28 February 1966: The primary and back up flight crews of Gemini IX flew from Houston to St. Louis where they planned to visit the McDonnell Aircraft Corporation, where the spacecraft was being built. They flew aboard two Northrop T-38A Talon supersonic trainers which NASA used for proficiency training.

The lead aircraft, NASA 901, was flown by Commander Elliot McKay See, Jr., United States Navy Reserve. See was designated as the Command Pilot for Gemini IX. Captain Charles Arthur (“Charlie”) Bassett II, U.S. Air Force, Pilot, Gemini IX, was in the rear cockpit. NASA 901 was a Northrop T-38A-50-NO Talon 63-8181 (Northrop serial number N.5528).

The second T-38, NASA 907, was flown by Lieutenant Colonel Thomas P. Stafford, U.S. Air Force, and Lieutenant Commander Eugene A. Cernan, U.S. Navy.

Weather at Lambert-St. Louis Municipal Airport was poor with low clouds and limited visibility in rain and snow. Lambert Field weather at 8:25 a.m. was: sky partially obscured, measured ceiling 800 feet (244 meters) broken, 1,500 feet (457 meters) overcast, visibility 1½ miles (2.4 kilometers) in light rain, light snow, and fog.

Elliot See flew an ILS instrument approach and broke out of the clouds properly aligned with the runaway, but was too high to make a landing. He requested a visual, circling approach. The T-38 entered a 360° turn to the southeast at approximately 500 feet (152 meters). During the circling approach, Stafford, in NASA 907, lost sight of See’s T-38 and executed a missed approach. As his airplane came around to line up for the runway, See radioed that he had the runway in sight, but, at 8:58 a.m., NASA 901 struck the top of McDonnell’s Building 101 and crashed.

The wreck immediately caught fire and both See and Bassett were killed. Sixteen people on the ground were injured.

The accident investigation board found that at approximately 3 seconds before the crash, Elliot See had apparently tried to climb away. The T-38’s angle of bank was significantly reduced and afterburner was selected.

The T-38 was the world’s first supersonic flight trainer. The Northrop T-38A Talon is a pressurized, two-place, twin-engine, jet trainer. Its fuselage is very aerodynamically clean and uses the “area-rule” (“coked”) to improve its supersonic capability. It is 46 feet, 4.5 inches (14.135 meters) long with a wingspan of 25 feet, 3 inches (7.696 meters) and overall height of 12 feet, 10.5 inches (3.924 meters). The one-piece wing has an area of 170 square feet (15.79 square meters). The leading edge is swept 32°. The airplane’s empty weight is 7,200 pounds (3,266 kilograms) and maximum takeoff weight is approximately 12,700 pounds (5,761 kilograms).

The T-38A is powered by two General Electric J85-GE-5 turbojet engines. The J85 is a single-shaft axial-flow turbojet engine with an 8-stage compressor section and 2-stage turbine. The J85-GE-5 is rated at 2,680 pounds of thrust (11.921 kilonewtons), and 3,850 pounds (17.126 kilonewtons) with afterburner. It is 108.1 inches (2.746 meters) long, 22.0 inches (0.559 meters) in diameter and weighs 584 pounds (265 kilograms)

The T-38A has a maximum speed of Mach 1.08 (822 miles per hour/1,323 kilometers per hour) at Sea Level, and Mach 1.3 (882 miles per hour/1,419 kilometers per hour) at 30,000 feet (9,144 meters). It has a rate of climb of 33,600 feet per minute (171 meters per second) and a service ceiling of 55,000 feet (16,764 meters). Its range is 1,140 miles (1,835 kilometers).

Between 1959 and 1972, 1,187 T-38s were built at Northrop’s Hawthorne, California, factory. As of 4 September 2018, 546 T-38s remained in the U.S. Air Force active inventory. The U.S. Navy has 10, and as of 30 October 2018, the Federal Aviation Administration reports 29 T-38s registered to NASA.

Société nationale des constructions aéronautiques du Sud-Est SE 3160 Alouette prototype, F-ZWVQ. (Jean Delmas)

28 February 1959: Société nationale des constructions aéronautiques du Sud-Est (SNCASE) test pilot Jean Ernest Boulet took the first prototype SE 3160 Alouette III, F-ZWVQ, for its first flight at Marignane, France.

