upper portion of the mountain is primarily marble and is covered by several meters of ice and snow.

¹ Interestingly, in The Map Makers (John Noble Wilford, Alfred A. Knopf, New York, 1981), it was reported that the Great Survey actually calculated the height of the mountain at 29,000 feet (8,839.2 meters), but it was felt that this value would be taken as an approximation rather than an exact value, so 2 feet were added, resulting in the generally known height of 29,002 feet (8,839.8 meters).
