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.

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.

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.

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

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).

25 July 1915

Captain Lanoe George Hawker, V.C., D.S.O., Royal Engineers and Royal Flying Corps (Imperial War Museum Catalog number Q 61077

25 July 1915: Near Passchendaele, Belgium, Captain Lanoe George Hawker, DSO, No. 6 Squadron, Royal Flying Corps, was flying a single-engine Bristol Scout C, which he had had his mechanic equip with a single Lewis machine gun, fixed and firing 45° to the left to avoid the propeller arc.

Captain Hawker saw three enemy aircraft and attacked, shooting down all three. For this action, Captain Hawker was awarded the Victoria Cross. He was the third pilot, and the first ace, to receive Britain’s highest award for gallantry in combat.

     His Majesty the KING has been graciously pleased to award the Victoria Cross to the undermentioned Officers, Non-commissioned Officer and man, in recognition of their most conspicuous bravery and devotion to duty in the field:—

Captain Lanoe George Hawker, D.S.O., Royal Engineers and Royal Flying Corps.

     For most conspicuoius bravery and very great ability on 25th July, 1915.

     When flying alone he attacked three German aeroplanes in succession. The first managed to eventually escape, the second was driven to the ground damaged, and the third, which he attacked at a height of about 10,000 feet, was driven to the earth in our lines, the pilot and observer being killed.

     The personal bravery shown by this Officer was of the very highest order, as the enemy’s aircraft were armed with machine guns, and all carried a passenger as well as the pilot.

The London Gazette, Number 29273, 24 August 1915, at Page 8395, Column 1.

Hawker was credited with destroying 7 enemy aircraft in combat. His luck came to an end, however, on 23 November 1916, when he encountered Leutnant Manfred Albrecht Freiher von Richthofen of Jagdstaffel 2 near Begaume, France, while flying an Airco DH.2.

A lengthy battle ensued with neither fighter ace gaining advantage. Richthofen, “The Red  Baron,” fired over 900 rounds during the fight. Running low on fuel, Hawker tried to break off and head for friendly lines. Almost there, he was struck in the head by a single machine gun bullet from Richthofen’s Albatros D.II. Major Hawker was killed and his airplane spun to the ground. He was the eleventh of Baron Richthofen’s eighty aerial victories.

The Baron took one of Hawker’s machine guns as a trophy.

The Bristol Scout C was a single-place, single-engine tractor-type biplane reconnaissance aircraft. It was manufactured by the British and Colonial Aeroplane Co., Ltd., at Brislington, south east of Bristol, England. The Scout C was 20 feet, 8 inches (6.299 meters) long with a wingspan of 24 feet, 7 inches (7.493 meters) and height of 8 feet, 6 inches (2.591 meters). The wings had a chord of 4 feet, 6 inches (1.372 meters) and vertical separation of 4 feet, 3 inches (1.295 meters). They were staggered 1 foot, 4½ inches (0.419 meters). The Scout C had an empty weight of 757 pounds (343 kilograms) and maximum gross weight of 1,195 pounds (542 kilograms).

The Scout C was powered by an air-cooled, normally-aspirated, 10.91 liter (665.79 cubic inch) Société des Moteurs Le Rhône 9C nine-cylinder rotary engine which produced 83 horsepower at 1,285 r.p.m. The engine turned a two-bladed, fixed-pitch wooden propeller through direct drive.

The Scout C had a maximum speed of 92.7 miles per hour (149.2 kilometers per hour) at ground level, and 86.5 miles per hour (139.2 kilometers per hour) at 10,000 feet (3,048 meters). It could climb to 10,000 feet in 21 minutes, 20 seconds. Its service ceiling was 15,500 feet (4,724 meters). It carried sufficient fuel to remain airborne for 2½ hours.

A total of 374 Bristol Scouts were built. 211 of these were of the Scout C variant.
