22 November 1933:
The K-7 Disaster
On Wednesday, November 22, the Russian aircraft K-7, claimed to be the largest landplane in the world, crashed near Kharkhoff, 420 miles south-west of Moscow. Fourteen lives were lost. It is reported that M.K.A. Kalinin, the designer and director of the Kharkhoff aeroplane works, and Snegeriff, one of the best-known pilots in Russia, are among the dead. It seems that sabotage is suspected by the authorities, for the O.G.P.U. (Soviet secret police) is represented on the commission of experts investigating the disaster. Twenty trial flights had been successfully made before the crash.
The design and construction of the K-7 took five years. She had a span of 208 ft., weighed about 20 tons and accommodated 120 passengers. She was considered a big stride forward in the approach to the “all-wing” aircraft, and most of the accommodation and equipment was in the wing. A few days before the accident the existence of the K-7 was revealed to the general public by “Pravda.” It was declared that the aircraft represented a “victory of the utmost political importance,” as she was constructed entirely of Soviet steel from the mills at Duiepropetrovsk. Hitherto Russia had [imported] materials for her aircraft.
—The Aircraft Engineer, Supplement to FLIGHT, 30 November 1933, at Page 1201.
The K-7 was designed by Konstantin Alekseevich Kalinin and built over a two-year period at the Kharkov State Aircraft Manufacturing Company factory at Kharkov, Ukraine. It was intended as either a heavy bomber in military service or as a civil transport. The K-7 was the largest airplane built up to that time.

The K-7 was an effort to perfect a “wing only” aircraft. The tail surfaces were supported by tail booms. It was operated by a crew of 11 and could carry up to 120 passengers in compartments inside the wings. The K-7 was 28.00 meters (91 feet, 10.4 inches) long with a wingspan of 53.00 meters (173 feet, 10.6 inches). The extremely large wing had an area of 254.00 meters².
As originally built the airplane was powered by six 2,896.1-cubic-inch-displacement (47.459 liter) liquid-cooled, supercharged, Mikulin AM-34 single overhead cam (SOHC) 60° V-12 engines mounted in nacelles on the leading edge of the wing. The engines were rated at 750 horsepower, each, and drove two-bladed propellers. When it was determined that power was insufficient, a seventh and then an eighth engine were added to the trailing edge in pusher configuration.
The K-7 had an empty weight of 21,000 kilograms and maximum weight of 40,000 kilograms. It’s cruise speed was 204 kilometers per hour (127 miles per hour) and the maximum speed was 234 kilometers per hour (145 miles per hour). The service ceiling was 5,500 meters (18,045 feet) and the range was 1,000 kilometers (621 miles).
In military configuration, the K-7 would be armed with 20 mm cannon and 7.62 mm machineguns. A bomb load of up to 16,000 kilograms (35,274 pounds) would be carried.

The Kalinin K-7 made only 7 test flights before it crashed. 15 of the 20 persons aboard were killed. Kalinin was not among the dead, as had been report by Flight in the article above. One of the two tail booms failed. Some suggested that sabotage was involved. A government commission determined that the structure of the tailbooms was sufficiently strong, but that oscillations induced by aerodynamic flutter led to the failure.
During World War I, Konstantin Kalinin was awarded the Order of Sv.Stanislav. He had been given the Order of the Red Banner of Labor in 1935. However, during the Stalin purges, on 23 October 1938, he was executed as an enemy of the state.

