11 June 1971: Sheila Scott O.B.E. (née Sheila Christine Hopkins) departed Nairobi, Kenya, on her third solo around-the-world flight. On this flight she used a new airplane, a twin-engine Piper PA-23-250 Aztec D which she named Mythre. It carried United Kingdom registration G-AYTO. Scott used a NASA navigation and locator communication system to constantly relay her position to a Nimbus weather satellite, and from there to a ground station.

Sheila Scott planned to not only fly around the world, but to fly from the Equator, over the North Pole, and back to the Equator again. She flew her Aztec from London, England, to Nairobi, Kenya, where she began the Equator–North Pole–Equator portion of the flight.

Scott took off from Nairobi on 11 June 1971 and headed northward to Khartoum, Sudan; Bengazi, Libya; Malta; arriving back at London on 21 June. From there she continued to Bodø, Norway; Andøya, Norway; Station Nord, Greenland; across the North Pole on 28 June; then southward to Barrow, Alaska; arriving at Anchorage, Alaska, on 3 July; San Francisco, California, to Honolulu, Hawaii, on 11 July. She recrossed the Equator heading south to Canton Island. On 23 July, Mythre arrived at Nadi, Viti Levu, Fiji, and then flew on to Noumea, New Caledonia. After a stop at Townsville, Queensland, Scott arrived at Darwin, Northern Teritory, Australia, 1 August. From there she continued to Singapore; Madras, India; Karachi, Pakistan; Bahrain; Athens, Greece; and finally completed her journey at London on 4 August. The trip took 55 days.

During the circumnavigation, Sheila Scott set seven Fédération Aéronautique Internationale (FAI) World Records for Speed Over a Recognized Course: Andøya, Norway, to Station Nord, Greenland, 213.61 kilometers per hour (132.73 miles per hour) ¹; Nord to Barrow, Alaska, 183.73 km/h (114.16 mph) ²; San Francisco, California, to Honolulu, Hawaii, 236.56 km/h (146.99 mph) ³; Darwin, Northern Territory, Australia, to London, England, 160.19 km/h (99.54mph). ⁴ Three of these records remain current. ⁵

Ms. Scott’s airplane was a 1971 Piper 23-250 Aztec (“Aztec D”), serial number 27-4568. The airplane was assigned the United Kingdom registration G-AYTO on 3 March 1971. The Aztec D was a six-place twin-engine light airplane based on the earlier PA-23-235 Apache, with a larger cabin and more powerful engines. It was of all-metal construction and had retractable tricycle landing gear. The Aztec D is 31 feet, 2.625 inches (9.516 meters) long with a wingspan of 37 feet, 1.750 inches (11.322 meters) and overall height of 10 feet, 3.875 inches (3.146 meters). The wing has 5° dihedral. The Aztec D has an empty weight of 3,042 pounds (1,380 kilograms) and a gross weight of 5,200 pounds (2,359 kilograms).

The Aztec D is powered by two air-cooled, fuel-injected, 541.511-cubic-inch-displacement (8.874 liter) AVCO Lycoming IO-540-C4B5 6-cylinder, horizontally-opposed, direct-drive engines. The -C4B5 has a compression ratio of 8.5:1 and a Maximum Continuous Power/Takeoff rating of 250 horsepower at 2,575 r.p.m. It weighs 374 pounds (170 kilograms). The engines drive two-bladed Hartzell constant-speed propellers with a diameter of 6 feet, 2 inches (1.880 meters).

The PA-23-250 Aztec D has a maximum structural cruising speed (VNO) of 172 knots (198 miles per hour/319 kilometers per hour) at 7,500 feet (2,286 meters) and maximum speed (VNE) of 216 knots 249 miles per hour (400 kilometers per hour). The service ceiling is 19,800 feet (6,035 meters). With standard fuel capacity of 144 gallons (545 liters) the airplane’s range is 1,055 miles (1,698 kilometers). Mythre carried an auxiliary fuel tank in the passenger cabin.

