A Sikorsky S-76A in flight over the City of New York. (Sikorsky, a Lockheed Martin Company)
4–9 February 1982: Sikorsky test pilots Nicholas D. Lappos, William Frederick Kramer, Byron Graham, Jr., David R. Wright, and Thomas F. Doyle, Jr., set a series of Fédération Aéronautique Internationale (FAI) speed, time-to-climb and sustained altitude world records while flying a Sikorsky S-76A helicopter, serial number 760178, FAA registration N5445J, at Palm Beach, Florida.
On 4 February, Nick Lappos, who had made the first flight with the prototype S-76 nearly five years earlier, set a record of 335,50 kilometers per hour (208.47 miles per hour) over a 3-kilometer course (FAI Record File Number 1261, Class E-1d), and 342,61 km/h (212.89 m,p,h.) over a straight 15/25 kilometer course (1262). Flying in the E-1e class for heavier helicopters, Billy Kramer ¹ flew both the 3 kilometer and 15/25 kilometer course at an average 340,48 km/h (211.56 m.p.h.) (1828, 1829).
On 5 February, Byron Graham, Jr.,² flew the S-76A to 3,000 meters (9,843 feet) in 3 minutes, 11 seconds (1819); to 6,000 meters (19,685 feet) in 8 minutes, 37.3 seconds (Class E-1d, 1821); and a sustained altitude of 7,940 meters (26,050 feet) in level flight (Class E-1D, 9947).
On 6 February, David R. Wright averaged 331,22 km/h (205.81 m.p.h.) over a 100 kilometer closed circuit without payload (Class E-1d, 1264), and 334,69 kilometers per hour (207.97 m.p.h.) over a closed circuit of 100 kilometers without payload (Class E-1e, 1265).
After taking a day off, the Sikorsky S-76A was back in the air on 8 February, this time with Thomas F. Doyle, Jr., flying the helicopter over the 500 kilometer closed circuit, without payload. The Sikorsky averaged 345,74 km/h (214.83 m.p.h.) (Class E-1, 1844, E-1e, 1845). This was also an Absolute World Speed Record for helicopters (Class E, 11660).
On the last day of the series, 9 February 1982, David R. Wright was back in the cockpit of N5445J. Flying the 1,000 kilometer closed circuit without payload, the S-76A averaged 305, 10 km/h (189.58 m.p.h.) (Class E-1e, 1827).
After 41 years, nine of these twelve Fédération Aéronautique Internationale world records still stand.

N5445J was owned by Rodgers Helicopter Service, Kearney, Nebraska, and operated as an air ambulance by Good Samaritan AirCare until its U.S. registration was cancelled, 10 July 2006.
Fire-damaged Sikorsky S-76A, serial number 760178, registration PR-IME, at Macaé Airport, Rio de Janeiro, Brasil, 29 December 2008.
The record-setting helicopter eventually found its way to Rio de Janeiro, Brazil. Owned and operated by Atlas Taxi Aereo, 760178 had been re-registered as PR-IME and was transporting Petrobras employees to offshore oil production platforms.
At approximately 8:30 a.m., 29 December 2008, PR-IME had departed Macaé Airport enroute Platform P-12 in the Campos Basin with 7 persons on board.
Shortly after takeoff, the flight crew observed an AC generator caution light and returned to the airport. Before landing, a fire warning light also illuminated. Upon landing on Runway 24, all seven escaped from the burning helicopter without injury. The fire was quickly extinguished, but the Sikorsky S-76A was substantially damaged.