22 November 1913: Captain Charles Alexander Holcombe Longcroft, Welsh Regiment, British Army, attached to No. 2 Squadron, Royal Flying Corps, as a flight commander, flies a Royal Aircraft Factory B.E.2.a from Montrose, Scotland, non-stop to Farnborough, Hampshire, England. The distance covered was approximately 630 miles (1,014 kilometers).¹
Captain Longcroft, accompanied by Colonel Frederick Hugh Sykes, Commandant of the Military Wing, departed Montrose Aerodrome at 8:55 a.m., flying B.E.2.a number 218. He passed York at 11:55 a.m., then continued on to Portsmouth, and next to Farnborough, where he landed at 4:10 p.m. The total duration of the flight was 7 hours, 15 minutes, at an average speed of approximately 86.9 miles per hour (139.9 kilometers per hour).
At the time, British newspapers speculated as to whether Captain Longcroft had established a new world record (or at least, a British national record), but the Fédération Aéronautique Internationale does not recognize any records attributed to Longcroft. On 13 October 1913, Auguste Seguin of France had established an FAI world record for distance of 1021,20 kilometers (634.54 statute miles) at Korobcheevo, Russia.²
For this flight, Captain Longcroft was awarded the first Britannia Trophy of the Royal Aero Club of Great Britain.