After the around-the-world flight, Scott returned Mythre to the Piper Aircraft Company at Lock Haven, Pennsylvania, for overhaul. Following Tropical Storm Agnes in June 1972, the Piper factory was flooded to a depth of 16 feet (4.9 meters) and Scott’s airplane, along with many others and much of the tooling for aircraft manufacture, was destroyed.

7 June 1919

“Portrait of famous French aviatrix Baroness de la Roche on July 1, 1919, taken after she broke the world’s record for altitude reached by a woman. (Photo: Bettmann/Corbis)” —YAHOO!

7 June 1919: Numerous sources report that the Baroness de la Roche (née Élisa Léontine Deroche) set a “world record” for women with a Caudron G.3 biplane, sometime during June 1919.

There is considerable variation among these sources, though, with dates variously given as 7 June, 12 June, 17 June, or most often, simply June. And the altitude which she is credited is also confused, varying from 3,900 meters, 4,260 meters, 4,500 meters, 4,785 meters, 4,800 meters, and even 5,150 meters.

The actual facts are uncertain. Mme. Deroche’s flight was not certified by the Fédération Aéronautique Internationale (FAI).

A contemporary source of aviation news reported:

A Women’s Height Record

     Flying a small Caudron G.3 biplane, Baroness de la Roche, during a flight which lasted  1 hr. 49 mins., went up to an altitude of 3,900 metres (12,870 ft.), which is claimed, in Paris, as a woman’s record.

     Miss Ruth Law has cabled from New York claiming that in September 1917, she went up to 4,240 metres.

FLIGHT & The AIRCRAFT ENGINEER, No. 546, Vol. XI, No. 24, 12 June 1919, Page 780, Column 2

Women’s Height Record

     In view of the fact that Miss Ruth Law had claimed to have bettered the performance of Baroness de la Roche the other day, when she flew to a height of 3,900 metres (12,870 ft.), a new attempt was made on June 12. Starting from Issy on a Caudron biplane, Baroness de la Roche climbed steadily until she reached a height of 4,800 metres (15,840 ft.) Coming down she lost her way in a mist, but eventually landed safely at Gastins, 8 kiloms. from Nangis, after a flight of 2 hrs. 7 mins.

Pushing up World’s Height Record

     Not satisfied with his height record of last week Lieut. Casole [sic] on June 14 took his Nieuport up to 10,100 metres (33,330 feet) during a flight from Villacoublay which lasted 1 hr. 55 mins. As in his previous flights, he used a Nieuport, fitted with a 300 h.p. Hispano-Suiza motor. His previous highest was 9,500 metres (31,350 ft.) and not 51,350 ft., as a printer’s error made it appear in our last issue.

FLIGHT & The AIRCRAFT ENGINEER, No. 547, Vol. XI, No. 25, 12 June 1919, Page 799, Columns 1

While Jean Casale’s ¹ record of 9,520 meters (31,234 feet), set 14 June 1919, ² is recognized by the Fédération Aéronautique Internationale, the FAI did not recognize records set by women until 28 June 1929. Neither Mme. Deroche or Miss Law have any records listed in the FAI’s online data base.

Société des Avions Caudron G.3. (Musée de l’Air et de l’Espace)

The Caudron G.3 is the same type airplane flown by Adrienne Bolland when she crossed the Andes Mountains of South America nearly two years later.

The Caudron G.3 was a World War I reconnaissance airplane and flight trainer manufactured by Société des Avions Caudron. It is called a sesquiplane because the lower wing is significantly shorter than the upper. The G.3 was a single-engine aircraft that was built in single- and two-place variants. The engine and cockpit are contained in a very short fuselage, supporting the wings and landing gear. Tail control surfaces are mounted on an open framework tail boom.

