25 July 1984

Svetlana Evgenievna Savitskaya, Hero of the Soviet Union

25 July 1984: Cosmonaut Svetlana Evgenievna Savitskaya, on her second mission to the Salyut 7 space station, became the first woman to perform a space walk, when she spent 3 hours, 35 minutes outside the space station.

Colonel Savitskaya was the second woman to fly in space, following Cosmonaut Valentina Vladimirovna Tereshkova. Svetlana Evgenievna’s first space flight was also to Salyut 7, in 1982. She was assigned as commander of an all-woman crew to the station, but that flight was cancelled. She has spent 19 days, 7 hours, 6 minutes in space.

Svetlana Evgenievna Savitskaya was born 8 August 1948 in Moscow, Russia. She is the daughter of Air Marshal Yevgeny Yakovlevich Savitsky, twice a Hero of the Soviet Union, and Lidia Pavlovna.

Colonel Savitskaya is a retired flight engineer and test pilot. Like her father, she was twice awarded the title Hero of the Soviet Union. She was also awarded the Order of Lenin twice, the Order of the Badge of Honor, and the Order for Services to the Fatherland.

Svetlana Evgenievna was a member of the Soviet Union’s national aerobatic team. In 1970, she won the Fédération Aéronautique Internationale (FAI) World Aerobatic Championship, held at RAF Hullvington, Wiltshire, England, while flying a Yakovlev Yak-18.

In 1971, she graduated from the Central Flight Technical School of the USSR, and from the Ministry of Aviation Industry test pilot school, in 1976. She served as a flight instructor until 1978 when she was assigned as a test pilot at the Yakovlev Design Bureau. She set 18 FAI world records in airplanes and another 4 in free-fall parachuting from high altitude. (Two records, set with a Yakovlev Yak-40 in April 1981, remain current.)

In 1980, Svetlana Evgenievna was assigned to cosmonaut training.

She earned her doctorate in technical sciences in 1986. Married to a pilot, Victor Khatovsky, with a son, Konstantine. She retired in 1993 with the rank of major. (Presently she holds the rank of colonel.)

Academician Savitskaya is a member of the International Academy of Astronautics. She is Honorary President of the Federation of Aviation Sports of Russia.

Svetlana Evgenievna currently serves in the parliamentary assembly of the Union of Russia and Belarus. She holds the position of Deputy Chairman of the committee for security, defense and law enforcement.

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.

25 July 1909

Starting the Anzani engine of Louis Blériot’s Type XI monoplane, 25 July 1909. (Library of Congress)

25 July 1909: At 4:41 a.m., Louis Charles Joseph Blériot took of from the hamlet of les Baraques,¹ near Sangatte, Pas-de-Calais, France, in his own Type XI single-engine monoplane, and flew across the English Channel (la Manche) to Dover. He landed at Northfall Meadow, near Dover Castle, Kent, England.

The airplane did not have a compass, so for a visual reference. Blériot used a 26-knot Pertuisane-class torpedo boat destroyer, Escopette, which was sailing toward Dover.  After passing the ship, visibility deteriorated and he was only able to see the water below him.

Blériot flew on and after about ten minutes was able to see the coastline ahead. He realized that the wind had blown him to the east of his intended course, so he flew along the shoreline until he recognized a signal marking the landing point. The wind was gusty near the cliffs and he landed harder than intended, slightly damaging his airplane.

A contemporary aviation news publication reported:

. . . Accounts differ as to the exact moment of departure and descent, and as a matter of fact it is doubtful if any reliable timing was made since M. Bleriot started without a watch as well as without a compass. The distance of the flight was about 31 miles, and hence the speed was in the region of 45 miles an hour. During the crossing he flew at an altitude of 150 ft. to 300 ft., and thus kept much nearer the water than Mr. Latham did on his attempt.

This was the first time an airplane had been flown across the English Channel, and brought Blériot international acclaim. He was appointed Chevalier de la légion d’honneur, by France. A London newspaper, the Daily Mail, awarded him a £1,000 prize.

Very quickly, orders for his Type XI were coming in. Between 1909 and 1914, approximately 900 were sold.

Louis Bleriot’s Channel-crossing Type XI monoplane was donated to the Musée des arts et métiers in Paris by the newspaper Le Matin, in October 1909. It remains in the museum’s permanent collection.