Number 2 Squadron is the most senior of all Royal Air Force squadrons, having been founded at Farnborough, Hampshire, England, 13 May 1912. At the time the squadron was also known as No. II (Army Co-operation) Squadron.
Montrose Aerodrome, now known as RAF Montrose, was the first of twelve planned stations for the Royal Flying Corps. It was originally located at Upper Dysart Farm in Forfarshire, on the eastern shoreline of Scotland.
Captain Longcroft’s Bristol & Colonial Aeroplane Company B.E.2.a, number 218. (Montrose Air Station Heritage Cenre)
Captain Longcroft’s B.E.2.a., number 218, was built by British & Colonial Aeroplane Company (later, Bristol) at Filton, South Goucestershire, under order number A1147. It was delivered to the R.F.C. on 2 November 2013.
The B.E.2.a was slightly modified with the addition of a windscreen and a fuel tank with a capacity of 54 Imperial gallons (245 liters), “and special oiling arrangements.”
The Royal Aircraft Factory B.E.2.a (which stands for Blériot Experimental, meaning that it was a tractor-type airplane, which had been developed by Louis Blériot) was designed by Geoffrey de Havilland. It was a two-place, single-engine, two-bay biplane which was used as a trainer, reconnaissance aircraft, artillery spotter or bomber. An observer occupied the forward cockpit and the pilot was aft.
The fuselage was constructed of a wooden framework, cross-braced with wires. The wings had wood spars and ribs. The airframe was covered in doped fabric. The B.E.2.a used wing-warping for roll control.This would be changed to ailerons for the B.E.2.b.
The wings of the 2.a and 2.b were straight with no dihedral. Both upper and lower wings had the same span and chord, and were not staggered. (The B.E.2.c added both dihedral and stagger.) The lower wing spars were connected through the fuselage with steel tubing. The landing gear had both wheels and tires, but also wood-covered steel tube skids extending forward to protect the propeller from contacting the ground.
The B.E.2.a–2.b was 29 feet, 6½ inches (9.004 meters) long with a wingspan of 38 feet, 7½ inches (11.773 meters). The wings’ chord was 6 feet, 4 inches (1.930 meters). It had an empty weight of 1,274 pounds (578 kilograms) and gross weight of 1,600 pounds (726 kilograms).
The B.E.2, B.E.2.a and B.E.2.b were powered by an air-cooled, normally-aspirated 6.949 liter (424.036 cubic inch) Renault Type WB side-valve 90° V-8 engine with two valves per cylinder and a compression ratio of 4.12:1. The WB was rated at 70 horsepower at 1,750 r.p.m. The engine drove a four-bladed, fixed-pitch wooden propeller at one-half crankshaft speed. The Renault WB was 3 feet, 9.5 inches (1.556 meters) long, 2 feet, 8.8 inches (0.833 meters) high and 2 feet, 5.8 inches (0.757 meters) wide. It weighed 396 pounds (180 kilograms).
The airplane had a maximum speed of 70 miles per hour (113 kilometers per hour) at Sea Level and 65 miles per hour (105 kilometers per hour) at 6,500 feet (1,981 meters). It could climb to 3,000 feet (914 meters) in 9 minutes and to 7,000 feet (2,134 meters) in 35 minutes. The service ceiling was 10,000 feet (3,048 meters). Maximum endurance was 3 hours.
Although designed by the Royal Aircraft Factory, Farnborough, only 6 B.E.2s were built there. The remainder were built by Armstong Whitworth, British and Colonial Airplane Co., Coventry Ordnance Works, Handley Page, Hewlett and Blondeau, and Vickers.
Air Vice-Marshal Sir Charles Alexander Holcombe Longcroft, C.M.G., D.S.O., A.F.C., Royal Air Force,1930. (Walter Stoneman/National Portrait Gallery NPG x186018)
Air Vice-Marshal Sir Charles Alexander Holcombe Longcroft, K.C.B., C.M.G., D.S.O., A.F.C., Royal Air Force, was born Llanarth, Cardiganshire, Wales, 13 May 1883. He was the third of four children of Charles Edward Longcroft and Catherine Alicia Holcombe Longcroft. Charles was educated at Charterhouse, a private boarding school (for some incomprehensible reason, known in England as a “public school”) in Goldalming, Surrey, England. He then attended the Royal Military Academy Sandhurst.
C.A.H. Longcroft was commissioned as a second lieutenant in the Welsh Regiment of the British Army, 2 May 1903. From 1904 to 1906, he served in India. Returning to the United Kingdom, he was promoted to the rank of lieutenant, 13 December 1906. He then deployed to South Africa until 1909.
On 5 March 1912, Lieutenant Longcroft was issued an aviator’s certificate (H192) by the Royal Aero Club of the United Kingdom.
After volunteering, on 10 April 1912 Lieutenant Longcroft was assigned to the Air Battalion, Royal Engineers. The unit operated lighter-than-air craft. The following month, 13 May 1912, he was “seconded” (temporarily transferred for duties outside of his normal unit) to the newly established Royal Flying Corps. On 1 July 1912, Lieutenant Longcroft was appointed a Flying Officer, R.F.C. On 20 November 1912, he was assigned as a flight commander, No. 2 Squadron, at Farnborough and Montrose. On that same day, he was promoted to the temporary rank of captain. That rank became permanent 13 August 1913.
Captain Longcroft was promoted to the temporary rank of major, 1 May 1914, and assigned as the commanding officer No. 1 Squadron at Farnborough, which, after the start of World War I, served on the Western Front. His new rank became permanent two months later (22 June). On 19 October 1914, Longcroft was Mentioned in Dispatches.
Major Longcroft became the commanding officer of No. 4 Squadron 29 January 1915. On 18 August 1915 he was promoted to the temporary rank of lieutenant-colonel. He was reassigned to command the Training Wing.
The Imperial House of Romanov (the reigning house of Imperial Russia) awarded Major Longcroft the Order of St. Staninslas (Орденъ Св. Станислава), 3rd Class with Swords, 25 August 1915.
Brigadier-General Charles A. H. Longcroft, Royal Flying Corps, ca. 1917 (Wikipedia)
On 28 August 1916, Colonel Longcourt was promoted to the temporary rank of brigadier-general. He was placed in command of 2nd (Corps) Wing, R.F.C. (His permanent rank of lieutenant-colonel was effective 1 January 1917.) Next, on 18 October 1917, Longcroft was promoted to temporary major-general. He was next assigned as General Officer Commanding, Training Division.
France appointed him an Officier de la Ordre national de la Légion d’honneur in 1917.
On 1 April 1918, the Royal Flying Corps and Royal Naval Air Service were combined to form the Royal Air Force (R.A.F.). Major-General Longcroft was transferred from the British Army to the R.A.F. and attached to III Brigade. While retaining that temporary rank, his permanent rank of lieutenant-colonel was confirmed and he was immediately promoted to the permanent rank of colonel. On 29 April, he was advanced once again to the temporary rank of brigadier-general, and assigned as General Officer Commanding, III Brigade.
In the New Year’s Honours List, 1 January 1918, Brigadier-General Longcroft was awarded the Distinguished Service Order (D.S.O.) for service under fire.
For his service during World War I, Brigadier-General Longcroft was awarded the Distinguished Service Order; the Air Force Cross; the 1914 Star with Clasp; the British War Medal, and the Victory Medal. He was also appointed a Companion of the Most Distinguished Order of St. Michael and St. George (C.M.G.) by King George V.
On 1 May 1919, Temporary Brigadier-General Longcroft was promoted to the rank of acting brigadier-general.
The new R.A.F. changed to a new system of officer ranks. On 1 August 1919, Longcroft resigned his commission in the Welsh Brigade to accept a commission in the R.A.F. Acting Brigadier-General Longcroft became Group Captain Longcroft. Four days later, 5 August, he was promoted to Air Commodore.