The Sikorsky S-76A is a twin-engine intermediate class helicopter that can be configured to carry 6 to 12 passengers. It is used as an executive transport, a scheduled passenger airliner, utility transport, search and rescue aircraft and air ambulance. The helicopter is certified for instrument flight and has retractable tricycle landing gear.
The prototype was rolled out at Stratford, Connecticut on 11 January 1977 and the first flight took place on 13 March. It was certified in 1978 and the first production aircraft was delivered to Air Logistics, 27 February 1979.
The number 2 Sikorsky S-76 makes the type’s first flight, 13 March 1977. (Sikorsky Historical Archives)
The S-76A is 52 feet, 6 inches (16.00 meters) long with rotors turning. The fuselage has a length of 43 feet, 4.43 inches (13.219 meters) and a width of 8 feet (2.44 meters). The helicopter’s overall height is 14 feet, 5.8 inches (4.414 meters). The four bladed composite main rotor is 44 feet (13.41 meters) in diameter. The blades are attached to a one-piece forged aluminum hub and use elastomeric bearings. As is customary with American helicopters, the main rotor turns counter-clockwise as seen from above. (The advancing blade is on the right.) The four-bladed tail rotor has a diameter of 8 feet (2.438 meters) and turns clockwise as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.) It is mounted in a pusher configuration on the left side of the tailboom. The tail rotor is constructed of composite airfoils mounted to graphite spars.
The S-76A was equipped with two Allison 250-C30 turboshaft engines rated at 557 shaft horsepower, each. Subsequent variants have been built with Turbomeca Arriel 1S and 2S engines, as well as Pratt & Whitney PT6B-3A and PW210S engines.
The S-76 has an empty weight of 7,007 pounds (3,178 kilograms). The S-76A maximum gross weight was 10,500 pounds (4,763 kilograms). Beginning with the S-67B, this was increased to 11,700 pounds (5,307 kilograms).
The Sikorsky S-76 has a maximum cruise speed of 155 knots (287 kilometers per hour). It can hover in ground effect (HIGE) at 7,050 feet (2,149 meters) or out of ground effect (HOGE) at 3,300 feet (1,006 meters). The service ceiling is 13,800 feet (4,206 meters).
The helicopter was designed with offshore oil support as a major consideration. It was intended to carry 2 pilots and 12 passengers 400 nautical miles (460 statute miles, or 741 kilometers). Maximum range with no reserve is 411 nautical miles (473 statute miles/762 kilometers).
Sikorsky built 307 S-76As. More than 850 of all variants have been built. The current production model is the S-76D.

Kuhrt, a former Sikorsky president; William F. Gilson; and Richard C. Elpel. The aircraft had been flying a group associated with King Hussein of Jordan. At the time, sabotage was considered a possibility. The NTSB investigation was unable to determine a probable cause.

Avro Canada CF-100 Mark 1, 18101 (Avro Canada, via Harold A. Skaarup)
19 January 1950: At Malton Airport,¹ northwest of Toronto, Ontario, Canada, the Gloster Aircraft Company’s chief test pilot, Squadron Leader William Arthur Waterton, AFC and Bar, GM, took the prototype Avro Canada CF-100 Mark 1, serial number 18101, for its first flight. Waterton, a Canadian, had been loaned to Avro Canada by Gloster for the test flight. (Avro Canada and Gloster were both owned by the Hawker Siddeley Group. Waterton was the most experienced jet aircraft pilot in the group at the time.)
The first flight lasted approximately 40 minutes, reaching 180 knots (207 miles per hour/333 kilometers per hour) and 5,000 feet (1524 meters). The only problem was that the button for cycling the landing gear would not operate, so Waterton decided to continue the flight with the gear down.² After landing Waterton said,
“She handled extremely well. Avro Canada seems to have overcome many points of criticism in existing fighters.”
The trouble had been simple. The shock-absorbing undercarriage legs were British developed and, unknown to the makers, were contracting slightly in the cold. Consequently, when the ‘plane’s weight came off the wheels, the legs did not “stretch” as much as they should have done—there was insufficient “stretch” to release the electrically triggered safety switch. When modifications were made the undercarriage gave no further trouble.

Avro Canada CF-101 Mark 1 18101 with government officials and test pilot Bill Waterton (Library and Archives Canada, MIKAN No. 4047130/Neil Corbett, Test & Research Pilots, Flight Test Engineers)
CF-100 18101 was the first of two Mark 1 prototypes for a twin-engine, all-weather, long range fighter. It had originally been designated XC-100. It was a large two-place aircraft, with a low, straight wing and a high-mounted horizontal stabilizer. It had tricycle landing gear. Each strut mounted two tires to support the weight of the aircraft. The two engines were mounted in long nacelles above the wings and on either side of the fuselage.
The CF-100 Mark 1 prototypes were 52 feet, 6 inches (16.002 meters) long, with a wing span of 52 feet, 0 inches (15.850 meters) and overall height of 14 feet, 6.4 inches (4.430 meters). They had an empty weight of 19,185 pounds (8,702 kilograms), and gross weight of 31,877 pounds (14,459 kilograms).
The prototypes were powered by two Rolls-Royce Avon RA.2 turbojet engines. (Some sources say the engines were RA.3s, though a specific mark is not described.) The Avon R.A.2 was a single-spool, axial flow turbojet with a 12-stage compressor section and single-stage turbine. It was rated at 6,000 pounds of thrust (26.69 kilonewtons). The RA.2 weighed 2,400 pounds (1,089 kilograms). The RA.2 also powered the English Electric Canberra B.1 prototype. Production CF-100s would be powered by the Avro Canada Orenda engine.
The Mark 1 had a maximum speed of 552 miles per hour (888 kilometers per hour) at 40,000 feet (12,192 meters). It could climb at 9,800 feet per minute (49.8 meters per second). Its service ceiling was 50,000 feet (15,240 meters).
The two Mark 1s had no radar and were not armed.

