29 June 1900: Famed French aviator, poet and author, Antoine Marie Jean-Baptiste Roger, comte de Saint Exupéry, was born at No. 8 rue Payrat,¹ Lyon, Departement du Rhône, Rhône-Alpes, France. He was the third of five children of Jean Marc Martin comte de Saint-Exupéry and Andrée Louise Marie de Boyer de Fonscolombe de la Mole, comtesse de Saint-Exupéry. As the oldest son, Antoine inherited his father’s title of nobility.
While serving in the French cavalry, Saint-Exupéry took private flying lessons. He made his first solo flight 9 July 1921, and soon earned a civil pilot’s certificate. Now eligible for military flight training, he was transferred to the Aéronautique Militaire in Morocco, where he was awarded his military aviator’s certificate, No. 19398, 23 December 1921.
Saint-Exupéry was promoted to caporal 5 February 1922. He underwent further training as an officer cadet and received a commission as a sous-lieutenant 10 October 1922.
On 1 May 1923, Sous-lieutenant Saint-Exupéry crashed a Hanriot HD-14 trainer on takeoff. A passenger was severely injured. Saint-Exupery was grounded. The accident was caused by pilot error, and he released from military service, 5 June 1923.
Saint-Exupéry was engaged to marry Mlle. Louise de Vilmorin. Because of the crash, he promised that he would give up aviation and found employment as an office worker. The engagement ended and he went back to flying.
In 1926, he joined la Compagnie Générale d’Entreprise Aéronautique (C.G.E.A.), which in 1927 would become Compagnie générale aéropostale, (C.G.A.)— Aéropostale,—the predecessor of Air France, in North Africa and South America.
“Transport of the mails, transport of the human voice, transport of the flickering pictures—in this century as in others our highest accomplishments still have the single aim of bring men together.” —Antoine de Saint-Exupéry, 1939
Comte de Saint-Exupéry married Sra. Consuelo Suncin-Sandoval Zeceña, 22 April 1932, at Nice, Alpes-Maritimes, Provence-Alpes-Côte d’Azur, France.
During this time, Saint-Exupéry also began his career as an author. His first book, Courrier Sud, was published in 1929. Vol de Nuit (English edition: Night Flight), was published in 1931. His autobiographical Wind, Sand and Stars, published in 1939, is very highly recommended.
When his friend, Henri Guillaumet, went down in the Cordillera de los Andes, about 123 miles (198 kilometers) west of Mendoza, Argentina, and then walked out over the next five days, Saint-Exupéry wrote:
“What saves a man is to take a step. Then another step. It is always the same step, but you have to take it.”
— Antoine de Saint-Exupéry, Terre des hommes (English edition: Wind, Sand and Stars), translated from the French by Lewis Galantière, Harcourt Brace & Company, New York, Chapter II at Page 37
On 7 April 1930, Saint-Exupéry was appointed Chevalier de la Légion d’honneur.
On 29 December 1935, while flying his red and white Caudron C.630 Simoun, F-ANRY, in a race from Paris, France, to Sài Gòn, French Indo-China, Saint-Exupéry crashed in the Sahara desert. He and his mechanic, André Prévost, were marooned without food or water. They wandered aimlessly for four days and were near death when they were rescued by a Bedouin tribesman. Saint-Exupéry wrote about the experience in Wind, Sand and Stars, and it was the inspiration for his classic novel, The Little Prince.
Saint-Exupéry traveled to Spain in 1937 to observe the Spanish Revolution. He was horrified by what he experienced. “War is not an adventure,” he wrote. “It is a disease.”
Antoine de Saint-Exupéry was promoted to Officier de la Légion d’honneur in 1939.
Following the outbreak of World War II, Saint-Exupéry returned to service with the Armée del’Air, flying in a reconnaissance squadron. With the surrender of France to the German invaders, he fled to Portugal. Saint-Exupéry sailed from Lisbon 20 December 1940 aboard S.S. Siboney, arriving at the Port of New York, 31 December.
In April 1943, he returned to the war flying with the Free French Air Force, the Forces Aériennes Françaises Libres.
