Prototype Learjet 23, N801L, first flight, 7 October 1963. (Lear Jet Corporation)
7 October 1963: The first of two Learjet 23 prototypes, N801L, makes its first flight at Wichita, Kansas, with test pilots Henry Grady (“Hank”) Beaird, Jr., and Robert S. Hagan. A light twin-engine business jet, the Learjet 23 is considered a “first” because it was designed from the start as a civil aircraft.
The Learjet 23 is operated by two pilots and can carry six passengers. It is 43 feet, 3 inches (13.183 meters) long with a wingspan of 35 feet, 7 inches (10.846 meters) and overall height of 12 feet, 7 inches (3.835 meters). It has an empty weight of 6,150 pounds (2,790 kilograms) and maximum takeoff weight of 12,499 pounds (5,670 kilograms).
A characteristic of all Learjets is the 13° sweep of their wings’ leading edges, and the straight trailing edge.
Learjet 23 N802L was the second prototype. This airplane is in the collection of the Smithsonian Instititution National Air and Space Museum. (NASM 9A11735)
The airplane was powered by two General Electric CJ610-4 turbojet engines. The CJ610 is a single-shaft axial-flow turbojet with an 8-stage compressor and 2-stage turbine. The CJ610-4 has a maximum continuous power rating of 2,700 pounds (12.010 kilonewtons) at 16,500 r.p.m. at Sea Level, and 2,850 pounds of thrust (12.677 kilonewtons) at 16,700 r.p.m., for takeoff (5 minute limit). The engine is 3 feet, 4.50 inches (1.029 meters) long, 1 foot, 5.56 inches (0.446 meters) in diameter, and weighs 403 pounds (183 kilograms).
The Learjet 23 has a cruise speed of 518 miles per hour (834 kilometers per hour) at 40,000 feet (12,192 meters) and a maximum speed of 561 miles per hour (903 kilometers per hour), 0.82 Mach, at 24,000 feet (7,315 meters). The service ceiling is 45,000 feet (13,716 meters) and its maximum range is 1,830 miles (2,945 kilometers).
Lear Jet Corporation built approximately 100 Learjet 23s.
The first prototype was damaged beyond economical repair while simulating an engine failure on takeoff during flight testing, 4 June 1964. The accident was attributed to pilot error. N801L had accumulated just 194 flight hours.
7 October 1959: An E-2A space probe, Luna 3, was launched by the Union of Soviet Socialist Republics at 00:43:39.7 UTC, 4 October 1959, from the Tyuratam Launch Complex (now known as the Baikonur Cosmodrome). The launch vehicle was a 3-stage 8K72 rocket, a variant of the R7 Semyorka two-stage intercontinental ballistic missile. Luna 3 was approximately cylindrical, 130 centimeters (4 feet, 3.2 inches) long, with a diameter of 120 centimeters (3 feet, 11.2 inches). It weighed 278.5 kilograms (614 pounds).
At 1416 UTC, 6 October, the probe made its closest approach as it passed over the lunar south pole at 6,200 kilometers (3,852 miles) and continued around the far side of The Moon in an highly eccentric orbit. For 40 minutes, between 0330 and 0410 UTC, 7 October, cameras aboard Luna 3 took a series of images of the surface. These photographs, taken at a distance of 63,500 to 66,700 kilometers (39,457 to 41,445 miles), were the first photos ever taken of The Moon’s far side. Exposed film from the cameras was processed on board, then transmitted to Earth as television signals.
The orbit of Luna 3 was highly eccentric with a 15 day period. It came as close as 40,638 kilometers and as far as 460,755 kilometers (25,251 miles to 286,300 miles) from The Moon. Contact was lost 22 October 1959. It is believed to have reentered the Earth’s atmosphere after April 1960.

Albert Plesman, founder of Koninklijke Luchtvaart Maatschappij N.V. (KLM)
7 October 1919: Koninklijke Luchtvaart Maatschappij N.V., operating under the name KLM Royal Dutch Airlines, was founded on 7 October 1919 by Albert Plesman, making it the oldest carrier in the world still operating under its original name, though the company stopped operating during the Second World War—apart from the operations in the Dutch Antilles in the Caribbean.
KLM flew its first scheduled passenger service with this Airco DH.16, G-EALU, from Croydon to Amsterdam, 17 May 1920. (Unattributed)
The first KLM flight was on 17 May 1920, from Croydon Airport, London, to Amsterdam, The Netherlands, carrying two British journalists and a number of newspapers. It was flown by an Airco DH.16, registration G-EALU, piloted by Henry (“Jerry”) Shaw.¹ This airplane, named Arras, was leased from Aircraft Transport and Travel Limited, a British company. Shaw was that company’s chief pilot.
In 1920 KLM carried 440 passengers and 22 tons of freight. In 1921 KLM started scheduled services.
As of 31 December 2023, KLM’s fleet included 238 aircraft. The airline had approximately 35,145 employees.

A flight of two U.S. Army OH-58D Kiowa Warrior scout helicopters. (Bell Helicopter)
6 October 1983: First flight of the Bell Helicopter Company Model 406/OH-58D Kiowa reconnaissance helicopter. Developed from the earlier Model 206/OH-58A and OH-58C Kiowa, the D model features a four-blade composite main rotor, an upgraded engine and transmission, and improved avionics. The most visible features are the spherical mast-mounted sighting system above the main rotor and much larger engine/transmission cowling, or “dog house.”
The helicopter was designed with very low level, “nap-of-the-Earth,” (NOE) flight, using terrain and trees for cover. The four-bladed rotor provides more lift and increased responsiveness over the two-bladed semi-rigid rotor of the OH-58A and C.
The mast-mounted sight allows the helicopter to hover behind terrain or trees with just the sight exposed. The sight contains television, thermal imaging and laser range-finding and target designation equipment.