Following the two Mark 1 prototypes, Avro Canada produced ten Mark 2 pre-production aircraft, two of which were trainers. The first operational variant was the CF-100 Mark 3. It was equipped with radar and armed with eight Browning M3 .50-caliber machine guns with 200 rounds of ammunition per gun.
The Mark 4 was equipped with a more powerful radar. In addition to the machine guns, armament consisted of 58 unguided 2.75 inch (70 millimeter) Mark 4 Folding Fin Aerial Rockets (FFARs), each with a 6 pound 92.7 kilogram) explosive warhead. These were carried in wingtip pods.

On 18 Dec 1952, Avro Canada test pilot Janusz Żurakowski put CF-101 Mark 4 serial number 18112 into a dive from 30,000 feet (9,144 meters) and reached Mach 1.10. This was the first time that a straight wing aircraft exceeded Mach 1 without rocket power.
The majority of CF-100s were the Mark 5 variant. These had a greater wing span and larger horizontal stabilizer. The machine guns were eliminated.

A total of 692 of all types were built. 53 were sold to the Belgian Air Force. The CF-100 remained in service with the Royal Canadian Air Force until 1981.
CF-100 Mark 1 18102 was used to test wingtip-mounted fuel tanks. It crashed 5 April 1951 and was destroyed. Test pilot Flight Lieutenant Bruce Warren and flight engineer Jack Hieber were killed. The crew may have suffered hypoxia.
18101 was retained for testing. It was scrapped in 1965.

William Arthur Waterton was born 18 March 1916, at Edmonton, Alberta, Canada. He was the first of two sons of William Albert Waterton, a police officer, and Mary Elizabeth Sereda Waterton. After high school, he attended Camrose Normal School, Alberta, a college for teachers. He then spent two years the Royal Military College, Kingston, Ontario, graduating 1937. While there, he was a boxer. Waterton was commissioned in the 19th Alberta Dragoons in 1938.
Waterton crossed the Atlantic Ocean to attend the Civil Flying Training School, Hanworth, Feltham, Middlesex. He departed St. John, New Brunswick, aboard the 22,022 gross registered ton (62,322 cubic meters) Canadian Pacific passenger liner Duchess of Richmond, arriving at Liverpool on 17 April 1939.

