27 January 1939: First Lieutenant Benjamin Scovill Kelsey, Air Corps, United States Army, made the first flight of the prototype Lockheed XP-38 Lightning, serial number 37-457, at March Field, Riverside County, California.
This was a short flight. Immediately after takeoff, Kelsey felt severe vibrations in the airframe. Three of four flap support rods had failed, leaving the flaps unusable.
Returning to March Field, Kelsey landed at a very high speed with a 18° nose up angle. The tail dragged on the runway. Damage was minor and the problem was quickly solved.
Designed by an engineering team led by Hall L. Hibbard, which included the legendary Clarence L. “Kelly” Johnson, the XP-38 was a single-place, twin-engine fighter designed for very high speed and long range. It was an unusual configuration with the cockpit and armament in a center nacelle, with two longitudinal booms containing the engines and propellers, turbochargers, radiators and coolers. The Lightning was equipped with tricycle landing gear. The nose strut retracted into the center nacelle and the two main gear struts retracted into bays in the booms. To reduce drag, the sheet metal used butt joints with flush rivets.
The prototype had been built built at Lockheed’s factory in Burbank, California. On the night of 31 December 1938/1 January 1939, it was transported to March Field aboard a convoy of three trucks. Once there, the components were assembled by Lockheed technicians working under tight security.
The XP-38 was 37 feet, 10 inches (11.532 meters) long with a wingspan of 52 feet (15.850 meters) and overall height of 12 feet, 10 inches (3.952 meters). Its empty weight was 11,507 pounds (5,219.5 kilograms). The gross weight was 13,904 pounds (6,306.75 kilograms) and maximum takeoff weight was 15,416 pounds (6,992.6 kilograms).
The Lightning was the first production airplane to use the Harold Caminez-designed, liquid-cooled, supercharged, 1,710.60-cubic-inch-displacement (28.032 liter) Allison Engineering Company V-1710 single overhead cam 60° V-12 engines. When installed on the P-38, these engines rotated in opposite directions. The XP-38 used a pair of experimental C-series Allisons, with the port V-1710-C8 (V-1710-11) engine being a normal right-hand tractor configuration, while the starboard engine, the V-1710-C9 (V-1710-15), was a left-hand tractor. Through a 2:1 gear reduction, these engines drove the 11-foot (3.353 meters) diameter, three-bladed Curtiss Electric variable-pitch propellers inward to counteract the torque effect of the engines and propellers. (Viewed from the front of the airplane, the XP-38’s starboard propeller turned clockwise, the port propeller turned counter-clockwise. The direction of rotation was reversed in the YP-38 service test prototypes and production P-38 models.) The engines have long propeller gear drive sections to aid in streamlining aircraft, and are sometimes referred to as “long-nose Allisons.”
The V-1710-11 and -15 had a compression ratio of 6.65:1. They had a continuous power rating of 1,000 horsepower at 2,600 r.p.m. at Sea Level, and 1,150 horsepower at 2,950 r.p.m. for takeoff. The combination of a gear-driven supercharger and an exhaust-driven General Electric B-1 turbosupercharger allowed these engines to maintain their rated power levels to an altitude of 25,000 feet (7,620 meters).
The -11 and -15 were 7 feet, 10.46 inches (2.399 meters) long. The -11 was 3 feet, 6.59 inches (1.082 meters) high and 2 feet, 4.93 inches (0.7348 meters) wide. It weighed 1,300 pounds (589.7 kilograms). The -15 was 3 feet, 4.71 inches (1.034 meters) high, 2 feet, 4.94 inches (0.7351 meters) wide, and weighed 1,305 pounds (591.9 kilograms).
The XP-38 had a maximum speed of 413 miles per hour (664.66 kilometers per hour) at 20,000 feet (6,096 meters) and a service ceiling of 38,000 feet (11,582.4 meters).
The XP-38 was unarmed, but almost all production Lightnings carried a 20 mm auto cannon and four Browning .50-caliber machine guns grouped together in the nose. They could also carry bombs or rockets and jettisonable external fuel tanks.
The prototype XP-38 was damaged beyond repair when, on approach to Mitchel Field, New York, 11 February 1939, both engines failed to accelerate from idle due to carburetor icing. Unable to maintain altitude, Lieutenant Kelsey crash landed on a golf course and was unhurt.
Testing continued with thirteen YP-38A pre-production aircraft and was quickly placed in full production. The P-38 Lightning was one of the most successful combat aircraft of World War II. By the end of the war, Lockheed had built 10,037 Lightnings.
26 January 1946: Colonel William Haldane Councill, U.S. Army Air Forces, a test pilot at the Flight Test Division, Wright Field, Ohio, made a record-breaking flight from Daugherty Field (Long Beach Airport), California, to overhead LaGuardia Airport, New York, in 4 hours, 13 minutes, 26 seconds. He was piloting a Lockheed P-80A-1-LO Shooting Star, serial number 44-85123. Colonel Councill flew as high as 41,000 feet (12,497 meters), but stayed at 35,000 feet (10,668 meters) for most of the flight. This flight set a new transcontinental speed record for the 2,457 miles (3,954 kilometers), averaging 584.82 miles per hour (941.18 kilometers per hour).