Caudron G.3 sesquiplane. (Musée de l’Air et de l’Espace)

The Caudron G.3 was 6.90 meters (22 feet, 7 inches) long with an upper wingspan of 13.26 meters (43 feet, 6 inches). The height of the aircraft was 2.60 meters (8 feet, 5 inches). The airplane had an empty weight of 420 kilograms (926 pounds) and maximum weight of 736 kilograms (1,623 pounds).

The G.3 was powered by an air-cooled, normally-aspirated 10.910 liter (665.791 cubic inches) Société des Moteurs Le Rhône 9C nine cylinder rotary engine with a compression ratio of 5:1. It was rated at 70 cheval vapeur (1 ch = 0.99 horsepower) at 1,100 r.p.m., and 80 cheval vapeur  at 1,200 r.p.m., but able to produce a maximum 92 cheval vapeur (90.77 horsepower) at 1,300 r.p.m. It drove a two-bladed, fixed-pitch wooden propeller. The 9C was 0.810 meters (2 feet, 7.9 inches) long, 0.930 meters (3 feet, 6.1 inches) in diameter and weighed 119 kilograms (262 pounds).

The Caudron G.3 had a maximum speed of 110 kilometers per hour (68 miles per hour) and service ceiling of 5,000 meters (16,404 feet). Its range was 330 kilometers (205 miles).

By the end of World War I, Caudron had built 2,402 G.3s.

Élisa Léontine Deroche

Élisa Léontine Deroche was born 22 August 1882 at nº 61, Rue de la Verrerie, in the 4e arrondissement, Paris, France. She was the daughter of Charles François Deroche, a plumber, and Christine Calydon Gaillard Deroche. In her early life she had hoped to be a singer, dancer and actress. Mlle. Deroche used the stage name, “Raymonde de Laroche.”

Mlle. Deroche married M. Louis Léopold Thadome in Paris, 4 August 1900. They divorced 28 June 1909.

She had a romantic relationship with sculptor Ferdinand Léon Delagrange, who was also one of the earliest aviators, and it was he who inspired her to become a pilot herself. They had a son, André, born in 1909. Delagrange was killed in an airplane accident in 1910. They never married.

After four months of training under M. Chateu, an instructor for Voison, at Chalons, she made her first solo flight on Friday, 22 October 1909. On 8 March 1910, Élisa Léontine Deroche was the first woman to become a licensed pilot when she was issued Pilot License #36 by the Aéro-Club de France.

Pilot Certificate number 36 of the Aéro-Club de France was issued to Mme de Laroche. (Musée de l’Air et de l’Espace)

In a 30 October 1909 article about her solo flight, Flight & The Aircraft Engineer referred to Mme. Deroche as “Baroness de la Roche.” This erroneous title of nobility stayed with her in the public consciousness. Deroche participated in various air meets, and on 25 November 1913, made a non-stop, long-distance flight of four hours duration, for which she was awarded the Coupe Femina by the French magazine, Femina.

On 20 February 1915, Mme. Deroche married Jacques Vial at Meudon, Hauts de Seine, Île-de-France, France.

During World War I she was not allowed to fly so she served as a military driver.

Mme. Deroche was at Le Crotoy in northern France, co-piloting an experimental airplane, a civil variant of the Caudron G.3. The aircraft suddenly  pitched down and crashed, killing Deroche and the pilot, M. Barrault. Mme. Deroche was 36 years old. Élisa Léontine Deroche was buried at the Cimetière du Père-Lachaise, Paris, France.

FLIGHT and Aircraft Engineer briefly mentioned the flight:

“. . . On the same day S.N.C.A.S.E. claimed the world’s helicopter height record when the Alouette II, powered by a Turboméca Artouste, reached 27,100ft. The machine took off from Buc, near Paris, climbed for 42 min and landed at Montesson. The pilot was M. Jean Boulet.”