After extensive testing, the helicopter was put into production as the Sud-Aviation SA 316A Alouette III. In 1968, the helicopter was re-engined and designated SA 316B. In 1970, the Alouette III was again re-engined and designated the Aérospatiale SA 319B

This helicopter is extremely effective at high altitudes and is widely used in the Alps, the Canadian Rockies and the Himalayas. The SA 319B is a development of the previous SA 316B. It is a single-engine, seven-place, light helicopter, operated by one or two pilots.

The helicopter’s fuselage is 10.175 meters (33 feet, 4.6 inches) long, with a main rotor diameter of 11.020 meters (36 feet, 1.9 inches). It has a height of 3.000 meters (9 feet, 10.1 inches).

The three-bladed articulated main rotor follows the French practice of turning clockwise as seen from above. (The advancing blade is on the helicopter’s left side.) Main rotor speed is 353.2 r.p.m. at 100% NR. In autorotation, it may operate in a range from 270 to 420 r.p.m. A three-bladed tail rotor is mounted on the right side of the tail boom in a pusher configuration. It turns clockwise as seen from the helicopter’s left side. (The advancing blade is below the tail boom.) The tail rotor has a diameter of 1.912 meters (6 feet, 3.228 inches). The tail rotor speed is 2,001 r.p.m.

The SA 316A was powered by a Turboméca Artouse IIIB, single shaft gas turbine engine. Single stage, axial-flow, single-stage centriugal flow compressor, annualr combustor and three stage turbine. ,  870 h.p. for takeoff 33,500 r.p.m. 182 kg.

The SA 319B is powered by a Turboméca Astazou XIV turboshaft engine, capable of producing 870 shaft horsepower, but derated to 660 shaft horsepower. This provides a power rating of 90 horsepower more than the earlier helicopter’s Artouste IIIB engine. The engine turns 33,500 r.p.m at 100% N1.

At its maximum gross weight the SA 316B Allouette III has a cruising speed of 185 kilometers per hour (100 knots, or 115 miles per hour), and a maximum speed (VNE) of 210 kilometers per hour (113 knots, 130 miles per hour), both at Sea Level. Its range is 470 kilometers (254 nautical miles, 292 statute miles), and the service ceiling is 6,000 meters (19,685 feet).

As with all helicopters, the Alouette III’s Hover Ceiling varies with its weight. At maximum gross weight, the Hover Ceiling in Ground Effect (HIGE) is 1,650 meters (5,413 feet), and out of Ground Effect (HOGE), just 100 meters (328 feet), MSL. At a reduced gross weight of 1,750 kilograms (3,858 pounds), HIGE increases to 5,550 meters (18,045 feet), and HOGE, 1,650 meters (5,413 feet). With the same weights, the helicopter’s rate of climb varies from 4.3 meters per second to 8.7 meters per second (846–1,713 feet per minute).

Jean Ernest Boulet

Jean Ernest Boulet was born 16 November 1920, in Brunoy, southeast of Paris, France. He was the son of Charles-Aimé Boulet, an electrical engineer, and Marie-Renée Berruel Boulet.

He graduated from Ecole Polytechnique in 1940 and the Ecole Nationale Supérieure de l’aéronautique In 1942. (One of his classmates was André Edouard Turcat, who would also become one of France’s greatest test pilots.)

Following his graduation, Boulet joined the Armée de l’Air (French Air Force)and was commissioned a sous-lieutenant. He took his first flight lesson in October. After the surrender of France in the Nazi invaders, Boulet’s military career slowed. He applied to l’Ecole Nationale Supérieure de l’Aéronautique in Toulouse for post-graduate aeronautical engineering. He completed a master’s degree in 1943.

During this time, Boulet joined two brothers with La Resistance savoyarde, fighting against the German invaders as well as French collaborators.

In 1943, Jean Boulet married Mlle. Josette Rouquet. They had two sons, Jean-Pierre and Olivier.

