13 September 1985: Major Wilbert D. Pearson, U.S. Air Force, flying McDonnell Douglas F-15A-17-MC, 76-0084, Celestial Eagle, launched an anti-satellite missile in a test, approximately 200 miles (322 kilometers) west of Vandenberg Air Force Base, on the central coast of California.

From level flight at Mach 1.22, Major Pearson pulled into a 3.8 G zoom to a 65° angle of climb. On reaching 38,100 feet (11,613 meters) and having slowed to 0.934 Mach, the LTV ASM-135 missile was automatically launched. At 1:42 p.m. Pacific Daylight Time, the 30 pound (13.6 kilogram) kinetic interceptor collided with the Solwind P78-1 satellite at an altitude of 345 miles (555 kilometers) and a closing speed of 15,000 miles per hour (21,140 kilometers per hour).

Solwind P78-1 was an Orbiting Solar Observatory satellite built by Ball Aerospace & Technologies Corp., of Broomfield, Colorado. The satellite had been launched from Vandenburg Air Force Base, 24 February 1979, and was in an almost circular orbit. P78-1 weighed 1,870 pounds (848 kilograms). Degraded batteries had made the satellite difficult to work and it was planned to terminate the mission when it was selected as the target for the ASAT.

The ASM-135 was a three-stage guided missile using a Boeing AGM-69 Short Range Attack Missile (SRAM) as its first stage and an LTV Aerospace Altair 3 rocket as the second stage. The third stage was the homing vehicle, which used an infrared seeker to intercept the targeted satellite. This was not an explosive warhead. The satellite was destroyed by the energy of the very high speed impact. The ASM-135 is 18 feet (5.48 meters) long, 20 inches (50.8 centimeters) in diameter and weighs 2,600 pounds (1,180 kilograms).

This incident was used as a plot device in Tom Clancy’s speculative World War III novel, Red Storm Rising.

22 years later, Celestial Eagle was assigned to the 125th Fighter Wing, Florida Air National Guard, at Homestead Air Reserve Base, and was flown by General Pearson’s son, Captain Todd Pearson of the 390th Fighter Squadron, Idaho Air National Guard. F-15A-17-MC 76-0084 was placed in storage at Davis-Monthan Air Force Base, Tucson, Arizona, 19 August 2010.

13 September 1935: Flying his Hughes H-1 Special, NR258Y,  Howard Robard Hughes, Jr. set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course near Santa Ana, California. Making seven passes over the measured course, each in opposite directions, his average speed was 567.12 kilometers per hour (352.39 miles per hour).¹ This was 61.27 kilometers per hour (38.07 miles per hour) faster than the previous record, set by Raymond Delmotte, 25 December 1934, flying a Caudron C.460 Rafale

The Los Angeles Times reported:

HUGHES WINS SKY RECORD AND CRASHES

Death Escaped in Mishap

Millionaire Flyer Forced Down After Averaging 347 Miles and Hour

     Howard Hughes, Millionaire sport flyer, missed death by a narrow margin yesterday morning a few seconds after he brought back to the United States the world’s speed mark for land planes when he averaged 347 miles an hour near Santa Ana.

Official confirmation of the new mark must await calibration of the speed over the measured three-kilometer course, bordering the Eddie Martin Airport, by the Federation Aeronautic Internationale of Paris, France. The figures are to be submitted following a conference between officials of the National Aeronautics Association and representatives of the California Institute of Technology.

TIMER CONFIDENT

     “I don’t expect any difficulty in having Hughes’s speed marks officially allowed,” said William R. Enyart, official timer, shortly after the mystery racing plane made a forced landing in a beet field and ploughed a furrow for sixty yards.

     Hughes had just completed his seventh lap against the former world record of 314.319 miles an hour, held by Raymond Delmotte of France, when he suddenly lifted the silver monoplane into the air as his fourteen-cylinder Wasp radial air-cooled engine sputtered.

     The pilot sought altitude, climbing to 500 feet. Then he turned and headed for the beet field, his engine stopped.

DEAD STICK LANDING

     Despite his landing speed of about eighty miles and hour, Hughes made a perfect “dead stick” landing as the ship flattened out on its lower side and slid through the soft ground. A bent propeller and wrenched landing gear were the only visible damage.

     “My gas supply in one tank was exhausted,” Hughes said as he stepped unhurt from the racer. When I switched on the other tank the motor didn’t take it. An air lock—pressure built up from the dry tank—had developed in the line and the only thing I could do was attempt a forced landing.”

WINS CONGRATULATIONS

     Hughes received the congratulations of numerous officials gathered to witness the assault on the speed record for his manipulation of the speedy ship and the perfect landing. Amelia Earhart, who had been flying as an observer, was one of the first to praise the pilot.

     “The stoppage in gas came so suddenly, Hughes said, “that I did not have time to lower the retractable landing gear. It was only partially down when the plane hit. The force drove it back into the ship and probably aided in preventing additional damage.”

SERIES OF CHECKS

     Six record-breaking tests were made as Hughes streaked over the course. An electronic chronograph photographed and clocked each flight. Four are required to officially set a new speed mark.

