8 January 1944: At Muroc Army Air Field (later to become Edwards Air Force Base), the Lockheed Aircraft Corporation’s chief engineering test pilot, Milo Garrett Burcham, took the prototype Model L-140, the Army Air Forces XP-80 Shooting Star, 44-83020, for its first flight.

Tex Johnston, who would later become Boeing’s Chief of Flight Test, was at Muroc testing the Bell Aircraft Corporation XP-59 Airacomet. He wrote about the XP-80’s first flight in his autobiography:

Early on the morning of the scheduled first flight of the XP-80, busload after busload of political dignitaries and almost every general in the Army Air Force arrived at the northwest end of the lake a short distance from our hangar. Scheduled takeoff time had passed. I was afraid Milo was having difficulties. Then I heard the H.1B fire up, and he taxied by on the lake bed in front of our ramp. What a beautiful bird—another product of Kelly Johnson, Lockheed’s famed chief design engineer—tricycle gear, very thin wings, and a clear-view bubble canopy. Milo gave me the okay sign.

This was the initial flight of America’s second jet fighter, and what a flight it was. Milo taxied along in front of generals and politicians, turned south and applied full power. I could see the spectators’ fingers going in their ears. The smoke and sand were flying as the engine reached full power, and the XP-80 roared down the lake. Milo pulled her off, retracted gear and flaps, and held her on the deck. Accelerating, he pulled up in a climbing right turn, rolled into a left turn to a north heading, and from an altitude I estimated to be 4,000 feet [1,219 meters] entered a full-bore dive headed for the buses. He started the pull-up in front of our hangar and was in a 60-degree climb when he passed over the buses doing consecutive aileron rolls at 360 degrees per second up to 10,000 feet [3,048 meters]. He then rolled over and came screaming back. He shot the place up north and south, east and west, landed and coasted up in front of the spectators, engine off and winding down. I have never seen a crowd so excited since my barnstorming days. I returned to the office and dictated a wire to [Robert M.] Stanley [Chief Test Pilot, Bell Aircraft Corporation]WITNESSED LOCKHEED XP-80 INITIAL FLIGHT STOP VERY IMPRESSIVE STOP BACK TO DRAWING BOARD STOP SIGNED, TEX I knew he would understand.

A few minor problems caused Burcham to end the flight after approximately five minutes but these were quickly resolved and flight testing continued.

The XP-80 was the first American airplane to exceed 500 miles per hour (805 kilometers per hour) in level flight.

The Lockheed XP-80 was designed by Clarence L. “Kelly” Johnson and a small team of engineers that would become known as the “Skunk Works,” in response to a U.S. Army Air Corps proposal to build a single-engine fighter around the de Havilland Halford H.1B Goblin turbojet engine. (The Goblin powered the de Havilland DH.100 Vampire F.1 fighter.)

Lockheed Aircraft Corporation was given a development contract which required that a prototype be ready to fly within just 180 days.

The XP-80 was a single-seat, single-engine airplane with straight wings and retractable tricycle landing gear. Intakes for engine air were placed low on the fuselage, just forward of the wings. The engine exhaust was ducted straight out through the tail. For the first prototype, the cockpit was not pressurized but would be on production airplanes.

As was customary for World War II U.S. Army Air Forces aircraft, the prototype was camouflaged in non-reflective Dark Green with Light Gull Gray undersides. The blue and white “star and bar” national insignia was painted on the aft fuselage, and Lockheed’s winged-star corporate logo was on the nose and vertical fin. Later, the airplane’s radio call, 483020 was stenciled on the fin in yellow paint. The number 20 was painted on either side of the nose in large block letters. Eventually the tip of the nose was painted white and a large number 78 was painted just ahead of the intakes in yellow block numerals. Early in the test program, rounded tips were installed on the wings and tail surfaces. This is how the XP-80 appears today.

The XP-80 is 32 feet, 911/16 inches (9.9997 meters) long with a wingspan of 37 feet, ⅞-inch (11.2998 meters) and overall height of 10 feet, 21/16 inches (3.1004 meters). It had a Basic Weight for Flight Test of 6,418.5 pounds (2,911.4 kilograms) and Gross Weight (as actually weighed prior to test flight) of 8,859.5 pounds (4,018.6 kilograms).

