20–22 June 1972: Westland AH.1 Lynx, c/n 02/11, XX153, flown by then Westland Chief Pilot Leonard Roy Moxham and flight test engineer Michael Ball, set two Fédération Aéronautique Internationale (FAI) World Records for Speed. Flying over a straight 15/25 kilometer course on 20 June, the Lynx averaged 321.74 kilometers per hour (199.92 miles per hour).¹ Two days later, the Lynx flew a closed 100 kilometer circuit at an average speed of 318.50 kilometers per hour (197.91 miles per hour).² Both of these records were for helicopters in the 3,000–4,500 kilogram weight class.
XX153 is at the Museum of Army Flying, Middle Wallop, Hampshire, England.
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).
1 June 1964: At Edwards Air Force Base, Jackie Cochran flew a Lockheed F-104G Starfighter, serial number 62-12222, over a 100 kilometer (62.137 miles) closed circuit without payload, averaging 2,097.27 kilometers per hour (1,303.18 miles per hour).¹ This new Fédération Aéronautique Internationale (FAI) speed record broke the one set a year earlier—2,038.70 kilometers per hour (1,266.79 miles per hour)—by Cochran’s friend and competitor, Jacqueline Auriol, who flew a Dassault Mirage IIIR delta-winged reconnaissance fighter at Istres, France. ²
Designed by the legendary Kelly Johnson as a Mach 2 interceptor, the Starfighter was used as a fighter bomber by Germany. The F-104G was most-produced version of the Lockheed Starfighter. It had a strengthened fuselage and wings, with hardpoints for carrying bombs, missiles and additional fuel tanks. Built by Lockheed, they were also licensed for production by Canadair, Dornier, Fiat, Fokker, Messerschmitt and SABCA.
The F-104G is a single-seat, single-engine fighter bomber, 54 feet 8 inches (16.662 meters) long with a wingspan of just 21 feet, 9 inches (6.629 meters) and overall height of 13 feet, 6 inches (4.115 meters). The empty weight is 14,000 pounds (6,350.3 kilograms) and loaded weight is 20,640 pounds (9,362.2 kilograms).
The F-104G was powered by a General Electric J79-GE-11A engine, a single-spool, axial-flow, afterburning turbojet, which used a 17-stage compressor section and 3-stage turbine. The J79-GE-11A is rated at 10,000 pounds of thrust (44.48 kilonewtons), and 15,800 pounds (70.28 kilonewtons) with afterburner. The engine is 17 feet, 4.0 inches (5.283 meters) long, 3 feet, 2.3 inches (0.973 meters) in diameter, and weighed 3,560 pounds (1,615 kilograms).
The maximum speed is 1,328 miles per hour (2,137.2 kilometers per hour). It has a combat radius of 420 miles (675.9 kilometers) or a ferry range of 1,630 miles (2,623.2 kilometers). The service ceiling is 50,000 feet (15,240 meters).
The Starfighter’s standard armament consists of a 20 mm General Electric M61A1 Vulcan 6-barreled Gatling gun, with 725 rounds of ammunition, and up to four AIM-9 Sidewinder air-to-air heat seeking missiles could be carried on the wingtips or under wing pylons. In place of missiles two wingtip fuel tanks and another two underwing tanks could be carried.
On NATO alert, the F-104G was armed with a B43 variable-yield nuclear bomb on the fuselage centerline hardpoint. The B43 could be set for explosive force between 170 kilotons and 1 megaton and was designed for high-speed, low-altitude, laydown delivery.
Jackie Cochran set three speed records with this F-104 in May and June 1964.³ Under the Military Assistance Program, the U.S. Air Force transferred it to the Republic of China Air Force, where it was assigned number 4322. It crashed 17 July 1981. The pilot, Yan Shau-kuen, ejected.
21 May 1949: Captain Hubert Dale Gaddis, Field Artillery, United States Army, flew a prototype Sikorsky S-52-1 helicopter, serial number 52003, registration NX92824, to a Fédération Aéronautique Internationale (FAI) World Record for Altitude Without Payload of 6,468 meters (21,220 feet) over Bridgeport, Connecticut. ¹ The flight was observed by National Aeronautic Association representatives Walter Goddard and Charles Logsdon.
The Sikorsky S-52-1 was a completely new design based on the company’s experience with the earlier R-4 and R-5/S-51 models. It was a two-place light helicopter of all metal monocoque construction, using primarily aluminum and magnesium. With Sikorsky test pilot Harold Eugene (“Tommy”) Thompson at the controls, the prototype made its first flight 4 May 1948.
The three-bladed fully-articulated articulated main and two-bladed tail rotor were also of all metal construction. The main rotor had a diameter of 33 feet (10.058 meters) and rotated counter-clockwise as seen from above. (The advancing blade is on the right side of the helicopter.) It had an extruded aluminum spar, covered with sheet duralumin, riveted and glued in place. The blade used a NACA 0012 airfoil with -6° twist. The two-bladed semi-rigid tail rotor was mounted on the left side of the tail boom in a pusher configuration. It had a diameter of 6 feet, 4 inches (1.930 meters) and rotated counter clockwise, as seen from the helicopter’s left. (The advancing blade is at the top of the tail rotor arc.)
The S-52-1 was powered by an air-cooled, normally-aspirated, 425.29-cubic-inch-displacement (6.97 liter) Franklin Engine Company 6V6-245-B16F (O-425-1) vertically-opposed 6-cylinder overhead valve engine. The engine was rated at 245 horsepower at 3,275 r.p.m.
On 27 April 1949 Tommy Thompson flew the same helicopter to an FAI speed record of 208.49 kilometers per hour (129.55 miles per hour) over a 3 kilometer straight course at Cleveland, Ohio, ² and on 6 May, to 197.54 kilometers per hour (122.75 miles per hour) over a 100-kilometer course between Milford and Westbrook, Connecticut. ³
Hubert Dale Gaddis was born in Jasper County, Missouri, 9 September 1920, the first of two children of Hubert E. Gaddis, a utility company purchasing agent, and Beatrice Mae Cook Gaddis.
The family trelocated to Tulsa, Oklahoma, where Hubert attended Central High School. While there, he developed an interest in radio. Gaddis graduated in 1938.
Gaddis married Martha Tucker in 1950. They would have three children,Cheryl, Sandra and Dale.
Gaddis enlisted in the United States Army in Oklahoma, 24 September 1942. He had brown hair and hazel eyes, was 5 feet, 6 inches (1.68 meters) tall and weighed 133 pounds (60.3 kilograms).
Gaddis was commissioned a second lieutenant, Army of the United States (AUS), 18 February 1944. He remained in the Army following World War II as an officer in the Field Artillery (Regular Army). In 1956, he graduated of the Army Command and General Staff College.
On September 8 1966, Gaddis was promoted to the rank of colonel (temporary). The rank became permanent 1 July 1971. He was released from military service 28 February 1974. During his career, Colonel Gaddis had been awarded the Distinguished Flying Cross, the Bronze Star Medal, and the Air Medal with 14 oak leaf clusters (15 awards).
Colonel Hubert Dale Gaddis, United States Army (Retired) died 24 February 1976 at the age of 55 years. He was buried at Woodlawn Memorial Gardens, Ozark, Alabama.