He flew a twin-engine Lockheed F-5B, an unarmed photographic reconnaissance variant of the P-38J Lightning fighter. His squadron, 31e escadre,Groupe 2/33, operated from Borgo, an airfield on the northeast coast of Corsica.
Commandant Saint-Exupéry disappeared with his Lockheed F-5B-1-LO Lightning photo reconnaissance airplane (serial number 42-68223) while on a mission to Grenoble and Annecy, at the base of the French Alps, 31 July 1944.
His identity bracelet was found in 1998 by a fisherman, off the southern coastline of France. Wreckage of the F-5B was located on the sea floor in May 2000.
21 June 1972: Aérospatiale Chief Test Pilot Jean Boulet set a Fédération Aéronautique Internationale (FAI) Absolute World Record for helicopters by flying the first Aérospatiale SA 315 Lama, serial number 315-001, to an altitude of 12,442 meters (40,820 feet) from Aérodrome d’Istres, northwest of Marseille, France.¹ He also set two class and sub-class world records.² These records remain current.
The SA 315B Lama was designed to perform at the very high altitudes and temperatures necessary for service with the Indian Army. It combined an SE.3130 Alouette II airframe with a much more powerful Turboméca Astazou IIIB turboshaft engine—derated to 550 shaft horsepower—and the rotor system, transmission and gearboxes from the larger 7-place Alouette III.
The record-setting helicopter was modified by removing all equipment that was not needed for the record flight attempt. Various instruments and the co-pilot and passengers seats were taken out of the cockpit, as well as the helicopter’s synchronized horizontal stabilizer and tail rotor guard. The standard fuel tank was replaced with a very small tank holding just 70 kilograms (approximately 22.7 gallons) of jet fuel. Turboméca modified the engine to increase the output shaft r.p.m. by 6%. After Jean Boulet started the turbine engine, mechanics removed the battery and starter motor to decrease the weight even further.
In just 12 minutes, the Lama had climbed to 11,000 meters (36,089 feet). As he approached the peak altitude, the forward indicated airspeed had to be reduced to 30 knots (34.5 miles per hour, 55.6 kilometers per hour) to prevent the advancing main rotor blade tip from reaching its Critical Mach Number in the thin air, which would have resulted in the blade stalling. At the same time, the helicopter was approaching Retreating Blade Stall.
When the helicopter could climb no higher, Boulet reduced power and decreased collective pitch. The Turboméca engine, not calibrated for the very high altitude and cold temperature, -62 °C. (-80 °F.), flamed out. With no battery and starter, a re-start was impossible. Boulet put the Lama into autorotation for his nearly eight mile descent. Entering multiple cloud layers, the Plexiglas bubble iced over. Because of the ice and clouds, the test pilot had no outside visibility. Attitude instruments had been removed to lighten the helicopter. Boulet looked up through the canopy at the light spot in the clouds created by the sun, and used that for his only visual reference until he broke out of the clouds.
Still in autorotation, the SA 315 missed touching down exactly on its takeoff point, but was close enough that FAI requirements were met.
Two days earlier, 19 June 1972, Boulet and fellow test pilot Gérard Boutin had set another FAI World Record for Altitude Without Payload, when they flew the Lama to 10,856 meters (35,617 feet).³ This record also still stands.
The SA 315B Lama is a 5-place light turboshaft-powered helicopter which is operated by a single pilot. The helicopter was built to meet the specific needs of the Indian Air Force for operations in the Himalayan Mountains. It was required to take off an land at an altitude of 6,000 meters (19,685 feet) while carrying a pilot, one passenger and 200 kilograms (441 pounds) of cargo.
The fuselage is 10.26 meters (33 feet, 7.9 inches) long. With all rotors turning, the helicopter has an overall length of 12.92 meters (42 feet, 4.7 inches) and height of 3.09 meters (10 feet, 1.7 inches). The SA 315B has an empty weight of 1,021 kilograms (2,251 pounds) and a maximum gross weight of 1,950 kilograms (4,299 pounds). With an external load carried on its cargo hook, the maximum gross weight is 5,070 pounds (2,300 kilograms).