FLIGHT and AIRCRAFT ENGINEER, No. 2420 Vol. 67. Friday, 10 June 1955, at Page 784

Powered by a Turboméca Artouste IIB1 turboshaft engine, the Alouette II was the first gas turbine helicopter to enter series production. SNCASE would become Aérospatiale, later, Eurocopter, and is now Airbus Helicopters.

The Alouette II is a 5-place light helicopter operated by a single pilot. The fuselage is 9.66 meters (31 feet, 9 inches) long. The three-bladed fully-articulated main rotor has a diameter of 10.20 meters (33 feet, 6 inches). It turns clockwise, as seen from above. (The advancing blade is on the left side of the helicopter.) Normal main rotor speed, NR, is 350–360 r.p.m. The two-blade anti-torque rotor is 1.81 meters (9 feet, 11.25 inches) in diameter and turns clockwise, as seen from the helicopter’s left side. (The advancing blade is below the helicopter.) It turns at 2,020 r.p.m.

The SE.3130 has an empty weight of 895 kilograms (1,973 pounds) and a maximum takeoff weight (MTOW) of 1,600 kilograms (3,527 pounds). The prototype was powered by one Turboméca Artouste IIB1 turboshaft engine which produced 400 horsepower, but was derated to 360 horsepower for installation in the Alouette II.

The helicopter has a cruise speed 175 kilometers per hour (109 miles per hour) at Sea Level, and a maximum speed of 185 kilometers per hour (115 miles per hour) at Sea Level. VNE is 195 kilometers per hour (121 miles per hour.)

The service ceiling is 4,000 meters (13,123 feet) at 1,500 kilograms (3,307 pounds) gross weight. The absolute ceiling is 4,500 meters (14,764 feet). At 1,350 kilograms (2,976 pounds) the Alouette II has a hover ceiling in ground effect, HIGE, of 3,400 meters (11,155 feet) and hover ceiling out of ground effect of 1,900 meters (6,234 feet). At 1,500 kilograms the Alouette II’s HIGE is 2,000 meters (6,560 feet) and HOGE is 600 meters (1,968 feet).

The SE.3130 Alouette was in production from 1956 until 1975. More than 1,300 of these helicopters were built.

Jean Boulet was born 16 November 1920, in Brunoy, southeast of Paris, France. He graduated from Ecole Polytechnique in 1940 and the Ecole Nationale Supérieure de l’aéronautique In 1942. As an officer of the Armée de l’Air (French Air Force) he was sent to the United States for training as a fighter pilot, and later as a helicopter pilot. In 1947 he  joined Société nationale des constructions aéronautiques du Sud-Est (SNCASE) as an engineer and test pilot. As a test pilot he made the first flight in every helicopter produced by SNCASE, which would become Sud-Aviation and later Aérospatiale (then, Eurocopter, and now, Airbus Helicopters). He set 24 Fédération Aéronautique Internationale world records for speed, distance and altitude. While flying a SE 530 Mistral fighter, 23 January 1953, he entered an unrecoverable spin and became the first French pilot to escape from an aircraft by ejection seat during an actual emergency. Médaille de l’Aéronautique. In 1972 he was appointed Officier de la Légion d’honneur. He had more than 9,000 flight hours with over 8,000 hours in helicopters.

Jean Boulet died at Aix-en-Provence, 15 February 2011, at the age of 90.

Jackie Cochran set a third FAI speed record with a Lockheed F-104G Starfighter, 3 June 1964. (FAI)

3 June 1964: At Edwards Air Force Base in the high desert of southern California, Jackie Cochran set a third Fédération Aéronautique Internationale (FAI) speed record with the Lockheed F-104G Starfighter, 62-12222. She flew over a 500 kilometer (310.686 miles) closed course, without payload, averaging 1,814.37 kilometers per hour (1,127.397 miles per hour). ¹ She broke her own record, set over the same course in 1953 with an Orenda-powered Canadair Sabre Mk.3. 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.

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.