On 10 June 1939, Bill Waterton was granted a short service commission in the Royal Air Force as an Acting Pilot Officer on probation for six years on the active list. (RAF serial number 42288)
Six months later,18 November 1939, Acting Pilot Officer on probation William Arthur Waterton was graded as Pilot Officer on probation.
A Hawker Hurricane Mk.I, N2320, assigned to No. 242 Squadron, Royal Air Force, circa 1940.
Pilot Officer Waterton was assigned to No. 242 Squadron, the first all-Canadian fighter squadron, at RAF Church Fenton, southeast of Tadcaster, North Yorkshire, England. The Second World War had been underway for twelve weeks.
On 25 May 1940 his Hawker Hurricane Mk.I ² (squadron code “LE”), was disabled by anti-aircraft fire over Dunkerque, France. Waterton made it across the English Channel to Dover where he crash landed, suffering a severe head injury. Waterton was unconscious in a London hospital for five days, and remained hospitalized for three months.
Waterton’s Hurricane was repaired and returned to service.
On 18 Nov 1940, Pilot Officer on probation Waterton was confirmed in his appointment and promoted to the rank of Flying Officer.
After returning to flight status, Flying Officer Waterton was assigned as a flight instructor with No. 6 Operational Training Unit (OTU).
Flying Officer Waterton was promoted to the rank of Flight Lieutenant, 18 January 1941.
Waterton served as a flight instructor in Canada in throughout 1942.
Air Force Cross
Flight Lieutenant William Arthur Waterton was awarded the Air Force Cross, 1 January 1943.
Waterton was next assigned to the Transatlantic Ferry Command, then transferred to No. 124 Squadron at RAF Manston, where he flew the Supermarine Spitfire Mk.VI and VII. In September 1943, he was assigned to No.1409 (Meteorological) Flight at RAF Oakington, which was equipped with unarmed de Havilland Mosquitos.
In May 1944, Waterton was assigned to the Air Fighting Development Unit (Central Fighter Establishment) at RAF Wittering, testing captured enemy aircraft and comparing them to Allied aircraft.
On 13 April 1945, Flight Lieutenant Waterton was transferred to reserve and called up for Air Force service.
Flight Lieutenant Waterton was promoted to the rank of Squadron Leader in June 1946.
Waterton attended No. 5 Empire Test Pilots School at Hanworth, where he had begun his aviation career in 1939.
After the War, Waterton was selected for the RAF High Speed Flight. Along with Group Captain Edward Mortlock (“Teddy”) Donaldson and Squadron Leader Neville Frederick Duke, he was to attempt a world speed record with the Gloster Meteor F. Mk.IV fighter.

On 7 September 1946, Waterton made made five runs over the course with EE550 during a 21 minute period. However, Group Captain Donaldson, flying Meteor IV EE549, established a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course, averaging 991 kilometers per hour (615.779 miles per hour). [FAI Record File Number 9848] This exceeded the record record set by Group Captain Hugh Joseph Wilson with Meteor IV EE455, 7 November 1945. [FAI Record File Number 9847] (Please see This Day in Aviation for 7 November 1945 at: https://www.thisdayinaviation.com/7-november-1945/ )
Interestingly, Donaldson had said that he thought that Waterton’s Meteor was the faster of the two.

Acting Squadron Leader William Arthur Waterton, R.A.F.O. (Reserve of Air Force Officers), was awarded a Bar to his Air Force Cross (a second award of the AFC), 12 June 1947.
Waterton left the Royal Air Force and joined Gloster Aircraft Co. Ltd. on 21 October 1947as a test pilot at a salary of £1,000 per year. In addition to testing improved Meteor variants, he was also assigned to the experimental E.1/44 and the delta-winged GA.5 Javelin. On 1 April 1948, he was appointed the company’s chief test pilot with an increase to £1,500 per year.
On 6 February 1948, Squadron Leader Waterton, flying a Gloster Meteor F. Mk.IV, VT103, set an Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers, averaging 873.786 kilometers per hour (542.945miles per hour/471.807 knots). The course was from RAF Moreton Valence, southwest of Gloucester, to Evesham Bridge, Pershore Aerodrome, Defford Aerodrome and Grange Court Junction.⁴
Waterton had made an attempt earlier in the day with a Meteor F. Mk.V, averaging only 522 m.p.h. (840 kilometers per hour). Disappointed, he switched to a standard production Meteor IV and tried again.
The second E.1/44 prototype was the first to fly, with Waterton at the controls, 9 March 1948. (The first had been damaged while being transported by truck.) Waterton called the airplane the Gloster Gormless, “since she was so heavy for her single Nene engine.”

On 29 June 1952, while Waterton was conducting the Javelin’s 99th flight, it experienced extreme flutter and both elevators separated from the airplane. Using the horizontal stabilizer’s trim control, Waterton was able to land the aircraft at RAF Boscombe Down, Wiltshire, though at a much higher speed than normal. The landing gear collapsed. The aircraft caught fire and was ultimately destroyed.
Bill Waterton was awarded the George Medal by Queen Elizabeth II.
In July 1953, Bill Waterton married Marjorie E. Stocks at Cheltenham, Gloucestershire.

Very critical of the safety record of the British aircraft industry, Waterton left Gloster and became an aviation correspondent for the Daily Express. After publishing his autobiography, The Quick and the Dead, in 1956, in which he continued his criticism of the aircraft industry, he was fired. The newspaper said that the aviation industry had stopped buying advertising space.
Bill Waterton returned to Canada, residing at Owen Sound, Ontario.
Squadron Leader William Arthur Waterton, AFC and Bar, GM, Royal Air Force, died 17 April 2006, at Owen Sound. He was 90 years of age. His remains were interred at the Oxenden Cemetery, Oxenden, Ontario, Canada.