     Determination of Hughes to make his second record-breaking attempt early yesterday morning came as a surprise and after he and his assistants had spent the night checking over difficulties faced in the flight late Thursday afternoon.

     Hughes rolled his $120,000, 1000-horsepower, low-winged monoplane from the hangar at Union Air Terminal shortly after daylight and awaited word from officials at the measured course that all was in readiness.

     At 6:30 a.m. he flashed into the air and an hour and ten minutes later had made his successful seven flight when halted by the gas supply stoppage.

     Hughes and associates announced that the next speed record he will attempt to break in his specially constructed racer will be the flight from Los Angeles to New York. The present time, 10 hours and 2 minutes, is held by Col. Roscoe Turner.

SCENE OF FLIGHT

     The record-breaking flight was made over the course on the Irvine ranch surveyed for the late Dr. Albert A. Michelson’s experiments to measure the speed of light. Joe Nikrent and W.H. Hitchman, representing the National Aeronautic Association, helped time the dashes.

     In beating the Delmotte record by approximately twenty-nine miles an hour, Hughes brings back to America, the record once held by the late James Wedell. Wedell set a world mark of490.8 kilometers an hour, only to have it bettered by the French flyer last December 24.

The Hughes H-1 (Federal Aviation Administration records identify the airplane as the Hughes Model 1B, serial number 1) was a single-seat, single-engine low-wing monoplane with retractable landing gear. Emphasis had been placed on an aerodynamically clean design and featured flush riveting on the aluminum skin of the fuselage. The airplane was 27 feet, 0 inches long (8.230 meters) with a wingspan of 25 feet (7.6 meters) and height of 8 feet (2.438 meters). (A second set of wings with a span of 31 feet, 9 inches (9.677 meters) was used on Hughes’ transcontinental flight, 19 January 1937). The H-1 has an empty weight of 3,565 pounds (1,617 kilograms) and gross weight of 5,492 pounds (2,491 kilograms).

The H-1 was powered by a air-cooled, supercharged 1,534.943-cubic-inch-displacement (25.153 liter) Pratt & Whitney Twin Wasp Jr. two-row, fourteen-cylinder radial engine. Pratt & Whitney produced 18 civil and 22 military (R-1535) versions of the Twin Wasp Jr., in both direct-drive and geared configurations, rated from 650 to 950 horsepower. According to a 1937 article in Popular Mechanics,

“Hughes’ motor is a stock air-cooled fourteen-cylinder twin-row Pratt & Whitney wasp junior that develops 700 horsepower at 2,500 revolutions per minute at 8,500 feet altitude. The engine has an outside diameter of forty-four and one-eighths inches, a dry weight of 1,060 pounds, and a displacement of 1,535 cubic inches. Compression ratio is 6.7 to one and the supercharger ratio is ten to one. Carburetion and magneto ignition are stock.”

Popular Mechanics Magazine, Vol. 67, No. 4, April 1937, at Page 502, Column 2

The data cited by Popular Mechanics seems to match the characteristics of P&W’s Twin Wasp Jr. S3A5-G aircraft engine.

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)

Lap 5: 546.5 kilometers per hour (339.6 miles per hour)

Lap 6: 546.1 kilometers per hour (339.4 miles per hour)

Lap 7: 543.5 kilometers per hour (337.7 miles per hour)

Overall average speed: 547.3 kilometers per hour (340.08 miles per hour)

Air Ministry,

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.

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).

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

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.

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

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.

John Nelson Boothman was born at Harrow, northwest London, England, 19 February 1901. He was the son of Thomas John Boothman, a railway clerk, and Mary Burgess Boothman. He  became interested in aviation while very young, and took his first flight at the age of 10, as a passenger of Samuel Franklin Cody, the first pilot to fly a powered airplane in England.

Boothman was educated at Harrow High School. In 1918, when he was 16 years old, Boothman volunteered as a driver with the Croix-Rouge française (French Red Cross), serving in the Balkans until World War I came to an end. He was awarded the Croix de Guerre.

On his return to England, he took flying lessons and joined the Royal Air Force. He received a short-service commission as a Pilot Officer (probationary), 29 March 1921. He trained at No. 1 Flight Training School. He then joined No. 4 Squadron at Constantinople. On 22 March 1922, Boothman was confirmed in the rank of Pilot Officer. He was promoted to Flying Officer 29 September 1922.

Also in 1922, Pilot Officer Boothman married Miss Gertrude Andrews. They would have one son.

Flying Officer Boothman returned to England in 1924 and was assigned as a flight instructor at the Central Flying School. He was also a member of an aerial demonstration team.

After five years of service, on 1 January 1926 Boothman’s commission as a Flying Officer, Royal Air Force, was made permanent. He returned to the Middle East, joining No. 55 Squadron in Iraq, 21 September 1926. This was a bombing squadron, equipped with the de havilland DH-9A. Boothman was promoted to Flight-Lieutenant 1 July 1927. He served with the Air Staff before going on to No. 30 Squadron, which also flew DH-9As, as a flight commander, 24 February 1928.
