13 November 1926: The 1926 race for the Coupe d’Aviation Maritime Jacques Schneider (the Schneider Trophy) was held at Hampton Roads, a large natural harbor between southeastern Virginia and northeastern North Carolina, two states on the Atlantic coast of the United States. There were an estimated 30,000 spectators. The race consisted of seven laps of a 50 kilometer (31 miles) triangular course.

The location of each race went to the country whose national team had won the previous year. Lieutenant James H. Doolittle, Air Service, United States Army, had won the 26 October 1925 race at Baltimore, Maryland, flying a Curtiss R3C-2 to an average speed of 232.57 miles per hour (374.29 kilometers per hour).

The 1926 Schneider Race included three Italian and three American airplanes. The British team’s aircraft were not ready so they did not compete.

All three Regia Aeronautica pilots, Major Mario de Bernardi, Captain Arturo Ferrarin, and Lieutenant Adriano Bacula, flew Macchi M.39 seaplanes, powered by the Fiat AS.2 V-12 engine.

The American team used three different Curtiss biplanes, each with a different Curtiss V-12 engine. 1st Lieutenant Christian Frank Schilt, United States Marine Corps, flew a Curtiss R3C-2, serial number A.7054, carrying race number 6. Schilt’s airplane was powered by a Curtiss V-1400. Lieutenant William Gosnell Tomlinson, U.S. Navy, flew a Curtiss F6C-3 Hawk, A.7128, with race number 2. This airplane was equipped with a Curtiss D-12A. Lieutenant George T. Cuddihy, U.S. Navy, flew a Curtiss R3C-4, A.6979, with race number 4, with a Curtiss V-1550.

The race was delayed for two days because of adverse weather conditions. The race began at 2:35 p.m. on Saturday afternoon, with the first of three Italian racers entering the course.  Airplanes departed at intervals to avoid coming too close to each other while flying the course.

De Bernardi finished the seven laps in 52 minutes, 56.22 seconds, averaging 246.496 miles per hour (396.697 kilometers per hour). Schilt finished in second place in 56 minutes, 23.96 seconds, at 231.364 miles per hour (372.344 kilometers per hour). Bacula was third at 59 minutes, 51.31 seconds, at 218.006 miles per hour (350.847 kilometers per hour). Fourth place went to Tomlinson, completing the course in 1 hour, 35 minutes, 16.72 seconds, at 136.954 miles per hour (220.406 kilometers per hour). Ferrarin’s airplane had an oil line break and he made a precautionary landing at the end of his fourth lap. A fuel pump on Cuddihy’s airplane failed, and his engine stopped. He touched down short of the finish line on his seventh and final lap.

The Macchi M.39 racing float plane was designed by Mario Castoldi. It is a single engine, single-place, low-wing monoplane with two pontoons, or floats. The wing is externally braced, has 0° dihedral, and incorporates surface radiators. The M.39 is 6.473 meters (22 feet, 2.8 inches) long with a wingspan of 9.26 meters (30 feet, 4.6 inches) and height of 3.06 meters (10 feet, 0.5 inches). The empty weight of the Schneider Trophy racer is 1,300 kilograms (2,866 pounds) and its maximum gross weight is 1,615 kilograms (3,560 pounds).

The M.39 is powered by a water-cooled, normally-aspirated, 31.403 liter (1,916.329 cubic inch) Fiat AS.2 DOHC 60° V-12 direct-drive engine with a compression ratio of 6:1. It used three carburetors and two magnetos, and produced 882 horsepower at 2,500 r.p.m. The engine drove a two-bladed, fixed-pitch metal propeller designed by Dr. Sylvanus A. Reed. The AS.2 engine was designed by Tranquillo Zerbi, based on the Curtiss Aeroplane and Motor Company’s D-12 engine. The engine was 1.864 meters (6 feet, 1.4 inches) long, 0.720 meters (2 feet, 4.4 inches) wide and 0.948 meters (3 feet, 1.3 inches) high. It weighed 412 kilograms (908 pounds).

The Macchi M.39 could reach 420 kilometers per hour (261 miles per hour).

Macchi M.39 MM.76 is in the collection of the Aeronautica Militare museum.

He set several world aviation records and continued his work as a test pilot. He died in 1959 at the age of 65 years.