At Istres, in the south of France, French World War I fighter ace and test pilot Raymond Delmotte flew a Caudron C.460 Rafale single-engine monoplane over a 3-kilometer (1.864 miles) straight course at an average speed of 505.85 kilometers per hour (314.32 miles per hour), setting a new Fédération Aéronautique Internationale (FAI) world record speed for land planes.¹
Flight reported the event:
“. . . The attempt consisted of four trial flights over a regulation three-kilometre straight course, the average time made during all of them being taken as the final result. Delmotte made a preliminary attempt in the morning, but, owing to a crosswind of 10 m.p.h. then prevailing, he was able to attain only 478 km./hr. as the average result. He then waited until the afternoon, when, the wind having fallen to about 2½ m.p.h., he took off again and accomplished an average speed of 505.84 km./hr., according to the official timers, who will submit this figure to the F.A.I. for homologation.”
—FLIGHT The Aircraft Engineer & Airships, No. 1358, Vol. XXVII, Thursday, 3 January 1935 at Page 16
The New York Daily News reported that Delmotte won a prize of 300,000 francs, equivalent to $19,000 U.S. dollars.

The Caudron C.460 Rafale was designed by Marcel Riffard, technical director of Société des Avions Caudron, a French aircraft manufacturer which had been established in 1909. (Rafale means gust: “a brief, strong, rush of wind.”) It was a light-weight, single-seat, single-engine racer with retractable landing gear. Three were built.

The airplane was primarily constructed of spruce, covered with doped fabric, with the engine cowling and fuel tanks fabricated of magnesium. It was 7.125 meters (23 feet, 4½ inches) long with a wingspan of 6.75 meters (22 feet, 1¾ inches) and overall height of 1.8 meters (5 feet, 11 inches). The C.460’s empty weight was 520 kilograms (1,146 pounds) and it had a gross weight of 875 kilograms (1,929 pounds).

The C.460s were originally powered by an air-cooled, supercharged, 7.947-liter-displacement (484.928 cubic inches) Renault 6Q inverted 6-cylinder inline overhead valve (OHV) engine. It had 2 valves per cylinder and a compression ratio of 6:1. The engine produced 310 horsepower at 3,000 r.p.m., and 325 horsepower at 3,200 r.p.m. The direct-drive, left-hand tractor engine turned a two-bladed metal Helices Ratier automatic variable-pitch propeller with a diameter of 1.80 meters (5 feet, 10.9 inches). The Renault 6Q was 1.62 meters (5 feet, 3.8 inches) long, 0.93 meters (3 feet, 0.6 inches) high and 0.52 meters (1 foot, 8.5 inches) wide. It weighed 190 kilograms (419 pounds).
Prior to Delmotte’s speed record attempt, the C.460’s engine was changed to a larger, more powerful 9.501 liter (579.736 cubic inches) Renault 6Q engine, also a direct-drive engine, which produced 370 chaval vapeur (364.9 horsepower) at 3,250 r.p.m. The engine’s centrifugal supercharger turned 26,000 r.p.m. The variable-pitch Ratier propeller was retained.

There is little biographical information available about Raymond Delmotte. He was born at Saint-Quentin, Aisne, France, 11 November 1894. He married Mlle Louisa Dagneaux, and they had three children, Fernande, Raymond, and Ann Marie. He held ten FAI records for speed and distance. He died 13 December 1962.

17 December 1947: At Thermal, California, Jackie Cochran flew her green North American Aviation P-51B Mustang, NX28388, to a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course. Her average speed, after two passes over the course in each direction, was 663.054 kilometers per hour (412.002 miles per hour).
Cochran’s altitude over the record course was at Sea Level.

The airport at Thermal is 115 feet (35 meters) below Sea Level. During December, the daily high temperature averages 71.0 ˚F. (21.7 ˚C.). The airport was established as Thermal Army Airfield during World War II, but today is the Jacqueline Cochran Regional Airport (TRM).
A week earlier, 10 December 1947, Cochran set another record World Record, flying NX28388 over a 100-kilometer (62 miles) closed circuit, averaging 755.668 kilometers per hour (469.549 miles per hour). (FAI Record File Number 4478).
That record still stands.
For a series of six records set in her P-51, Jackie Cochran, who held a commission as a colonel in the United States Air Force, was awarded the Distinguished Flying Cross.

