The Hydroavian is 8.45 meters (27 feet, 8.67 inches) long with a wingspan of 14 meters (45 feet, 11.18 inches) and height of 3.70 meters (12 feet, 1.67 inches). It has an empty weight of 380 kilograms (838 pounds) and the gross weight is 475 kilograms (1,047 pounds).

Fabre’s airplane was powered by a normally-aspirated, air-cooled, 7.983 liter (487.140-cubic-inch-displacement) Société des Moteurs Gnome Omega 7-cylinder rotary engine which produced 50 horsepower at 1,200 r.p.m. The direct-drive engine turned a two-bladed wooden propeller in a left-hand, pusher configuration. The Omega 7 is 79.2 centimeters (2 feet, 7.2 inches) long, 83.8 centimeters (2 feet, 9.0 inches) in diameter, and weighs 75.6 kilograms (166.7 pounds). The prototype of this engine is in the collection of the Smithsonian Institution National Air & Space Museum.

Though it was damaged in a crash in 1911, Le Canard was restored and is in the collection of Musée de l’air et de l’espace.

22 February 1912: At 4:06 a.m., at the Aerodrome Deperdussin, Pau, France, Jules Charles Toussaint Védrines took off in the 1912 Société de Production des Aéroplanes Deperdussin (SPAD) Monoplane, and began to fly it around a 5 kilometer (3.1 miles) course, to cover a total distance of 200 kilometers (124.3 miles). The flight was timed by M. Maurice Martin.

Védrines’ time at 50 kilometers (31.07 miles) was 19 minutes, 3-4/5 seconds, for an average speed of 157.37 kilometers per hour (97.79 miles per hour); at 100 kilometers (63.14 miles), 37 minutes 58-2/5 seconds, 159.44 km/h (99.07 miles per hour); 150 kilometers (93.21 miles), 56 minutes, 41-2/5 seconds, 158.76 kilometers per hour (98.65 miles per hour); and 200 kilometers (124.27 miles), 1 hour, 15 minutes, 20-4/5 seconds, 159.26 kilometers per hour (98.96 miles per hour).¹

Various sources (e.g., Wikipedia) credit Jules Védrines with having made the first flight at a speed of 100 miles per hour, although his highest average speed, measured at the 100 kilometer mark, was actually a fraction of a mile per hour less.

The Deperdussin monoplane was 7.0 meters (22 feet, 11.6 inches) long, with a wingspan of 6.25 meters (20 feet 6.1 inches) and height of 2.30 meters (7 feet, 6.6 inches). Its wing area was 9.3 square meters (100.1 square feet).

It was powered by an air-cooled Société des Moteurs Gnôme Lambda Lamda two-row, 14-cylinder rotary engine rated at 140 horsepower, driving a two-bladed Chauvière Hélice Intégrale propeller, with a diameter of  2.50 meters (8 feet, 2.4 inches).

23 October 1911: For the first time, the airplane is used in warfare. Capitán Carlo Maria Piazza, a pilot commanding an aviation unit of the Regio Esercito (the Italian Royal Army), flew a Blériot Type XI on a reconnaissance mission over the Zanzur oasis, south west of Tripoli, Libya, during the Italo-Turkish War (1911–1912).

Aviation author Walter J. Boyne wrote that, “The world’s first combat flight took place on October 23, when the Commander of the Air Fleet, Captain Piazza, took off at 6:19 a.m. to reconnoiter Turkish positions. In a sixty-one minute flight, he discovered several enemy encampments. . . .”

The Influence of Air Power Upon History, Walter J. Boyne, Pen & Sword Books Limited, 2005, at Page 37.

The Blériot XI was a single-seat, single-engine monoplane, designed by Raymond Saulnier and built by Louis Charles Joseph Blériot. It was 24 feet, 11 inches (7.595 meters) long with a wingspan of 27 feet, 11 inches (8.509 meters) and overall height of 8 feet, 10 inches (2.692 meters). It had an empty weight of 507 pounds (229.9 kilograms).

(Sources give conflicting specifications for the Blériot XI, probably because they were often changed in an effort to improve the airplane. Dimensions given here are from the three-view drawings, below.)

(Flight, No. 149., Vol. III, No. 44, 4 November 1911, at Page 967)

In its original configuration, the Type XI was powered by an air-cooled, 3.774 liter (230.273 cubic inches) Robert Esnault-Pelterie (R.E.P.) two-row, seven-cylinder fan engine (or “semi-radial”), which produced 30 horsepower at 1,500 r.p.m., and drove a four-bladed paddle-type propeller. The R.E.P. engine weighed 54 kilograms (119 pounds). This engine was unreliable and was soon replaced by an Alessandro Anzani & Co. W-3.

The Blériot XI Militaire was powered by a normally-aspirated, air-cooled, 7.983 liter (487.140-cubic-inch-displacement) Société des Moteurs Gnome Omega 7-cylinder rotary engine which produced 50 horsepower at 1,200 r.p.m. The direct-drive engine turned a two-bladed wooden propeller in a left-hand, tractor configuration. The Omega 7 is 79.2 centimeters (2 feet, 7.2 inches) long, 83.8 centimeters (2 feet, 9.0 inches) in diameter, and weighs 75.6 kilograms (166.7 pounds). The prototype of this engine is in the collection of the Smithsonian Institution National Air & Space Museum.

The Blériot XI had a maximum speed of 76 kilometers per hour (47 miles per hour) and its service ceiling was 1,000 meters (3,281 feet).

Captain Piazza was killed in action in 1917, during the First World War.

23 September 1913: Pioneering aviator Eugène Adrien Roland Georges Garros (6 October 1888–5 October 1918) was the first pilot to fly across the Mediterranean Sea.