Air Commodore Longroft became the first commandant of the newly established R.A.F. College at Cranwell. The first cadets arrived 5 February 1920. His command consisted of 56 officers, 516 airmen, 200 cadets, 1 headmaster and 8 schoolmasters.
Air Commodore Longcroft married Mrs. William Duncan Hepburn (née Marjory McKerrell-Brown) at St. Paul’s Church, Portman Square, London, 27 April 1921. The ceremony was officiated by Squadron Leader the Reverend Bernard William Keymer, O.B.E., R.A.F. Mrs. Hepburn was the widow of Captain W. D. Hepburn, Seaforth Highlanders, British Army. The Longcrofts would have a son, Charles McKerrell Longcroft, born in 1926. (Squadron Leader Keymer was one of the first chaplains at RAF Cranwell, and is credited with creating the school’s motto, Superna Petimus—”We seek things that are above.”)
King George V appointed Air Commodore Charles Alexander Holcombe Longcroft, C.M.G., D.S.O., A.F.C., Royal Air Force, to be an Ordinary Member of the Military Division of the Third Class, of the Most Honourable Order of the Bath (C.B.), 2 June 1923.³
On 9 October 1923, Air-Commodore Longcroft was placed on the Half-Pay List. Shortly after, 10 December, he was appointed Director of Personal Services.

“The Raid, Blue Boy Element” by Michael Nikiporenko. In this painting, a USAF/Sikorsky HH-3E Jolly Green Giant helicopter, 65-12785, from 37th Aerospace Rescue and Recovery Squadron, call sign BANANA 01, has intentionally crash-landed inside the prison compound at 0219 to insert the BLUE BOY element of Green Berets. (Son Tay Raiders Association)
21 November 1970: Operation Kingpin was a mission to rescue 61 American prisoners of war at the Sơn Tây Prison Camp, 23 miles (37 kilometers) west of Hanoi, North Vietnam. There were over 12,000 North Vietnamese soldiers stationed within five miles of the prison. The ultra-secret mission was carried out by 56 U.S. Army Special Forces soldiers and 98 airmen aboard 28 aircraft.
Months of intelligence gathering, mission planning and meticulous training preceded the mission. Personnel were selected from more than 500 volunteers. Training was conducted at Duke Field, an auxiliary field at Eglin Air Force Base, Florida. A full-size replica of the prison was constructed and live-fire training was conducted. Aircraft formations flew day and night, following the precise courses and distances that would be flown during the actual mission.
Originally planned for October, the mission had to be pushed back to November.

Two Lockheed C-130E(I) Combat Talons (a special operations variant of the four-engine Hercules transport), call signs CHERRY 01 and CHERRY 02, each led a formation of aircraft for the raid. The assault group, consisting of a Sikorsky HH-3E Jolly Green Giant, 65-12785, (BANANA 01) and five Sikorsky HH-53B/C Super Jolly Green Giant helicopters (APPLE 01–05) carried the Special Forces team. The second formation was a strike group of five Douglas A-1E Skyraiders (PEACH 01–05) for close air support. The Combat Talons provided navigation and communications for their groups and illumination over the prison.