The Halford H.1B Goblin used a single-stage centrifugal-flow compressor, sixteen combustion chambers, and single-stage axial-flow turbine. It had a straight-through configuration rather than the reverse-flow of the Whittle turbojet from which it was derived. The H.1B produced 2,460 pounds of thrust (10.94 kilonewtons) at 9,500 r.p.m., and 3,000 pounds (13.34 kilonewtons) at 10,500 r.p.m. The Goblin weighed approximately 1,300 pounds (590 kilograms).

The XP-80 has a maximum speed of 502 miles per hour (808 kilometers per hour) at 20,480 feet (6,242 meters) and a rate of climb of 3,000 feet per minute (15.24 meters per second). The service ceiling is 41,000 feet (12,497 meters).

Unusual for a prototype, the XP-80 was armed. Six air-cooled Browning AN-M2 .50-caliber machine guns were placed in the nose. The maximum ammunition capacity for the prototype was 200 rounds per gun.

The Halford engine was unreliable and Lockheed recommended redesigning the the fighter around the larger, more powerful General Electric I-40 (produced by GE and Allison as the J33 turbojet). The proposal was accepted and following prototypes were built as the XP-80A.

Lockheed built 1,715 P-80s for the U.S. Air Force and U.S. Navy. They entered combat during the Korean War in 1950. A two-seat trainer version was even more numerous: the famous T-33A Shooting Star.

Lockheed XP-80 Shooting Star 44-83020 was used as a test aircraft and jet trainer for several years. In 1949, it was donated to the Smithsonian Institution. 44-83020 is on display at the Jet Aviation exhibit of the National Air and Space Museum. It was restored beginning in 1976, and over the next two years nearly 5,000 man-hours of work were needed to complete the restoration.

5 January 1956: The prototype Piasecki Helicopter Company YH-16A-PH Transporter twin-turboshaft, tandem-rotor helicopter, serial number 50-1270, was returning to Philadelphia from a test flight, when, at approximately 3:55 p.m., the aft rotor desynchronized, collided with the forward rotor and the aircraft broke up in flight. It crashed at the Mattson Farm on Oldman’s Creek Road, near Swedesboro, New Jersey, and was completely destroyed.

Test pilots Harold W. Peterson and George Callahan were killed.

It was determined that a bearing associated with an internal coaxial shaft supporting test data equipment had seized, causing the rotor shaft to fail.

At the time, the YH-16 was the largest helicopter in the world. The United States Air Force intended it as a very-long-range rescue helicopter, while the U.S. Army expected it to serve as a heavy lift cargo and troop transport.

The YH-16A had a fuselage length of 78 feet (23.774 meters), and both main rotors were 82 feet (24.994 meters) in diameter. With rotors turning, the overall length was 134 feet (40.843 meters). Their operating speed was 125 r.p.m. Overall height of the helicopter was 25 feet (7.62 meters). The helicopter’s empty weight was 22,506 pounds (10,209 kilograms) and the gross weight was 33,577 pounds (15,230 kilograms).

YH-16 50-1269 was powered by two 2,181.2-cubic-inch-displacement (35.74 liter) air-cooled, supercharged Pratt & Whitney Twin Wasp E2 (R-2180-11) two-row, fourteen-cylinder radial engines with a Normal Power Rating of 1,300 horsepower at 2,600 r.p.m. at 8,000 feet (2,438 meters), and 1,650 horsepower at 2,600 r.p.m., for Takeoff.

The second YH-16A, 50-1270, was modified while under construction and was powered by two Allison Division YT38-A-10 turboshaft engines which produced 1,800 shaft horsepower, each. This made the YH-16A the world’s first twin-engine turbine-powered helicopter.

The cruise speed of the YH-16A was 146 miles per hour (235 kilometers per hour). In July 1955, Peterson and Callahan had flown 50-1270 to an unofficial record speed of 165.8 miles per hour (266.83 kilometers per hour). The service ceiling was 19,100 feet (5,822 meters) and the maximum range for a rescue mission was planned at 1,432 miles (2,305 kilometers).

After the accident, the H-16 project was cancelled.

31 December 1938: Boeing Model 307 Stratoliner NX19901 made its first flight at Boeing Field, Seattle, Washington. The test pilot was Eddie Allen, with co-pilot Julius A. Barr.

The Model 307 was a four-engine commercial airliner that used the wings, tail surfaces, engines and landing gear of the production B-17B Flying Fortress heavy bomber. The fuselage was circular in cross section to allow for pressurization. It was the first pressurized airliner and because of its complexity, it was also the first airplane to include a flight engineer as a crew member.