Adriano Bacula also set several world records. He was killed in an airplane crash in Slovenia, 18 April 1938.

Arturo Ferrarin, another world record holder, was killed while testing an experimental airplane, 18 July 1941.

Christian Frank Schilt enlisted as a private in the U.S. Marine Corps in 1917. He was awarded the Medal of Honor for his actions in Nicaragua, 6–8 January 1928. During World War II, Schilt served as Commander, Marine Air Group 11 during the Solomons Campaign, and later went on to command Aircraft, Fleet Marine Force, Pacific.

23 June 1924: Lieutenant Russell Lowell Maughan, Air Service, United States Army, took off from Mitchel Field, Long Island, New York, at 3:58 a.m., Eastern Time, and flew across the country to land at Crissy Field, at the Presidio of San Francisco, California at 9:46 p.m., Pacific Time. He covered a distance of 2,670 miles (4,297 kilometers) in 21 hours, 47 minutes. Maughan’s actual flight time was 20 hours, 48 minutes. He averaged 128.37 miles per hour (206.59 kilometers per hour).

His Dawn-To-Dusk transcontinental flight took place on a mid-summer day in order to take advantage of the longer hours of daylight, and he flew from East to West, to follow the advancing Sun across the sky.

Lieutenant Maughan made stops at McCook Field, Dayton, Ohio; St. Joseph, Missouri; North Platte, Nebraska; Cheyenne, Wyoming and Salduro Siding, Utah. The stop at Dayton took 1 hour, 20 minutes when a mechanic over-tightened a fuel line fitting and damaged it. When he arrived at “Saint Joe,” the grass field was wet from rains, restricting his takeoff weight. Unable to carry a full load of fuel, he took off with a reduced load and then made a previously unplanned stop at North Platte, Nebraska, where he topped off his fuel tank.

Russell Maughan was an experienced combat pilot and test pilot. He had been awarded the Distinguished Service Cross for his actions during World War I, and he had competed in numerous air races and had set several speed records.

The airplane flown by Lieutenant Maughan was the fourth production Curtiss PW-8 Hawk, a single-place, single-engine biplane fighter, serial number A.S. 24-204. It was modified by the Curtiss Aeroplane and Motor Company at its Long Island, New York, factory. Curtiss removed the fighters’s two .30-caliber machine guns and added 100 gallons (378.5 liters) to the airplane’s standard fuel capacity of 77 gallons (291.5 liters).

The Curtiss PW-8 Hawk was powered by a water-cooled, normally-aspirated 1,145.111-cubic-inch-displacement (18.765 liter) Curtiss D-12 dual overhead cam (DOHC) 60° V-12 engine, which was developed by Arthur Nutt, based on the earlier Curtiss K-12 which had been designed by Charles B. Kirkham. The D-12 had four valves per cylinder and a compression ratio of 5.7:1. It was rated at 415 horsepower at 2,000 r.p.m., and 460 horsepower at 2,300 r.p.m. During testing, it produced a 475 horsepower at 2,320 r.p.m. using a 50/50 mixture of 95-octane gasoline and benzol. The D-12 was a right-hand tractor direct-drive engine. It turned a two-bladed, fixed-pitch, forged aluminum propeller designed by Dr. Sylvanus A. Reed. The Curtiss D-12 was 56¾ inches (1.441 meters) long, 28¼ inches (0.718 meters) wide and 34¾ inches (0.882 meters) high. It weighed 678.25 pounds (307.65 kilograms).

The PW-8 had a cruise speed of 136 miles per hour (219 kilometers per hour) and maximum speed of 171 miles per hour (275 kilometers per hour) at Sea Level. The airplane’s service ceiling was 20,350 feet (6,203 meters) and its range was 544 miles (875 kilometers).

In the early years of military aviation, pilots undertook various dramatic flights to create public awareness of the capabilities military aircraft. Of this transcontinental flight, Maughan said, “The real reason for my flight across the United States in the sunlight hours of one day was that the chief of the Air Service wanted to show Congress just how unprotected are the people of the Pacific Coast.”

Curtiss PW-8 Hawk A.S. 24-204 was damaged beyond repair at Selfridge Field, Michigan, 11 May 1926.
