Venera 9 had been launched from the Baikonur Cosmodrome aboard a Proton-K rocket, 8 June 1975. The space probe weighed 4,936 kilograms (10,882 pounds).
Once in orbit around Venus, the spacecraft separated into the orbiter and lander. As the lander descended to the surface, data was collected about the planet’s atmosphere. A 40-kilometer (25-mile) deep layer of clouds was studied. The cloud bases were about 35–40 kilometers (22–25 miles) above the surface. The clouds contained hydrochloric and hydrofluoric acid, bromine and iodine.
At the planet’s surface the atmospheric pressure was 90 times that of Earth’s. The temperature was measured at 485 °C. (905 °F.).

22 October 1955: At Edwards Air Force Base, in the high desert of southern California, Republic Aviation Corporation test pilot Russell M. (“Rusty”) Roth took the first of two prototype YF-105A-1-REs, serial number 54-098, for its first flight.
Though equipped with an under-powered Pratt & Whitney J57-P-25 interim engine, the new airplane was able to reach Mach 1.2 in level flight.
Aerodynamic improvements to the engine intakes and redesign of the fuselage to incorporate the drag-reducing “area rule,” along with the more powerful J75-P-5 turbojet engine allowed the production model F-105B to reach Mach 2.15.
The Thunderchief is the largest single-place, single-engine aircraft ever built. It was a Mach 2 fighter-bomber, designed for NATO defensive tactical nuclear strikes with a nuclear bomb carried in an internal bomb bay. The YF-105A was 61 feet, 0 inches (18.593 meters) long, with a wing span of 34 feet, 11 inches (10.643 meters) and overall height of 17 feet, 6 inches (5.334 meters). Its empty weight was 20,454 pounds (9,277 kilograms) and the Maximum Takeoff Weight (MTOW) was 41,500 pounds (18,824 kilograms).
The Pratt & Whitney Turbo Wasp JT3C (J57-P-25) was a two-spool axial-flow turbojet engine with a 16-stage compressor section (9 low- and 7 high-pressure stages) and a 3-stage turbine (1 high- and 2 low-pressure stages). The J57-P-25 had a Normal Power rating of 8,700 pounds of thrust (38.700 kilonewtons), and at Military Power produced 10,200 pounds of thrust (45.372 kilonewtons) (30-minute limit). The Maximum Power rating was 16,000 pounds of thrust (71.172 kilonewtons) with afterburner (5-minute limit). The J57-P-25 was 22 feet, 3.1 inches (6.784 meters) long, 3 feet, 3.8 inches (1.011 meters) in diameter, and weighed 5,120 pounds (2,322 kilograms).
The YF-105A’s wings were swept 45° at 25% chord. The angle of incidence was 0° and there was no twist. The wings had 3° 30′ anhedral. The total wing area was 385 square feet (35.8 square meters).
During testing, the prototype’s maximum speed was 770 knots (886 miles per hour (1,426 kilometers per hour) at 35,000 feet (10,668 meters)—Mach 1.34—and 676 knots (778 miles per hour/1,252 kilometers per hour) at Sea Level—Mach 1.02. The YF-105A’s service ceiling was 52,050 feet (15,865 meters). It’s combat radius was 950 nautical miles (1,093 statute miles/1,759 kilometers), and the maximum ferry range was 2,321 nautical miles (2,671 statute miles/4,298 kilometers).

The Thunderchief was armed with a General Electric T171E2 (M61) 20 mm six-barrel rotary cannon with 1,030 rounds of ammunition. 8,000 pounds (3,629 kilograms) of bombs could be carried in an internal bomb bay or on external hardpoints. A single free-fall B28IN variable-yield thermonuclear bomb could be carried in the bomb bay.
On 16 December 1955, YF-105A 54-098 made an emergency landing at Edwards AFB after one of its main landing gear assemblies was torn off when it failed to retract during a high speed flight. The pilot, Rusty Roth, was severely injured, but he survived. The prototype was shipped back to Republic for repair, but the cost was determined to be prohibitive.
Though designed for air-to-ground attack missions, F-105s are officially credited with 27.5 victories in air combat.
833 Thunderchiefs were built by Republic between 1955 and 1964. 334 of those were lost to enemy action during the Vietnam War. The F-105 remained in service with the United States Air Force until 1980, and with a few Air National Guard units until 1983.