The three-bladed, fully-articulated main rotor has a diameter of 11.02 meters (36 feet, 1.9 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 three-bladed anti-torque tail rotor is 1.91 meters (6 feet, 3.2 inches) in diameter and turns clockwise, as seen from the helicopter’s left side. (The advancing blade is below the axis of rotation.) It turns at 2,020 r.p.m.
The Lama was initially powered by a Turboméca Artouste IIIB (later aircraft, Artouste IIIB1) turbo-moteur. This is a turboshaft engine with a two-stage compressor section (1 axial-flow, 1 centrifugal-flow stages), and a three-stage axial-flow turbine. The engine turns 33,500 r.p.m. and the output drive shaft turns 5,773 r.p.m. The Artouste IIIB1 produces a maximum 870 horsepower, but is derated to 570 horsepower for installation in the Lama. The engine is 1.815 meters (5 feet, 11.5 inches) long, 0.667 meters (2 feet, 2.3 inches) high and 0.520 meters (1 foot, 8.5 inches) wide. It weighs 178 kilograms (392 pounds).
The helicopter has a cruise speed 103 knots (191 kilometers per hour, 119 miles per hour) and a maximum speed of 113 knots (209 kilometers per hour, 130 miles per hour) at Sea Level. The service ceiling is 5,400 meters (17,717 feet). At 1,950 kilograms (4,299 pounds), the Lama has a hover ceiling in ground effect (HIGE) of 5,050 meters (16,568 feet), and out of ground effect (HOGE), 4,600 meters (15,092 feet).
Société nationale des constructions aéronautiques du Sud-Est became Aérospatiale in 1970. The company produced the SA 315B Lama beginning in 1971. It was also built under license by Hundustan Aeronautics in India and Helibras in Brazil.
The total number of SA 315Bs and its variants built is uncertain. In 2010, Eurocopter, the successor to Aérospatiale, announced that it will withdraw the Lama’s Type Certificate in 2020.
After setting the world altitude record, 315-001 was returned to the standard configuration and assigned registration F-BPXS. It crashed at Flaine, a ski resort in the French Alps, 23 February 1985.
Jean Ernest Boulet was born 16 November 1920, in Brunoy, southeast of Paris, France. He was the son of Charles-Aimé Boulet, an electrical engineer, and Marie-Renée Berruel Boulet.
He graduated from Ecole Polytechnique in 1940 and the Ecole Nationale Supérieure de l’aéronautique In 1942. (One of his classmates was André Edouard Turcat, who would also become one of France’s greatest test pilots.)
Following his graduation, Boulet joined the Armée de l’Air (French Air Force)and was commissioned a sous-lieutenant. He took his first flight lesson in October. After the surrender of France to the Nazi invaders, Boulet’s military career slowed. He applied to l’Ecole Nationale Supérieure de l’Aéronautique in Toulouse for post-graduate aeronautical engineering. He completed a master’s degree in 1943.
During this time, Boulet joined two brothers with LaResistance savoyarde, fighting against the German invaders as well as French collaborators.
In 1943, Jean Boulet married Mlle. Josette Rouquet. They had two sons, Jean-Pierre and Olivier.
In February 1945, Sous-lieutenant Boulet was sent to the United States for training as a pilot. After basic and advanced flight training, Bouelt began training as a fighter pilot, completing the course in a Republic P-47D Thunderbolt. He was then sent back to France along with the other successful students.
On 1 February 1947 Jean Boulet joined Société nationale des constructions aéronautiques du Sud-Est (SNCASE) as an engineer and test pilot. He returned to the United States to transition to helicopters. Initially, Boulet and another SNCASE pilot were sent to Helicopter Air Transport at Camden Central Airport, Camden, New Jersey, for transition training in the Sikorsky S-51. An over-enthusiastic instructor attempted to demonstrate the Sikorsky to Boulet, but lost control and crashed. Fortunately, neither pilot was injured. Boulet decided to go to Bell Aircraft at Niagara Falls, New York, where he trained on the Bell Model 47. He was awarded a helicopter pilot certificate by the U.S. Federal Aviation Administration, 23 February 1948.
