23 June 1924: Joseph Sadi-Lecointe set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Distance of 500 Kilometers when he flew a Nieuport-Delâge NiD-42 S sesquiplane to an average speed of 306.70 kilometers per hour (190.57 miles per hour) at Istres, France.¹
Two Nieuport-Delâge NiD-42 S racers were built by Société Nieuport-Astra. The airplane was a single-place, single-engine, strut-braced high-wing sesquiplane (“a plane-and-a-half”) with fixed landing gear. An airfoil was positioned between the wheels.
The NiD-42 S racer was 6.55 meters (21 feet, 5.9 inches) long and 2.20 meters (7 feet, 2.6 inches) high. The upper wingspan was 9.50 meters (31 feet, 2.0 inches) and the lower wing, 2.75 meters (9 feet, 0.3 inches). The vertical gap between the wings was 1.70 meters (5 feet, 6.9 inches). The lower “half wing” had an area of 1.60 square meters (17.22 square feet).
The racer’s empty weight was 1,170 kilograms (2,580 pounds), and gross weight was 1,440 kilograms (3,175 pounds).
The fuselage was a wood monocoque assembly, built in two halves, using as many as six layers of 0.9 mm (0.04 inches) white wood strips, placed diagonally at alternating 90° angles. The completed fuselage was then covered in doped fabric. The upper wing was one built as one piece, using two spruce spars. The surfaces were plywood, covered with fabric. The struts were steel tubing with a streamlined cross section. Cylindrical Lamblin radiators were used for engine cooling, located under the fuselage. The lower “half-wing” was made of duralumin.
The NiD-42 S was powered by a water-cooled, supercharged, 18.473 liter (1,127.265 cubic inch displacement) Société Française Hispano-Suiza Type 42 (also referred to as the 8F series), a single overhead camshaft (SOHC) 90° V-8 engine with a compression ratio of 5.3:1. The standard normally-aspirated engine was rated at 320 horsepower, but Sadi-Lecointe’s was supercharged and required that benzol added to the fuel to prevent pre-ignition. When tested, the engine produced exactly 357.7 horsepower at 1,860 r.p.m. It was a direct-drive engine which turned a two-bladed fixed-pitch propeller.
The NiD-42 S had a maximum speed of 330 kilometers per hour (205 miles per hour) and maximum range of 500 kilometers (311 miles).
Joseph Sadi-Lecointe learned to fly in 1910. The Aero Club de France awarded him its license number 431 on 10 February 1910.
He joined the Service Aéronautique (the original form of the French Air Force) as a mechanic in October 1912, and was designated pilote militaire nº375, 20 September 1913. He served as a pilot during World War I, flying the Blériot XI-2, Morane LA and Nieuprt X, then in December 1915 became a flight instructor at l’Ecole de Pilotage d’Avord.
Sadi-Lacointe was promoted from the enlisted ranks to sous-lieutenant, 17 September 1917, and was assigned as a test pilot at Blériot–Société Pour L’Aviation et ses Dérivés, where he worked on the development of the famous SPAD S.XIII C.1 fighter.
After the War, he was a test pilot for Nieuport-Delâge, and participated in numerous races and set a series of speed and altitude records with the company’s airplanes.
Sadi-Lecointe returned to military service in 1925 and participated in the Second Moroccan War. Then in 1927, he returned to his position as chief test pilot for Nieuport-Delâge. From 1936 to 1940, he served as Inspecteur général de l’aviation civile (Inspector General of Aviation) for the French Air Ministry. With the outbreak of World War II in 1939, Lieutenant Colonel Sadi-Lecointe was again recalled to military service as Inspector of Flying Schools.
With the Fall of France, Sadi-Lacointe joined La Résistance française and operated with the group Rafale Andromède. He was captured and tortured by the Gestapo at Paris, and died as a result, 15 July 1944.
Joseph Sadi-Lecointe, Commandeur Ordre national de la Légion d’honneur, was awarded the Croix de Guerre in three wars. He was posthumously awarded the Médaille de la Résistance. The Aéro-Club de France awarded him its Grande Médaille d’Or de l’Aéro-Club de France. During his flying career, Sadi-Lecointe set seven World Records for Speed, and three World Records for Altitude.
22 June 1962: At Istres, France, Société des Avions Marcel Dassault test pilot Jacqueline Marie-Thérèse Suzanne Douet Auriol flew a delta-winged Dassault Mirage III C interceptor to set a new Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 100 Kilometers. Her average speed over the course was 1,850.2 kilometers per hour (1,149.7 miles per hour).¹ Mme. Auriol broke the record set 6 October 1961 by Jacqueline Cochran with a Northrop T-38A Talon.²
The Dassault Mirage III C was the first production variant of the Mirage series. It was a single-place, single-engine tailless-delta-wing interceptor designed for Armée de l’air (the French air force), with variants for export. It was designed as a light-weight fighter capable of Mach 2 speeds.
The Mirage III C was 45 feet, 5 inches (13,843 meters) long with a wingspan of 27 feet, 0 inches (8.230 meters) and height of 14 feet, 9 inches (4.496 meters.) The fuselage had a horizontal ellipse cross section and incorporated the Area Rule, similar to the delta wing Convair F-102A. The Mirage IIIC had an empty weight of 12,350 pounds (5,602 kilograms) and maximum takeoff weight of max gross 22,860 pounds (10,369 kilograms).
The interceptor’s low-mounted delta wings used trailing edge flight controls, with ailerons outboard, elevators at the center and small trim tabs inboard. The leading edges were swept aft to 60° 34′ and there was 2° 30′ anhedral. The total wing area was 366 square feet (34.00 square meters).