The Caproni Ca.161bis was an experimental single-seat, single engine, two-bay biplane developed from the earlier Ca.113. It was 27 feet, ¾ inch (8.249 meters) long with a wingspan of 46 feet, 9 inches (14.249 meters) and height of 11 feet, 5¾ inches (3.500 meters). The airplane’s empty weight was 1,205 kilograms (2,657 pounds) and gross weight was 1,650 kilograms (3,638 pounds).
ub The Ca.161bis was powered by an air-cooled, supercharged, 38.673 liter (2,359.97 cubic inch) Piaggio P.XI R.C.100/2v two-row 14-cylinder radial engine which produced 700 horsepower and drove a four-bladed propeller through a 0.62:1 reduction gear. This engine was a license-built version of the French Gnome-Rhône 14K Mistral Major.

During a competition for the Coupe Deutsch de la Meurthe, Lieutenant Le Marquis Bernard Henri Marie Léonard Barny de Romanet of France’s Aéronautique Militaire flew a Nieuport-Delâge Ni-D 29V to set two Fédération Aéronautique Internationale (FAI) World Records for Speed Over a Closed Circuit of 268.63 kilometers per hour (166.92 miles per hour).¹
De Romanet’s Ni-D 29V was one of three racing variants of the highly successful single-engine, single-seat Ni-D 29C.1 biplane fighter, which was the fastest in the world at the time. The Ni-D 29V was 21 feet, 3.5 inches (6.489 meters) long, with a wing span of just 6.00 meters (19 feet, 8¼ inches), shortened from the 31 feet, 10 inch (9.703 meters) wingspan of the standard production chasseur.

The airplane was powered by a water-cooled, normally aspirated, 18.473 liter (1,127.29-cubic-inch displacement) right-hand tractor Hispano-Suiza 8Fb single overhead cam (SOHC) 90° V-8 engine, modified to increase its output to 320 horsepower. This was a direct-drive engine, and turned a two-bladed-fixed pitch propeller. The engine was 1.32 meters (4 feet, 4 inches) long, 0.89 meters (2 feet, 11 inches) wide, and 0.88 meters (2 feet, 10½ inches) high. It weighed 256 kilograms (564 pounds).
The standard airplane had a top speed of 235 kilometers per hour (146 miles per hour), a range of 580 kilometers (360 miles) and a service ceiling of 8,500 meters (27,887 feet).

Le Marquis Bernard Henri Marie Léonard Barny de Romanet was born at Saint-Maurice-de-Sathonay, Saône-et-Loire, Bourgogne, France, 28 January 1894. He was the son of Léonard Jean Michel Barny de Romanet and Marie Noémie Isabelle de Veyssière. He descended from a very old French family.
Bernard de Romanet joined the Cavalry at the age of 18 years. During World War I, he served with both cavalry and infantry regiments as a Maréchel de Logis (master sergeant) before transferring to the Aéronautique Militaire in July 1915, as a photographer and observer.
After completing flight training in 1916, de Romanet was assigned as a pilot. In early 1918, de Romanet trained as a fighter pilot. He shot down his first enemy airplane 23 May 1918, for which he was awarded the Médaille Militaire, and was promoted to Adjutant (warrant officer). De Romanet was commissioned as a Sous-Lieutenant (equivalent to a second lieutenant in the United States military) several months later. After a fourth confirmed victory he was promoted to the rank of Lieutenant (first lieutenant).
By August 1918, he was in command of Escadrille 167. He was officially credited with having shot down 18 enemy aircraft, sharing credit for 12 with other pilots. He claimed an additional 6 airplanes destroyed.
Lieutenant de Romanet was appointed Chevalier de la légion d’honneur, and was awarded the Croix de Guerre with three étoiles en vermeil (silver gilt) stars and 10 palmes.
Bernard Henri Marie Léonard Barny de Romanet was killed 23 September 1921, when the fabric covering of his Lumière-De Monge 5.1 airplane’s wings was torn away and the airplane crashed.