Louis Charles Joseph Blériot was born 1 July 1872 at Cambrai, Nord, Pas-de-Calais, France. He was the son of Louis Charles Pierre Alexander Blériot and Clémence Marie Eugenie Candeliez Blériot. In 1882 Blériot was sent to l’Institution Notre-Dame de Grâce, a boarding school in Cambrai, and then, to a high school in northern France. He next studied at the Collège Sainte-Barbe in Paris. After a year there, he transferred to the École Centrale Paris, at Châtenay-Malabry, in southwest Paris.

In 1895–1896, Blériot served as a sous-lieutenant assigned to the 24ᵉ régiment d’artillerie (24th Regiment of Artillery) at Tarbes in the Pyrenees mountains, which divide France from Spain.

Blériot next worked as an electrical engineer and in 1896, he invented acetylene headlamps for use on automobiles. Blériot gained an interest in aviation after attending l’Exposition de Paris 1900. The income from his lamp manufacturing allowed him to conduct serious aeronautical experiments.

In 1901, Blériot married Mlle. Jeanne Alicia Védere (the marriage banns were published 2 February 1901). They would have six children, born between 1902 and 1929.

Over the next few years, worked with several other pioneers of aviation, including Ernest rchdeacon,  Léon Levavasseur, Gabriel Voison, Eventually, he started his own aeronautical research and aircraft manufacturing company, Recherches Aéronautique Louis Blériot. In 1913, he bought the aircraft manufacturing company that would become Société Pour L’Aviation et ses Dérivés, designers and builders of the legendary fighter of World War I, the SPAD S.XIII C.1. His businesses in France and England manufactured airplanes, automobiles and motorcycles.

In 1930, Blériot established the Blériot Trophy, to be awarded to an aviator who demonstrated flight at a speed of 2,000 kilometers per hour (1,242.742 miles per hour) for 30 minutes. 31 years later, 10 May 1961, the three-man crew of a Convair B-58A Hustler named The Firefly accomplished that feat.

Louis Charles Joseph Blériot died 2 August 1936, in Paris. He was buried at the Cimitière des Gonards, Versailles, Île-de France, France.

Louis Bleriot flew this airplane across the English Channel 25 July 1909. It was donated to the Musée des arts et métiers by the French newspaper, Le Matin, in October 1909. (Musée des arts et métiers)

The Blériot XI was a single-seat, single-engine monoplane. It was 26.24 feet (7.998 meters) long with a wingspan of 25.35 feet (7.727 meters) and height to the top of the cabane strut of 8.0 feet (2.438 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. The model flown across the English Channel was described by Flight as the Blériot Short-Span Monoplane. Dimensions given here are from the three-view drawings, below.)

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 Anzani W-3 was an air-cooled, naturally-aspirated, 3.377 liter (206.078 cubic inch) 60° (some sources state 55°) three-cylinder “fan”-type radial engine (or W-3). It was a direct-drive, right-hand-tractor engine which produced 25 horsepower at 1,600 r.p.m. The W-3 was 0.300 meters (11.811 inches) long, 0.386 meters (15.197 inches) high, and 0.694 meters (2 feet, 3.323 inches) wide. The engine weighed 65 kilograms (143 pounds). The engine turned a highly-efficient Hélice Intégrale Chauvière two-bladed, fixed-pitch, propeller which had a diameter of 6 feet, 8 inches (2.032 meters). The Anzani W-3 cost 3,000 French francs in 1909.

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

A description of the Blériot Type XI appeared in Vehicles of the Air, by Victor Loughead,² Second Edition, The Reilly and Britton Co., Chicago, 1910, Figure 197, between Pages 406 and 407:

24 July 1950: The first rocket launch at Cape Canaveral, Florida, took place. Bumper 8 was a two-stage rocket consisting of a captured German V-2 ballistic missile as the first stage and a WAC Corporal sounding rocket as the upper, second, stage. The rocket lifted off from Launch Complex 3 at the Cape Canaveral Air Force Station and followed a ballistic trajectory over the Joint Long Range Proving Ground. This was a low-angle atmospheric flight. The WAC Corporal reached an altitude of 10 miles (16.1 kilometers) and traveled 200 miles (322 kilometers) downrange.

The Bumper Project was a U.S. Army Ordnance Corps program, with overall responsibility contracted to the General Electric Corporation. The V-2s used in the Bumper Project were modified at accept the WAC Corporal second stage. Compressed air was used to separate the stages after the V-2 engine was cut off.

The V2, or Vergeltungswaffen 2 (also known as the A4, Aggregat 4) was a ballistic missile weighing 28,000 pounds (12,500 kilograms) when fully loaded. It carried a 2,200 pound (1,000 kilogram) explosive warhead of amatol, a mixture of TNT and ammonium nitrate. Propellant was a 75/25 mixture of of ethanol and water with liquid oxygen as oxidizer.