Operated by two pilots, the Bell OH-58D Kiowa is 42 feet, 2 inches (12.852 meters) long, with rotors turning. The four-bladed composite main rotor has a diameter of 35 feet (10.668 meters). As is customary with American-designed helicopters, the main rotor turn counter-clockwise as seen from above. (The advancing blade is on the right side of the aircraft.) The two-blade semi-rigid tail rotor is mounted on the left side of the tail boom and turns clockwise when seen from the left. (The advancing blade is below the tail boom.) The overall height of the OH-58D is 12 feet, 10–5/8 inches (3.928 meters). Empty weight of the helicopter is about 3,500 pounds (1,588 kilograms), depending on installed equipment. This is approximately 15% greater than the maximum gross weight of the OH-58A. The OH-58D has a maximum gross weight of 5,500 pounds (2,495 kilograms).
Power for the Kiowa is supplied by a Rolls-Royce T703-AD-700A (Allison 250-C30R3) turboshaft engine which produces 750 shaft horsepower. The main transmission is limited to transient input of 637 shaft horsepower.
The helicopter can be armed with a fixed, remotely-fired, M3P .50-caliber (12.7 mm) machine gun, a pod carrying seven 2.75-inch (70 mm) rockets, or two AGM-114 Hellfire antitank guided missiles.
The OH-58D has a cruise speed of 95 knots (109 miles per hour/176 kilometers per hour) when armed. Its range is 140 nautical miles (161 miles/259 kilometers). The hover ceiling in ground effect (HOGE) at +15 °C. is 7,500 feet MSL (2,286 meters).

The first prototype Mikoyan MiG 29A, 9-01, (“01 Blue”) on display at the Central Air Force Museum, Monino. (Detail from image by AVIA BavARia/Wikipedia)Alexander Vasilievich Fedotov
6 October 1977: The first of eleven prototypes of the Mikoyan MiG 29A fighter, 9-01, made its first flight at Ramenskoye Airfield with Chief Test Pilot Alexander Vasilievich Fedotov, Hero of the Soviet Union, in the cockpit.
Fedotov had been a test pilot at A.I. Mikoyan EDB since 1958 and set eighteen speed and altitude world records flying high performance aircraft. He was killed while testing the MiG 31 in 1984.
The MiG 29A is a fourth generation, single-seat, twin-engine, Mach 2+ air superiority fighter built by the Mikoyan Design Bureau. It entered service with the Soviet Union in 1983 and has been widely exported to many other nations. The MiG 29A is 13.37 meters (57 feet) long and has a wing span of 11.4 meters (37 feet, 3 inches). Its empty weight is 11,000 kilograms (24,250 pounds) and the maximum takeoff weight (MTOW) is 20,000 kilograms (44,100 pounds). The fighter is powered by two Klimov RD-33 turbofan engines which produce 11,240 pounds of thrust, or 18,277 pounds of thrust with afterburner. It has a maximum speed of Mach 2.25 (1,490 miles per hour/2,400 kilometers per hour) and a service ceiling of 59,100 feet (18,013 meters). Maximum range with internal fuel is 1,430 kilometers (888 miles).
Armament consists of one Gryazev-Shipunov GSh-301 30mm autocannon with 150 rounds of ammunition and a combination of air-to-air missiles, rockets or bombs carried on underwing pylons or fuselage hard points.
Alexander Vasilievich Fedotov born 23 June 1932 at Stalingrad, Russia (renamed Volgograd in 1961). He graduated from the Air Force Special School at Stalingrad, and in 1950, entered the Soviet Army. Fedotov attended the Armavir Military Aviation School of Pilots at Amravir, Krasnodar Krai, Russia, graduating in 1952, and then became a flight instructor. In 1958 he attended the Ministry of Indutrial Aviation Test Pilot School at Zhukovsky. He was a test pilot for the Mikoyan Experimental Design Bureau from 1958 to 1984. In 1983, Alexander Fedotov was promoted to the rank of Major General in the Soviet Air Force.
On 22 July 1966, Fedotov was honored as a Hero of the Soviet Union. He was named an Honored Test Pilot of the Soviet Union, 21 February 1969. He was qualified as a Military Pilot 1st Class. Fedotov was twice awarded the order of Lenin, and also held the Order of the Red Banner and the Order of the Red Banner of Labor.
During his career as a test pilot, Major General Fedotov had been forced to eject from an airplane three times. He had also set 15 Fédération Aéronautique Internationale world records for speed, altitude and time to altitude. One of these, FAI Record File Number 2825, in which he flew a Mikoyan E-266M to 37,650 meters (123,534 feet), 31 August 1977, remains the current record. The FAI has also honored him three times (1961, 1973 and 1977) with The De la Vaulx Medal, and in 1976 awarded him the FAI’s Gold Air Medal.
Major General Alexander Vasilyevich Fedotov and his navigator, Valerie Sergeyvich Zaytevym, were killed when the second MiG 31 prototype, number 83/2, crashed during a test flight. Neither airman was able to eject.