The Associated Press news agency reported:

Test Of Big Craft Begins

     SEATTLE, Dec. 31—(AP)—The world’s first plane, designed for flying in the sub-stratosphere, the new Boeing “Stratoliner”, performed “admirably” in a 42-minute first test flight in the rain today.

     The big ship, with a wingspread of 107 feet, three inches, climbed to 4,000 feet, the ceiling, and cruised between here, Tacoma and Everett. Speed was held down to 175 miles an hour.

     “The control and stability and the way it handled were very nice,” Edmund T. Allen, pilot, said. “She performed admirably.”

     The 33-passenger ship was built to fly at altitudes of 20,000 feet.

     No more tests are planned until next week. The supercharging equipment for high altitude flights will be installed later.

Giant ‘Stratoliner” Wheeled From Factory, On First Flight

SEATTLE, Dec. 31—(AP)—The newest thing in aviation—a giant, 33-passenger stratoliner named and built by Boeing Aircraft Company—met enthusiastic approval of its test pilot today after preliminary test runs.

     Scarcely 24 hours after it left the factory, the newest Boeing plane tested its wings yesterday. Test Pilot Edmund T. Allen taxied the plane along the ground, gunned it a bit and flew it in the air a short time at an altitude from 15 to 30 feet.

     Allen did not class the short hop as the ship’s maiden flight, which he said formally remained to be made, probably within a week.

     He said the big ship, minus general airplane characteristics, would not require any super-airports as the demonstration showed it would be able to take off and land at any ordinary-sized field.

     The stratoliner has four 1,100-horsepower motors which will enable it to cruise at an altitude of four miles at a speed of more than four miles a minute.

     Most unusual feature of the silver colored plane is the shape of the cabin, which bears a distinct resemblance to a metal dirigible. The cabin is circular throughout its length of 74 feet, four inches.

     The shape was adopted because of the necessity of sealing the cabin so passengers can enjoy low-level atmospheric conditions while soaring at high altitudes. The door, instead of opening outwards, is opened from the inside, so that the higher air pressure in the cabin will keep it sealed.

     The stratoliner’s wings compare in design with the Boeing flying fortresses but because of the larger cabin, the wing span is 107 feet, three inches, greater than that of the bombers, the new plane’s height is 17 feet, three inches.

     “Outside of scientific and engineering circles the substratosphere has been generally regarded as something far away and mystical, but now it is being brought ‘down to earth,’ C. L. Engtvedt, president of Boeing said.

     “The stratoliner will fly below the true stratosphere, but above the heavy air belt that brews surface weather conditions. Here we get most of the benefits of the stratosphere without getting into complex problems of flight in the extremely rare atmosphere and low temperature of the true stratosphere,” he said.

     Engtvedt predicted stratosphere type planes would lend a tremendous stimulus to the growth of air transportation.

     The first three stratoliners are being built for pan-American airways. Six more are in the course of construction for buyers whose identity has not been announced.

Eugene Register-Guard, Vol. 95, No. 1, January 1, 1939 at Page 3,  Columns 5 and 6

On March 18, 1939, during its 19th test flight, the Stratoliner went into a spin, then a dive. It suffered structural failure of the wings and horizontal stabilizer when the flight crew attempted to recover. NX19901 was destroyed and all ten persons aboard were killed.¹

The Boeing Model 307 was operated by a crew of five and could carry 33 passengers. It was 74 feet, 4 inches (22.657 meters) long with a wingspan of 107 feet, 3 inches (32.690 meters) and overall height of 20 feet, 9½ inches (6.337 meters). The wings had 4½° dihedral and 3½° angle of incidence. The empty weight was 29,900 pounds (13,562.4 kilograms) and loaded weight was 45,000 pounds (20,411.7 kilograms).

The airliner was powered by four air-cooled, geared and supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Cyclone 9 GR-1820-G102 9-cylinder radial engines with a compression ratio of 6.7:1, rated at 900 horsepower at 2,200 r.p.m., and 1,100 horsepower at 2,200 r.p.m. for takeoff. These drove three-bladed Hamilton-Standard Hydromatic propellers through a 0.6875:1 gear reduction in order to match the engine’s effective power range with the propellers. The GR-1820-G102 was 4 feet, 0.12 inches (1.222 meters) long, 4 feet, 7.10 inches (1.400 meters) in diameter, and weighed 1,275 pounds (578 kilograms).

In 1944, the 307s were returned to TWA and they were sent back to Boeing for modification and overhaul. The wings, engines and tail surfaces were replaced with those from the more advanced B-17G Flying Fortress. The last one in service was retired in 1951.