The Mirage III C was powered by a Société nationale d’études et de construction de moteurs d’aviation (SNECMA) Atar 09C single shaft, axial-flow turbo-réacteur (turbojet engine) with afterburner. The engine used a 9-stage compressor section and 2-stage turbine. It was rated at 9,430 pounds of thrust (41.947 kilonewtons), and 13,669 pounds (60.803 kilonewtons) with afterburner. The Atar 09C was 5.900 meters (19 feet, 4.28 inches) long, 1.000 meters (3 feet, 3.37 inches) in diameter and weighed 1,456 kilograms (3,210 pounds).
When configured as a high-altitude interceptor, the Mirage could be equipped with a hypergolic liquid fueled Société d’Études pour la Propulsion par Réaction SEPR 841 rocket engine mounted under the rear fuselage. When the booster pack not used, a small additional fuel tank would be mounted in the same position.
The Dassault Mirage III C could climb to 30,000 feet (9,144 meters) in 3 minutes, 60,000 feet (18,288 meters) in 6 minutes, 10 seconds, and reach 72,000 feet (21,946 meters) in 9 minutes. It had an economical cruise speed of 0.9 Mach at 40,000 feet (12,192 meters), and maximum speed of Mach 2.3 at 36,000 feet (10,973 meters). The maximum range with external fuel tanks was 1,850 miles (2977 kilometers).
The interceptor was equipped with search radar and a missile targeting computer. Armament consisted of a modular gun pack with two Direction des Études et Fabrications d’Armement (DEFA) 5-52 autocannon with 125 rounds of ammunition per gun (the targeting computer had to be removed for this installation). A Nord AA.20 guided air-to-air missile could be carried under the fuselage on a centerline hardpoint, or a AS.30 air-to-ground missile. Both of these were controlled by the pilot through a cockpit joystick. Alternatively, two Sidewinder infrared-homing air to air missiles were carried on underwing pylons.
95 Mirage III Cs were built. The served with the Armée de l’air from 1961 to 1988.

14 June 1963: Jacqueline Marie-Thérèse Suzanne Douet Auriol flew an Avions Marcel Dassault Mirage III R (nº 307) over a 100 kilometer course near Istres, France, at an average of 2,038.70 kilometers per hour (1,266.79 miles per hour), setting a Fédération Aéronautique Internationale (FAI) world speed record.¹
Mme. Auriol broke the record set six weeks earlier by Jackie Cochran in a Lockheed TF-104G Starfighter. ²
The Mirage III R is a single seat, single-engine, supersonic all-weather reconnaissance variant of the Mirage IIIE delta-winged fighter. The nose is modified to carry five cameras. Radar and weapons were deleted.
The Avions Marcel Dassault Mirage IIIE was 15,04 meters (49 feet, 4⅛ inches) long with a wingspan of 8,22 meters (26 feet, 11⅔ inches) and height of 4,45 meters (14 feet, 7⅕ inches). The interceptor’s empty weight was 7,050 kilograms (15,543 pounds), and maximum takeoff weight was 13,700 kilograms (30,203 pounds).
The aircraft flown by Jacqueline Auriol was powered by a Société nationale d’études et de construction de moteurs d’aviation (SNECMA) Atar 09C single shaft, axial-flow turbo-réacteur (turbojet engine) with afterburner. The engine used a 9-stage compressor section and 2-stage turbine. It was rated at 9,430 pounds of thrust (41.947 kilonewtons), and 13,669 pounds (60.803 kilonewtons) with afterburner. The Atar 09C was 5.900 meters (19 feet, 4.28 inches) long, 1.000 meters (3 feet, 3.37 inches) in diameter and weighed 1,456 kilograms (3,210 pounds).
The Dassault Mirage IIIE had a maximum speed of 2,350 kilometers per hour (1,460 miles per hour). Its service ceiling was 17,000 meters (55,774 feet), and its combat range was range 1,200 kilometers (746 miles).
23 February 1951: At Istres, France, Société des Avions Marcel Dassault chief test pilot Konstantin Wladimir (“Kostia”) Rozanoff made the first flight of the Mystère MD.452 prototype, F-WFUU, c/n 01. This was a development of the Dassault Ouragan MD.450 with the wings’ leading edge swept from 14° to 30°. It was powered by a Rolls-Royce Nene turbojet engine. Rozanoff believed, though it was not confirmed, that he had broken the Sound Barrier.
A series of prototypes were built before the fighter bomber was put into production as the Mystère IIC. 171 were built between 1954 and 1957.
The Mystère IIC was a single seat, single engine turbojet-powered fighter bomber produced for the Armée de l’Air. It was 38 feet 6 inches (11.735 meters) long with a wingspan of 42 feet, 9 inches (13.030 meters) and overall height of 14 feet (4.267 meters). The fighter had an empty weight of 11,495 pounds (5,214 kilograms) and maximum takeoff weight of 16,480 pounds (7,475 kilograms). The powerplant was a SNECMA ATAR 101D-1 turbojet which produced 6,610 pounds of thrust (29.403 kilonewtons).
The maximum speed of the Mystère IIC was 660 miles per hour (1,062 kilometers per hour). Its range was 550 miles (885 kilometers) and the service ceiling was 50,000 feet (15,240 meters).
The MD.452 was armed with two Direction des Études et Fabrications d’Armement (DEFA) 30mm revolver cannon with 150 rounds of ammunition per gun, and up to 2,000 pounds (907 kilograms) of bombs.
The prototype Dassault Mystère, F-WFUU, crashed at Istres 3 March 1953 when a wing tip fuel tank broke away and struck the airplane’s tail, killing test pilot Charles Monier.
Kostia Romanoff was killed 3 April 1954 while demonstrating a Mystère IVB.