Because there was insufficient room to land a helicopter within the prison, it was planned to have BANANA 01, flown by Major Herbert D. Kalen and Lieutenant Colonel Herbert R. Zehnder, and carrying a 14-man assault team, BLUEBOY, crash-land inside the perimeter. The Special Forces soldiers were tasked to locate and protect the prisoners and to kill any guards that might interfere. The larger helicopters first fired on the guard towers with their miniguns and then landed their soldiers outside the prison. The A-1 Skyraiders bombed and strafed nearby foot and vehicle bridges to stop reinforcements from making their way to the prison.
Assault Element Blueboy
Once inside the prison, it was quickly discovered that there were no American POWs there. The assault forces then withdrew. The total time from the beginning to the end of the assault was just 26 minutes. One American soldier suffered a gunshot wound to the leg. The crew chief of BANANA 01 broke an ankle when it was hit by a falling fire extinguisher during the crash landing. As expected, BANANA 01 was written off. Between 100–200 North Vietnamese soldiers were killed.

During the withdrawal from the area, North Vietnam fired more than 36 surface-to-air missiles at the aircraft. None were hit, though one Republic F-105G Wild Weasel, 62-4436, call sign FIREBIRD 05, was damaged by a near miss. This aircraft ran out of fuel just short of its tanker rendezvous and the crew bailed out over Laos. They were rescued by Super Jolly Green Giants APPLE 04 and APPLE 05, after they had been refueled by an HC-130P Combat Shadow, LIME 02.
Although meticulously planned and carried out, the mission failed because the POWs had been moved to another prison camp, closer to Hanoi (“Camp Faith”). Three days after the raid on Sơn Tây, they were again moved, this time to the infamous Hanoi Hilton.

Britton and MAJ Alfred C. Montream, it carried the command element for the raid. Built at Stratford, Connecticut, as a HH-53C Super Jolly Green Giant, it was continuously upgraded over its service life, to MH-53E, MH-53J and finally MH-53M. It flew its last mission 28 March 2008 in Iraq. After 38 years of continuous front line service, Three Five Seven was retired to the National Museum of the United States Air Force. (U.S. Air Force)

21 November 1947: Grumman Aircraft Engineering Corporation engineering test pilot Corwin Henry (“Corky”) Meyer took off from the company’s airfield at Bethpage, Long Island, New York, in the first prototype XF9F-2 Panther, Bu. No. 122475. After the preliminary flight evaluation, Meyer landed the new jet fighter on a longer runway at Idlewild Airport. The Bethpage runway was only 5,000 feet (1,524 meters) long. As the first jet aircraft built by Grumman, it wasn’t known if the XF9F-2 could land on that short a runway.
Air & Space/Smithsonian magazine quoted Meyer as saying that the weather was “the foulest of any first flight in my experience.” He described the prototype’s handling qualities: “It handled like a J-3 Cub.” In an article for Flight Journal, Corky Meyer wrote: “I conducted a very satisfactory first flight of the 5,000-pound-thrust Rolls-Royce Nene-powered fighter on November 21, 1947.”
The XF9F-2 Panther was the first jet-powered aircraft to be built by Grumman, a major supplier of aircraft for the United States Navy. It was a single-seat, single-engine, day fighter, designed for operation on the U.S. Navy’s aircraft carriers. It was developed from a proposed four-engine XF9F-1 night fighter. Grumman planned to use the Rolls-Royce RB.41 Nene centrifugal-flow turbojet engine. With 5,000 pounds rated thrust at 12,400 r.p.m., the Nene was more powerful (and more reliable) than any engine manufactured by an American company.

The Nene was licensed for production in the United States to the Taylor Turbine Corporation as the J42-TT-2. No J42s were ready, so Taylor supplied Grumman with imported Rolls-Royce engines. The Navy had concerns about Taylor’s capability to produce engine in sufficient quantities and arranged for the J42 license to be sold to Pratt & Whitney.

The Panther was placed into production as the F9F-2. The F9F-2 was 37 feet, 5-3/8 inches (11.414 meters) long with a wingspan of 38 feet, 5⅜ inches (11.719 meters) long, with a wingspan of 38 feet, 0 inches (11.528 meters)—not including wing tanks. Its overall height was 11 feet, 4 inches (3.454 meters). The wings could be hydraulically folded to reduce the span for storage aboard ship. The Panther weighed 9,303 pounds (4,220 kilograms) empty, and had a gross weight of 19,494 pounds (8,842 kilograms.