Of the ten Stratoliners built for Pan Am and TWA, only one remains. Fully restored by Boeing, NC19903 is at the Stephen F. Udvar-Hazy Center of the Smithsonian Institution.

John L. “Jack” Swigert, Jr., was born at Denver, Colorado, 30 August 1931, the first of three children of John Leonard Swigert, a physician, and Virginia Seep Swigert. Interested in aviation from an early age, he was a licensed Private Pilot at age 16. He graduated from Denver’s East High School in 1949.

Jack Swigert, 1952.

Jack Swigert attended the University of Colorado in Boulder, Colorado. He was a member of the Air Force Reserve Officers Training Corps (AFROTC), played on the varsity football team, and was a member of the C Club. He graduated in 1953 with a Bachelor’s Degree in Mechanical Engineering. Following his graduation, Swigert was commissioned as a second lieutenant, United States Air Force Reserve.

Lieutenant Swigert flew fighters from bases in Japan and Korea, then after completing his active duty requirement, 2 October 1956, he  transferred to the Air National Guard. He served with the Massachusetts ANG and Connecticut ANG.

Swigert earned a Master of Science degree in Aerospace Engineering from Rensselaer Polytechnic Institute, Troy, New York, in 1965, as well as a Master of Business Administration degree from the University of Hartford at Hartford, Connecticut.

While flying with the Air Guard, Swigert also worked for North American Aviation, Inc., as an engineering test pilot, and then for Pratt & Whitney.

He became one of 19 men selected as crewmembers of NASA’s Apollo Program 1965. He requested an assignment as pilot of the Apollo Command and Service Module.

Swigert was a member of the support team for the Apollo 7 mission, and was then selected as Command Module Pilot for the Apollo 13 backup crew, along with John Watts Young and Charles M. Duke, Jr.  When the primary crew CMP, Ken Mattingly, was thought to have been exposed to measles, he was withdrawn from Apollo 13 and Jack Swigert took his place in the primary crew.

Apollo 13 was planned as the third lunar landing mission. The circumstances of its flight are well known. When disaster struck, all three astronauts performed an amazing feat as they had to improvise their safe return to Earth.

Swigert left NASA in 1977 and entered politics. He was elected to the U.S. House of Representatives in 1982, representing the the 6th District of Colorado.

On the night of 27 December 1982, before he could be sworn into office, John Leonard Swigert, Jr., aerospace engineer, fighter pilot, test pilot, astronaut and congressman, died from complications of cancer.

27 December 1951: The North American Aviation XFJ-2B Fury, Bu. No. 133756, made its first flight at Los Angeles International Airport with test pilot Robert Anderson Hoover at the controls.

The XFJ-2B was a prototype aircraft carrier-based fighter for the United States Navy and Marine Corps. It was modified from a standard production U.S. Air Force F-86E-10-NA Sabre day fighter. The primary difference was the substitution of four 20 mm Colt Mark 12 autocannon for the six .50-caliber Browning M-3 machine guns of the F-86E. 150 rounds per gun were carried. The aircraft was flown to the Naval Ordnance Test Station, Armitage Field, China Lake, California, for armament testing.

The second and third prototypes were unarmed but fitted with an arrestor hook, catapult points, folding wings and a lengthened nose gear strut to increase the fighter’s static angle of attack for takeoff and landings. These two prototypes were used for aircraft carrier trials.

Production FJ-2 Fury fighters were built at North American’s Columbus, Ohio plant, along with F-86F Sabres for the Air Force.

Robert A. Hoover was one of the world’s best known exhibition pilots. He was a fighter pilot in the U.S. Army Air Corps during World War II. While flying a British Supermarine Spitfire with the 52nd Fighter Group based at Sicily, he was shot down, captured, and held as a prisoner of war at Stalag Luft I in Germany.

After 16 months in captivity, Hoover escaped, stole a Luftwaffe Focke-Wulf Fw 190 and flew it to The Netherlands.

After the war, Bob Hoover trained as a test pilot at Wright Field, Ohio, and remained in the Air Force until 1948. He worked as a test pilot for the Allison Division of General Motors, and then went on to North American Aviation.

Bob Hoover was famous  for flying aerobatic demonstrations around the world in his yellow P-51D Mustang and a twin-engine Shrike Commander, both built by North American Aviation.

Robert Anderson Hoover died 25 October 2016 at the age of 94 years.