As a test pilot Boulet made the first flight in every helicopter produced by SNCASE, which would become Sud-Aviation and later, Aérospatiale (then, Eurocopter, and now, Airbus Helicopters).
While flying a SE 530 Mistral fighter, 23 January 1953, Boulet entered an unrecoverable spin and became the first French pilot to escape from an aircraft by ejection seat during an actual emergency. He was awarded the Médaille de l’Aéronautique.
Jean Boulet was appointed Chevalier de la légion d’honneur in 1956, and in 1973, promoted to Officier de la Légion d’honneur.
Jean Boulet had more than 9,000 flight hours, with over 8,000 hours in helicopters. He set 24 Fédération Aéronautique Internationale world records for speed, distance and altitude. Four of these are current.
Jean Boulet wrote L’Histoire de l’Helicoptere: Racontée par ses Pionniers 1907–1956, published in 1982 by Éditions France-Empire, 13, Rue Le Sueuer, 75116 Paris.
Jean Ernest Boulet died at Aix-en-Provence, in southern France, 15 February 2011, at the age of 90 years.

31 May 1955: Test Pilot Jacqueline Marie-Thérèse Suzanne Douet Auriol flew the Dassault MD.454 Mystère IV N to a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a 15/25 Kilometer Straight Course at Brétigny-sur-Orge, France.¹ Her average speed of 1,151 kilometers per hour (715 miles per hour)—0.94 Mach—broke the previous record which had been set two years earlier by her friend, Jacqueline Cochran.
Jacqueline Auriol was awarded the Harmon International Trophy for 1955, the third of four that she would receive.
The Société des Avions Marcel Dassault MD.454 Mystère IVN 01 was the first of two prototype two-place, single-engine, swept-wing interceptors. 01 was first flown 19 July 1954 by test pilot Gérrard Muselli. It had a large air-search radar mounted over the intake and was armed with 52 rockets carried in a retractable tray in the belly, very similar to the North American Aviation F-86D Sabre. The fuselage had been lengthened over the single-seat Mystère IV to provide space for the second cockpit.
The Mystère IVN was 49 feet, 11 inches (15.215 meters) long with a wingspan of 37 feet, 6 inches (11.430 meters) and overall height of 15 feet, 1 inch (4.597 meters). Its empty weight was 15,741 pounds (7,140 kilograms) and maximum takeoff weight was 22,572 pounds (10,238 kilograms).
The Mystère IV N was powered by a Rolls-Royce Avon RA.7R axial flow, afterburning turbojet engine. It used a 12-stage compressor, 8 combustion chambers and 2-stage turbine. It produced 9,500 pounds of thrust (42.258 kilonewtons) at 7,800 r.p.m., with afterburner. The engine was 42.2 inches (1.072 meters) in diameter, 276 inches (7.010 meters) long and weighed 2,960 pounds (1,343 kilograms).
Jacqueline Auriol’s record-setting Dassault Mystère IV N 01 F-ZXRM is on display at the Conservatoire l’Air et l’Espace d’Acquitane, Bordeaux Merignac Airport, France.
1 April 1921: Adrienne Bolland, a pilot employed by René Caudron to demonstrate his airplanes in South America, flew a Caudron G.3 from Mendoza, Argentina to Santiago, Chile, across the Andes Mountain Range.
Mlle Bolland’s route followed the Paso de Upsallata, passing south of Aconcagua, at 6,960.8 meters (22,837 feet), the highest mountain in the Andes, and north of Volcan Tupangato, 6,570 meters (21,580 feet). The duration of the flight was 4 hours, 17 minutes.
Bolland was awarded a gold medal by the Argentine League of Patriots at Buenos Aires.
FLIGHT reported:
Mdlle. Bolland Crosses the Andes
From a Daily Mail report Mdlle. Bolland, the French aviatress, on April 1, left Mendoza, Argentina, at 7.30, and flew over the Andes Mountains, arriving at Santiago in Chile, just three hours later.
This the second time Mdlle. Bolland has flown over the Andes.