The F9F-2 was powered by a Pratt & Whitney JT6 (J42-P-8) turbojet engine which produced 5,000 pounds of thrust (22.241 kilonewtons) at Sea Level, and 5,750 pounds (25.577 kilonewtons) with afterburner. The J42 was a license-built version of the Rolls-Royce Nene. The engine used a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. The J42-P-8 weighed 1,715 pounds (778 kilograms).
The Panther had a maximum speed of 575 miles per hour (925 kilometers per hour) at Sea Level. Its service ceiling was 44,600 feet (13,594 meters), and the range was 1,353 miles (2,177 kilometers).
The Panther was armed with four M3 20 mm autocannon placed in the nose with 760 rounds of ammunition. It could carry up to 3,000 pounds (1,361 kilograms) of bombs or eight 5-inch (12.7 centimeters) rockets on four hardpoints under each wing.

It was a very successful air-to-air and air-to-ground fighter during the Korean War. On 18 November 1952, Lieutenant Elmer Royce Williams, USN, flying an F9F-5 Panther, Bu. No. 125459, of VF-781 aboard the aircraft carrier USS Oriskany (CVA-34), shot down four of seven Soviet Air Force MiG 15 fighters which had launched from Vladivostok toward Task Force 77. His Panther sustained significant damage from enemy cannon shells. Though he safely returned to his carrier, the fighter, Number 106, was so badly damaged that it was pushed over the side. Lieutenant Williams was awarded the Silver Star for this action. No other pilot has ever shot down four MiG fighters during a single combat action.

The F9F Panther was flown during the Korean War by such famed naval aviators as Ted Williams, and future astronauts John Glenn and Neil Armstrong.
Grumman built 1,358 F9F-2,-3,-4 and -5 Panthers and another 1,392 swept wing F9F-6, -7 and -8 Cougars. Panthers remained in service with the United States Navy until 1958, and Cougars until 1974.
The combat survivability of Grumman’s fighters earned the factory the nickname of “The Grumman Iron Works.” In this photograph, future NASA astronaut Major John H. Glenn, U.S. Marine Corps, the first American to orbit the Earth, examines some of the 714 holes in his F9F Panther. (U.S. Navy)
Corwin Henry (“Corky”) Meyer ¹ was born 14 April 1920 at Springfield, Illinois. He was the second of three children of Dr. John Gerhard Meyer, a physician and surgeon, and Betsy Arenia Corwin Meyer.

At the age of 17 years, Corky Meyer learned to fly in the Civilian Pilot Training Program. (This was a federal government-funded program which provided 72 hours of ground school and 35–50 hours of flight training, intended to increase the number of pilots available for civilian aviation.)
Meyer attended Springfield High School, in Springfield. He was a member of the Senior Boys’ Council and the National Honor Society. Meyer graduated from high school in May 1938, then entered the University of Illinois. He studied at the at the Massachusetts Institute of Technology (M.I.T.), Cambridge, Massachusetts, 1942–43.
Meyer was a pilot trainee for Pan American Airways before being employed as an engineering test pilot at the Grumman Aircraft Engineering Corporation at Bethpage, New York.

Meyer’s first project was testing newly-built TBF Avenger torpedo bombers. Later he was was a project test pilot for the F6F Hellcat, F8F Bearcat and F7F Tigercat. (Robert Leicester Hall made the first flights of these airplanes, but Corky Meyer was involved in flight testing of each of them early on.)

Corwin H. Meyer married Miss Dorothy Marjorie Fyfield, 7 April 1945, at Huntington, New York. They would have a daughter, Sandra Louise Meyer, born in 1950, and two sons, John Fyfield Meyer and Peter Meyer.

On 19 May 1952, Corky Meyer took the prototype variable-wing-sweep XF10F-1 Jaguar for its first flight at Edwards Air Force Base, California.