At 5:47 a.m., he departed Fréjus, Côte d’Azur, France, in a Morane-Saulnier G and flew to Bizerte, Tunisia, 470 miles (756 kilometers) to the south-southeast. He arrived at 1:40 p.m., having been airborne 7 hours, 53 minutes.

Garros flew on to Kassar Said Aerodrome the following day. His airplane was then dismantled and shipped back to France.

On 15 October 1913, Roland Garros was appointed Chevalier de la légion d’honneur.

The Aéroplanes Morane-Saulnier Type G was a two-place, single-engine monoplane, which had first flown in 1912. The airplane used wing-warping for roll control. It’s landing gear consisted of two wheels and a tail skid. The wooden framework was primarily ash and was covered in fabric. The airplane was 21 feet, 6 inches (6.553 meters) long with a wingspan of 30 feet, 6 inches (9.296 meters). The wing had a chord of 6 feet, 0 inches (1.829 meters), no dihedral, and the wingtips were swept. The airplane had an empty weight of 680 pounds ( 308 kilograms) and a maximum weight of 1,166 pounds (529 kilograms).

The pilot’s instrument panel had a revolution indicator (tachometer), a barograph, and a compass.

The Morane-Saulnier G was powered by an air-cooled 11.835 liter (722.22 cubic inches) Société des Moteurs Gnome Lamda seven-cylinder rotary engine with a single Bosch magneto, with a nominal rating of 80 horsepower (one source indicates that the engine actually produced 67.5 horsepower at 1,250 r.p.m.), and driving a laminated walnut Chauvière Hélice Intégrale fixed-pitch propeller which had a diameter of 7 feet, 10 inches (2.570meters).

The airplane had a 14 gallon ¹ (63.65 liters) main fuel tank near the engine, and a second 8 gallon (36.37 liters) tank in the cockpit. Fuel had to be transferred forward by using a hand-operated pump. A 5 gallon (22.73 liters) tank for lubricating oil was adjacent to the main fuel tank.

Garros’ airplane maintained an average speed of 59.5 miles per hour (96 kilometers per hour) for this flight. The Morane-Saulnier G had a maximum speed of 76 miles per hour (122 kilometers per hour).

The Morane-Saulnier G was produced under license by Grahame-White Aviation Company, Hendon Aerodrome, London, England, and by Dux at Moscow, Russia. More than 150 Type Gs were built.

Roland Garros was born 6 October 1888 at Saint-Denis, Réunion (an island in the Indian Ocean). He was the son of Antoine Georges Garros and Maria Clara Emma Faure Garros. Garros was a racer and test pilot who had set many aviation records, including a Fédération Aéronautique Internationale World Altitude Record of 5,610 meters (18,406 feet), set 11 September 1912 at Saint-Brieuc, France. ²

Garros flew in World War I as a fighter pilot for France and shot down a total four enemy airplanes. Garros’ airplane went down behind enemy lines and he was captured, 18 April 1915. He escaped nearly three years later and returned to France. For his military service, he was promoted to Officier de la Légion d’honneur, 6 March 1917. He was also awarded the Croix de Guerre.

Lieutenant d’infantrie Eugène Adrien Roland Georges Garros, Officier de la Légion d’honneur, Aéronautique Militaire, flying a SPAD S.XIII C.1, Nº. 15403, was shot down by the German ace, Leutnant Hermann Habich, near Vouziers, France, 5 October 1918. He was killed one day before his 30th birthday.

Stade Roland Garros in Paris, the tennis stadium where the French Open is held, was named in honor the pioneering aviator.

9 September 1913 (27 August 1913, Old Style ¹): At the Syretsky military airfield west of Kiev, Ukraine, Imperial Russia, Пётр Николаевич Нестеров (Pyotr Nikolayevich Nesterov), a military officer, flew a Nieuport IV.G into an inside loop, the first time this aerobatic maneuver had ever been performed.

Nesterov’s Loop

Also known as “Nesterov’s Loop,” or a “dead loop,” the inside loop was completed by entering from a dive, pulling the nose up and flying in a closed curve in the vertical plane (with the top of the airplane toward the center of the loop at all times), and then returning to a dive.

This maneuver is now performed beginning and ending in straight and level flight, but airplanes of the time had insufficient power.

The airplane flown by Lieutenant Nesterov was a Nieuport IV, designed by the French aircraft company, Société Anonyme des Éstablissements Nieuport, and built in Russia by several manufacturers. The variant flown by the Imperial Russian Air Service was powered by an air-cooled, normally-aspirated, 10.292 liter (628.048 cubic inch displacement Société des Moteurs Gnome Gamma seven-cylinder rotary engine, which produced 70 horsepower at 1,200 r.p.m.

“. . . I sat head down for a few moments and did not feel rush of blood to the head, I was sitting tightly, and legs pressed on the pedal … Tools in the open boxes remained in their places. Gasoline and oil also keeps the centrifugal force at the bottom of the tank, ie, at the top, and normally fed to the engine, which worked perfectly the entire upper half of the loop. In general, all this proves that the airplane made ​​regular rotation, only in the vertical plane, as all the time there was a dynamic equilibrium. With this only turning the air is defeated by man. . . . Man mistakenly forgot that in the air the support is everywhere, and he should cease to determine the direction in relation to the earth. “

One year later, 8 September 1914 (25 August 1914, Old Style), Nesterov became the first pilot to destroy an enemy aircraft in aerial combat. Flying a Morane Saulnier Type G near Zhovkva, Ukraine, Nesterov rammed an Albatros B.II. Both aircraft were so badly damaged that they crashed. The Austrian pilot, Franz Malina, and observer, Baron Friederich von Rosenthal, were both killed. Nesterov died of injuries the following day.