The distance Mdlle. Bolland covered was about 112 miles. There are heights of more than 20,000 ft. in the neighborhood of the point at which she crossed the range.
We are just wondering whether the journey was a “non-stop” one, with strong headwinds, or whether a halt was made en route, and if the latter, where.
—FLIGHT The Aircraft Engineer and Airships, No. 641 (No. 14, Vol. XIII.), 7 April 1921, at Page 250, Column 2
Adrienne Armande Pauline Boland was born at Arcueil, a suburb of Paris, France, 25 November 1895. She was the youngest of seven children of writer Henri André Joseph Boland and Marie Amélie Elisabeth Françoise Allonie (Marie Joséphine) Pasques. Her father died in 1909, and her mother sometime later.
At the age of 24, she decided to learn to fly and enrolled in flight training at Société des Avions Caudron (the Caudron Airplane Company), Le Crotoy. She started training 16 November 1919 and was awarded her pilot’s license 29 January 1920. An error on the certificate spelled her surname with two “l”s, and she retained the name “Bolland” for the rest of her life.
Mlle Bolland was employed by René Caudron to transport airplanes to and from the factory. She told Caudron that she wanted her own airplane. He told her that if she could perform a loop in a Caudron G.3, a pre-World War I scout plane, that she could fly it for the company. She did, and was then asked to fly it across the English Channel, which she did, 25 August 1920.
Caudron sent her to Argentina to demonstrate his airplanes. Once there, she planned to fly across the Cordillera de los Andes (the Andes Mountain Range) to Chile on the western coast of South America. The mountains were higher than the airplane was capable of flying, so she had to fly through valleys to find a way across. Departing Mendoza, Argentina at 6:00 a.m, she headed across the 400-kilometer (250 miles) wide mountain range. Most of the flight was at an altitude of 4,500 meters (14,764 feet) and it was extremely cold. Without maps, she succeeded: “Suddenly I saw a break in the mountains. . . and in the distance, the plain of Chile. I was saved.”
The airplane was sold in Santiago and Bolland returned to Buenos Aires by train.
After returning to France, Mlle Bolland was a frequent participant at air meets, displaying her skills in aerobatics. She flew two Caudron C.27s, G-AGAP (c/n 5533.7) and F-AGAQ (c/n 5534.8), both registered in her name 27 February 1924. At the Aérodrome d’Orly, Paris, on 27 May 1924, she took off at 4:12 p.m., completed 212 consecutive loops, then landed at 5:25 p.m. (The Caudron C.27 was redesignated C.127 in late 1924.)
In 1924, France named Adrienne Bolland Chevalier de la légion d’honneur for her flight across the Andes.
Ernest Jean Baptiste Charles Vinchon married Mlle Bolland in Paris, 15 March 1930.
After the surrender of France to Nazi Germany in 1940, M. and Mme Vichon remained in occupied France and became agents of the Confrérie Notre-Dame (CND, or Brotherhood of Notre Dame, later called CND-Castile), an intelligence organization of the Forces françaises libres (Free French Forces).
For her services during World War II, in 1947 Mme Vichon was advanced to the rank of Officier de la Légion d’honneur.
Adrienne Bolland Vichon died at Paris, France, 18 March 1975 at the age of 79 years. She was buried in Donnery, Loiret.
Adrienne Bolland crossed the Andes in a Caudron G.3, c/n 4902, registered F-ABEW. 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.
The Caudron G.3 was 6,40 meters (20 feet, 11.6 inches) long with an upper wingspan of 13,40 meters (43 feet, 11.6 inches). The height of the aircraft was 2,60 meters (8 feet, 6.6 inches). The G.3 had an empty weight of 355 kilograms (783 pounds) and maximum gross weight of 630 kilograms (1,389 pounds).
The G.3 was powered by an air-cooled, normally-aspirated 10.910 liter (665.791 cubic inches) Société des Moteurs Gnome et 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 cruising speed of 80 kilometers per hour (50 miles per hour) maximum speed of 95 kilometers per hour (59 miles per hour) at 100 meters (328 feet) and service ceiling of 4,300 meters (14,108 feet).