In February 1945, Sous-lieutenant Boulet was sent to the United States for training as a pilot. After basic and advanced flight training, Bouelt began training as a fighter pilot, completing the course in a Republic P-47D Thunderbolt. He was then sent back to France along with the other successful students.

On 1 February 1947 Jen Boulet joined Société nationale des constructions aéronautiques du Sud-Est (SNCASE) as an engineer and test pilot. He returned to the United States to transition to helicopters. Initially, Boulet and another SNCASE pilot were sent to Helicopter Air Transport at Camden Central Airport,  Camden, New Jersey, for transition training in the Sikorsky S-51. An over-enthusiastic instructor attempted to demonstrate the Sikorsky to Boulet, but lost control and crashed. Fortunately, neither pilot was injured. Boulet decided to go to Bell Aircraft at Niagara Falls, New York, where he trained on the Bell Model 47. He was awarded a helicopter pilot certificate by the U.S. Federal Aviation Administration, 23 February 1948.

Officier de l’Legion de Honneur

As a test pilot Boulet made the first flight in every helicopter produced by SNCASE, which would become Sud-Aviation and later, Aérospatiale (then, Eurocopter, and now, Airbus Helicopters).

While flying a SE 530 Mistral fighter, 23 January 1953, Boulet entered an unrecoverable spin and became the first French pilot to escape from an aircraft by ejection seat during an actual emergency. He was awarded the Médaille de l’Aéronautique.

Jean Boulet was appointed Chevalier de la légion d’honneur in 1956, and in 1973, promoted to Officier de la Légion d’honneur.

Jean Boulet had more than 9,000 flight hours, with over 8,000 hours in helicopters. He set 24 Fédération Aéronautique Internationale world records for speed, distance and altitude. Four of these are current.

Jean Boulet wrote L’Histoire de l’Helicoptere: Racontée par ses Pionniers 1907–1956, published in 1982 by Éditions France-Empire, 13, Rue Le Sueuer, 75116 Paris.

Jean Ernest Boulet died at Aix-en-Provence, in southern France, 15 February 2011, at the age of 90 years.

27–28 February 1947

North American Aviation P-82B-1-NA Twin Mustang 44-65168, “Betty Jo,” takes off from Hickam Field, 27 February 1947. (Hawaii Aviation)

27–28 February 1947: At 3:05 p.m., Hawaii Standard Time, (01:05 G.M.T.), Lieutenant Colonel Robert E. Thacker, Lieutenant John M. Ard, took off from Hickam Field on the island of Oahu, Territory of Hawaii, enroute non-stop to LaGuardia Airport, New York City, New York.

Thacker and Ard were assigned to the Air Materiel Command at Wright Field, Daytion, Ohio. Their airplane was a North American Aviation P-82B-1-NA Twin Mustang, 44-65168 (North American serial number 123-43754). The fighter had been named Betty Jo, in honor of Thacker’s wife. (The painter mistakenly applied the name as Betty Joe.)

Betty Jo had been modified by North American Aviation at El Segundo, California, in preparation for its long-distance flight. The fighter’s armor was removed, as were the six Colt MG 53-2 .50-caliber aircraft machine guns. Additional internal fuel capacity was added, and the P-82 was equipped with four large external fuel tanks. The Twin Mustang’s fuel capacity was 2,215 gallons (8,385 liters).

Thacker and Ard climbed to 13,000 feet (3,962 meters) after takeoff. As the fuel was burned off, the P-82 was able to climb higher. Most of the flight was made between 19,000 and 22,000 feet (5,791–6,706 meters).

After burning off the fuel in the four external tanks, Thacker tried to jettison them, but a mechanical problem prevented three tanks from being released. This resulted in adverse yaw and excessive drag for the overland portion of the flight. Colonel Thacker used the weight of his leg on the control stick to counteract the yaw.

Betty Jo, flying at 20,000 feet (6,096 meters), crossed the California coast near Point Arena at 12:34 a.m., Pacific Standard Time (08:34 G.M.T.), 6 hours, 59 minutes after takeoff. The P-82 passed north of Reno, Nevada, at 1:00 a.m. EST (09:00 G.M.T.), and Humboldt, Nevada, 23 minutes later.