NX28388 was the first of three P-51 Mustangs owned by Jackie Cochran. It was a North American Aviation P-51B-15-NA Mustang built at Inglewood, California in 1944. It was assigned NAA internal number 104-25789 and U.S. Army Air Corps serial number 43-24760. She bought it from North American Aviation, Inc., 6 August 1946. The airplane was registered to Jacqueline Cochran Cosmetics, Inc., 142 Miller Street, Newark, New Jersey, but was based at Jackie’s C-O Ranch at Indio, California. The Mustang was painted “Lucky Strike Green” and carried the number 13 on each side of the fuselage, on the upper surface of the left wing and lower surface of the right wing.
NX28388 was powered by Packard V-1650-7 Merlin V-12, serial number V332415.

Jackie Cochran flew NX28388 in the 1946 Bendix Trophy Race and finished second to Paul Mantz in his P-51C Mustang, Blaze of Noon. Cochran asked Bruce Gimbel to fly the Mustang for her in the 1947 Bendix. There was trouble with the propeller governor and he finished in fourth place. In May 1948, Jackie set two more speed records with NX28388. Jackie and her green Mustang finished in third place in the 1948 Bendix race. She asked another pilot, Lockheed test pilot Sampson Held, to ferry the fighter back to California from Cleveland, Ohio after the race, but,

The P-51B was the first production Mustang to be built with the famous Rolls-Royce Merlin engine, and was virtually identical to the P-51C variant. (The P-51Bs were built by North American Aviation, Inc., at Inglewood, California. P-51Cs were built at North American’s Dallas, Texas plant.) They were 32 feet, 2.97 inches (9.829 meters) long, with a wingspan of 37 feet, 0.31-inch (11.282 meters) and overall height of 13 feet, 8 inches (4.167 meters) high. The fighter had an empty weight of 6,985 pounds (3,168 kilograms) and a maximum gross weight of 11,800 pounds (5,352 kilograms).
P-51Bs and Cs were powered by a liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) Packard V-1650-3 or -7 Merlin single overhead cam (SOHC) 60° V-12 engine which produced 1,380 horsepower at Sea Level, turning 3,000 r.p.m and 60 inches of manifold pressure (V-1650-3) or 1,490 horsepower at Sea Level, turning at 3,000 r.p.m. with 61 inches of manifold pressure (V-1650-7). These were license-built versions of the Rolls-Royce Merlin 63 and 66. The engine drove a four-bladed Hamilton-Standard Hydromatic constant speed propeller with a diameter of 11 feet, 2 inches (3.404 meters).

The P-51B/C had a cruise speed of 362 miles per hour (583 kilometers per hour) and the maximum speed was 439 miles per hour (707 kilometers per hour) at 25,000 feet (7,620 meters). The service ceiling was 41,900 feet (12,771 meters). With internal fuel, the combat range was 755 miles (1,215 kilometers).
In military service, armament consisted of four Browning AN/M2 .50-caliber machine guns, mounted two in each wing, with 350 rounds per gun for the inboard guns and 280 rounds per gun for the outboard.
1,988 P-51B Mustangs were built at North American’s Inglewood, California plant and another 1,750 P-51Cs were produced at Dallas, Texas. This was nearly 23% of the total P-51 production.

17 November 1926: At Hampton Roads, Virginia, Major Mario de Bernardi, Regia Aeronautica, broke his own record, set just four days earlier, when he flew the Aeronautica Macchi M.39, number MM.76, to a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 3 Kilometer Course with an average speed of 416.62 kilometers per hour (258.88 miles per hour).¹
Ing. Mario Castoldi
The Macchi M.39 racing float plane was designed by Mario Castoldi. It was a single-place, single engine monoplane with two pontoons, or floats. The wing is externally braced, has 0° dihedral, and incorporates surface radiators. The M.39 was 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 was 1,300 kilograms (2,866 pounds) and its maximum gross weight was 1,615 kilograms (3,560 pounds).

The M.39 was powered by a water-cooled, normally-aspirated, 31.403 liter (1,916.329 cubic inch) Fiat AS.2 60° DOHC 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.