When launched, the rocket engine burned for 65 seconds, accelerating the rocket to 3,580 miles per hour (5,761 kilometers per hour) on a ballistic trajectory. The maximum range of the rocket was 200 miles (322 kilometers) with a peak altitude between 88 and 128 miles (142–206 kilometers), depending on the desired range. On impact, the rocket was falling at 1,790 miles per hour (2,881 kilometers per hour).

The V-2 could only hit a general area and was not militarily effective. Germany used it against England, France, The Netherlands and Belgium as a terror weapon. More than 3,200 V-2 rockets were launched against these countries.

At the end of World War II, many V-2 rockets and components were captured by Allied forces and were brought to the United States for research, along with many of the German engineers, scientists and technicians who had worked on the German rocket program. Others were captured by the Soviet army.

The WAC Corporal was a liquid-fueled hypergolic rocket. After separation from the first stage, the WAC Corporal was capable of reaching more than 80 miles (129 kilometers). It was designed by the Jet Propulsion Laboratory in Pasadena, California, and built by Douglas Aircraft. The rocket carried small research packages into the upper atmosphere. The two-stage rocket was used to develop launch techniques and to refine the separation of upper stages at very high speed.

Now named the Kennedy Space Center, but known simply as “The Cape,” the location was selected to allow rocket testing to take place over the Atlantic Ocean, minimizing danger to persons and property. As one of the points within the United States closest to the Equator, rockets launched on an eastward trajectory receive additional velocity due to the Earth’s rotation.

24 July 1936: On her 39th birthday, at the Union Air Terminal, Burbank, California, Amelia Earhart accepted delivery of her new Lockheed Electra 10E Special, registered NR16020.

$80,000 to buy the Electra was provided by the Purdue Research Foundation from donations made by several individuals. George Palmer Putnam, Amelia’s husband, made the arrangements to order the airplane and in March 1936 gave Lockheed the authorization to proceed, with delivery requested in June.

The Electra Model 10 was manufactured by the Lockheed Aircraft Company at Burbank, California. It was an all-metal, twin-engine, low-wing monoplane with retractable landing gear, designed as a small, medium-range airliner. In the standard configuration it carried a crew of 2 and up to 10 passengers. The Model 10 was produced in five variants with a total of 149 airplanes built between August 1934 and July 1941. Lockheed built fifteen Model 10Es. Earhart’s was serial number 1055.

Earhart’s Electra was equipped with a Western Electric Model 13C radio transmitter and Model 20B receiver for radio communication. It used a Sperry GyroPilot gyroscopic automatic pilot. Additional modifications included four auxiliary fuel tanks in the passenger compartment, a navigator’s station to the rear of that, elimination of passenger windows, installation of the autopilot, navigation equipment and additional batteries. These modifications varied from the standard airplane enough that it was restricted to carrying only members of required flight crew. This was denoted by the letter “R” in the airplane’s registration.

The Electra was not ready until mid-July. Earhart first flew the new airplane on 21 July with Lockheed test pilot Elmer C. McLeod.

The Electra 10E was 38 feet, 7 inches (11.760 meters) long with a wingspan of 55 feet (16.764 meters) and overall height of 10 feet, 1 inch (3.074 meters). The standard Model 10 had and empty weight of 6,454 pounds (2,927.5 kilograms) and a gross weight of 10,500 pounds (4,762.7 kilograms). NR16020 had an empty weight of 7,265 pounds (3295.4 kilograms). Lockheed’s performance data was calculated using 16,500 pounds (7,484.3 kilograms) as the Maximum Takeoff Weight.

NR16020 had a total fuel capacity of 1,151 gallons (4,357 liters) in ten tanks in the wings and fuselage. 80 gallons (302.8 liters) of lubricating oil for the engines was carried in four tanks.

Earhart’s Electra 10E Special was powered by two air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S3H1 nine-cylinder radial engines, with a compression ratio of 6:1. These engines used a single-stage centrifugal supercharger and were rated at 550 horsepower at 2,200 r.p.m. at 5,000 feet (1,524 meters) and 600 horsepower at 2,250 r.p.m. for take off. The direct-drive engines turned 9 foot, 7/8-inch (3.010 meters) diameter, two-bladed, Hamilton Standard variable-pitch, constant-speed propellers. The Wasp S3H1 is 4 feet, 3.60 inches (1.311 meters) in diameter and 3 feet, 7.01 inches (1.093 meters) long. It weighed 865 pounds (392 kilograms).