Thacker and Ard next flew over Ogden, Utah, at 3:12 a.m., Mountain Standard Time (10:12 G.M.T.), and Laramie, Wyoming, at 4:05 MST (10:05 G.M.T.). They reported over Chicago at 6:49 a.m., Central Standard Time (12:49 G.M.T.), and Detroit at 8:38 a.m., CST (14:38 G.M.T.).

Betty Jo crossed overhead at LaGuardia Airport at 11:06 a.m., Eastern time (16:06 G.M.T.) and landed there at 11:08:34 a.m. (16:08:34 G.M.T.) The elapsed time from take off at Hickam Field to overhead LaGuardia was 14 hours, 31 minutes. The total duration of the flight was 14 hours, 33 minutes, 34 seconds.

On arrival at LaGuardia, only 60 gallons (227 liters) of fuel remained on board the Twin Mustang.

The Great Circle distance between Hickam and LaGuardia is s 4,324.32 nautical miles (4,976.34 statute miles/8,008.65 kilometers). Betty Jo averaged 297.89 knots (342.81 miles per hour/551.69 kilometers per hour) over the course.

Betty Jo is the ninth production North American Aviation P-82B-1-NA Twin Mustang. The airplane was designed toward the end of World War II as a very long range escort fighter operated by two pilots. It was built using two lengthened P-51H Mustang fuselages and standard left and right wings. A center wing section and horizontal stabilizer joined the two fuselages.

The P-82B was 39 feet, 1 inch (11.913 meters) long, with a wingspan of 51 feet, 3 inches  (15.621 meters) and overall height of 11 feet, 10 inches ( meters) in three-point position. The airplane’s empty weight is 13,405 pounds (6,080 kilograms), and maximum gross weight, 22,000 pounds (9,979 kilograms).

The P-82B-1-NA Twin Mustang was powered by liquid-cooled, supercharged, 1,649-cubic-inch-displacement (27.04-liter) Packard V-1650-19 and -21 Merlin single overhead cam (SOHC) 60° V-12 engines. They drove counter rotating Aeroproducts four-bladed propellers. through a 0.479:1 gear reduction. The V-1650-19 was rated at 1,700 horsepower at 3,000 r.p.m. at 19¾ inches of boost for takeoff, with military power rating of 2,200 horsepower at 3,000 r.p.m. at Sea Level, and 1,875 horsepower at 17,000 feet (5,182 meters). At 1,770 pounds (803 kilograms), the V-1650-19 was the heaviest Packard Merlin variant produced.

The P-82B had a maximum speed of 482 miles per hour (776 kilometers per hour) at 25,100 feet (7,650 meters) and its service ceiling was 41,600 feet (12,680 meters). Its range was 1,390 miles (2,237 kilometers).

The P-82B was armed with six air-cooled Colt Automatic Aircraft Machine Guns, Caliber .50,  MG 53-2, located in the center wing section, with 300 rounds of ammunition per gun. A pod containing eight additional .50-caliber machine guns could be installed under the center wing section. The Twin Mustang could also carry up to four 1,000 pound bombs, two 2,000 pound bombs, or twenty-five 5-inch rockets on underwing hard points.

After the United States Air Force was established as a separate military service in 1947, many aircraft designations were changed. The P-82B was redesignated as F-82B.

In September 1950, F-82B 44-65168 was transferred to the National Advisory Committee for Aeronautics (NACA) for use in testing ram jet engines at the Cleveland Aircraft Engine Research Laboratory. It was damaged in June 1957. The airplane was retired and turned over to the National Museum of the United States Air Force.

Robert E. Thacker was born 21 February 1918 in California. He was the second of four children of Percie C. Thacker and Margaret Eadie Thacker.

in 1939, Thacker was appointed an aviation cadet in the Air Corps, United States Army, and trained as a pilot at Brooks Field, San Antonio, Texas. He was commissioned a second lieutenant, Air Reserve, 21 June 1940.

On 3 March 1941, 2nd Lieutenant Thacker married Miss Betty Jo Smoot at Yuma, Arizona. They would be married for 71 years until she died in 1992.

On 1 November 1941, Thacker was appointed a first lieutenant, Army of the United States (A.U.S.).