From 1952 to 1954, Meyer was head of Grumman’s flight operations at Edwards Air Force Base in California. In 1954, he became the first civilian airplane pilot to qualify for flight operations aboard U.S. Navy aircraft carriers, when he flew an F9F-6 Cougar to USS Lake Champlain (CVA-39). ²
Corky Meyer made the first flight of the XF9F-9 prototype, Bu. No. 138604, on 30 July 1954, and was able to approach mach 1 in level flight. The XF9F-9 was a completely redesigned F9F Cougar, which incorporated the “wasp-waist” in its area-ruled fuselage. The following year, this type would be redesignated the F11F Tiger.
In 1967, Meyer was appointed vice president of Grumman, and in 1968, he was elected to the board of directors of the Grumman Aerospace Corporation. He became the senior vice president of Grumman Aerospace in 1972. In 1974, Meyer became President of Grumman American Aviation Corp., Savannah, Georgia, a subsidiary which produced light civil airplanes, the Grumman AgCat, and the Gulfstream line of executive jets. Corwin Meyer retired from Grumman in 1978. He later served as chief executive officer of the Enstrom Helicopter Corporation and the Falcon Jet Corporation.

Meyer was an early member of the Society of Experimental Test Pilots. In 1971, he was awarded SETP’s James H Doolittle Award for excellence in technical management or engineering achievement in aerospace technology. In 1999 the National Aeronautic Association selected him for its Elder Statesman Award.
Meyer was the author of Corky Meyer’s Flight Journal, an autobiography published in 2005, by Specialty Press, North Branch, Minnesota.
Corwin Henry Meyer died in Naples, Florida, 1 June 2011, at the age of 91 years.
¹ Lutheran Church birth and baptismal records give Meyer’s name as “Henry Corwin Meyer.”
² On 3 April 1991, TDiA’s author became the only civilian helicopter pilot (at that time, and who was not a former military pilot) to qualify to fly from U.S. Navy warships at sea. The Deck Landing Qualification (DLQ) flights were evaluated by instructors from Helicopter Antisubmarine (Light) Squadron (HSL-31) aboard USS Kincaide (DDG-965), a Spruance-class guided missile destroyer.

21 November 1783: At approximately 2:00 p.m., Jean-François Pilâtre de Rozier and François Laurent le Vieux d’Arlandes (Monsieur le Marquis d’Arlandes) departed Château de la Muette, the home of Louis XVI and Marie-Antoinette near the Bois de Boulogne in the western outskirts of Paris, aboard a hot air balloon which had been designed and built by the brothers Joseph-Michel Montgolfier and Jacques-Étienne Montgolfier.
De Rozier had made several tethered ascents previously, learning to control the balloon. On this, the first manned, untethered ascent, de Rozier and Marquis d’Arlandes rose to an altitude of approximately 3,000 feet (910 meters) and drifted to the southwest. After about 25 minutes, they descended to land between two windmills outside the city, at Butte-aux-Cailles. They had traveled about five miles (nine kilometers). They could have flown farther, but the embers from the fire were beginning to scorch the balloon.
The Montgolfier brothers were the sons of a paper maker. They combined with Jean-Baptiste Réveillon, a wallpaper manufacturer, to construct their balloon envelopes of taffeta (a woven silk fabric) coated by an alum/varnish mixture.
The balloon flown by de Rozier and the Marquis d’Arlandes had an approximate volume of 60,000 cubic feet (1,699 cubic meters). It was approximately 75 feet (22.86 meters) tall with a diameter of 50 feet (15.24 meters). The air within the balloon was heated by burning coals. This resulted in a pressure differential: the heated air was less dense than the ambient air. This caused the balloon to rise.

Jean-François Pilâtre de Rozier was killed 15 June 1785, while attempting to cross the English Channel in a hydrogen balloon along with Pierre Romain. Adverse winds blew him back onshore, but for unknown reasons, the balloon collapsed and fell approximately 1,500 feet (457 meters) to the ground near Wimereux, Pas-de-Calais.
François Laurent le Vieux d’Arlandes died in 1806, possibly committing suicide.