The National Aeronautic Association representative, John P. V. Heinmuller, was the official timer. (Mr. Heinmuller was the Chief Timer of both the N.A.A. and the Fédération Aéronautique Internationale. He was president of the Longines-Wittnauer Watch Co., inc. He had also timed Lindbergh’s transatlantic flight in 1927. Mr. Heinmuller was the author of Man’s Fight to Fly: Famous World-Record Flights and a Chronology of Aviation, 1944).
Colonel Councill was accompanied by two other P-80s flown by Captain John S. Babel and Captain Martin I. Smith. This was the longest non-stop flight by a jet aircraft up to that time.
Colonel Councill’s P-80A had been modified with the installation of a 100-gallon (379 liters) fuel tank in the nose in place of the standard armament of six machine guns. Along with 300-gallon (1,135 liters) wing tip tanks, the Shooting Star’s maximum fuel load had been increased to 1,165 gallons (4,410 liters).¹
The P-80s flown by Captains Babel and Smith also had the nose fuel tank installed, but carried 150-gallon (569 liters) wing tip tanks. They had to stop at Topeka, Kansas, to refuel. Ground crews met them with four fuel trucks, and they were airborne in 4 minutes and 6 minutes, respectively.
William Haldane Councill was born 5 October 1911 at Bellevue, Pennsylvania. He was the second of four children of William Mansfield Councill, a manager for a fireproofing company, and Bertha Etta Wing Councill. He attended Perry High School, where he was a member of the Aero Club.
Bill Councill studied at the Carnegie Institute of Technology, Pittsburgh, Pennsylvania. He was a member of the Reserve Officers Training Corps (R.O.T.C.), and the Delta Upsilon (ΔΥ) fraternity. He was also a member of the Scabbard and Blade, and co-chairman of the Military Ball. Councill graduated in 1933 with the degree of Bachelor of Science in Mechanical Engineering (B.S.M.E.).
William H. Councill was commissioned as a second lieutenant, Engineer Reserve, 1 June 1933. He was appointed a flying cadet and trained as a pilot, 1 October 1933 to 14 October 1935. He then received a commission as a second lieutenant, Air Reserve.
Lieutenant Councill married Miss Lillie Louise Slay at Wahiawa Heights, Honolulu, Territory of Hawaii, 18 April 1936. They would have one daughter, Frances, born in 1943.
On 1 October 1938, Councill’s reserve commission was converted to second lieutenant, Air Corps, United States Army. Councill was promoted to first lieutenant, 1 October 1941.
During this time William Councill held a parallel commission in the Army of the United States. He was promoted to first lieutenant, A.U.S., 9 September 1940, and captain, A.U.S., 1 February 1942. On 1 March 1942, he was promoted to the rank of major, A.U.S. (A.C.), and to lieutenant colonel, 19 December 1942. On 3 July 1945, Councill advanced to the rank of colonel, A.U.S.
Colonel Councill was rated as a command pilot. During World War II, he flew 130 combat missions with the the Lockheed P-38 Lightning .Thirteenth Air Force in the southwest Pacific area. He is credited with shooting down three enemy aircraft, and was awarded the Distinguished Flying Cross for his actions in an air battle over the Solomons, 15 January 1943.
At 10:54 a.m., 5 April 1954, Colonel Councill took off from the Republic Aviation Company plant at Farmingdale, New York, in a Lockheed T-33A Shooting Star, en route to Langley Field, Virginia. He never arrived. An extensive search, other than locating a single wing tank, was unsuccessful. It was presumed that Councill went down in the Atlantic Ocean.
According to his commanding officer, Major General Earl W. Barnes,
“. . . He was a most capable, dependable and responsible officer who was conscientiously devoted to his tasks. His opinions on military matters were highly regarded by his superior officers. His pleasant personality, genial manner, and dry wit endeared him to the hearts of the many friends he had won during approximately twenty-one years of service in the United States Air Force. He was greatly beloved by those with whom he associated. . . I feel that our Country and the Air Force have lost an irreplaceable asset and a great leader.”

The Lockheed P-80-1-LO was the United States’ first operational jet fighter. It was a single-seat, single engine airplane, designed by a team of engineers led by Clarence L. (“Kelly”) Johnson. The prototype XP-80A, 44-83020, nicknamed Lulu-Belle, was first flown by test pilot Tony LeVier at Muroc Army Air Field (now known as Edwards Air Force Base) 8 January 1944.
The P-80A was a day fighter, and was not equipped for night or all-weather combat operations. The P-80A was 34 feet, 6 inches (10.516 meters) long with a wingspan of 38 feet, 10.5037 inches (11.84919 meters) ² and overall height of 11 feet, 4 inches (3.454 meters).
The leading edges of the P-80A’s wings were swept aft 9° 18′ 33″. They had an angle of incidence of +1° at the root and -1° 30′ twist. There was 3° 50′ dihedral. The total wing area was 237.70 square feet (22.083 square meters).
The fighter had an empty weight of 7,920 pounds (3,592 kilograms) and a gross weight of 11,700 pounds (5,307 kilograms). The maximum takeoff weight was 14,000 pounds (6,350 kilograms).
Early production P-80As were powered by either an Allison J33-A-9 or a General Electric J33-GE-11 turbojet engine. The J33 was a licensed version of the Rolls-Royce Derwent. It was a single-shaft turbojet with a 1-stage centrifugal compressor section and a 1-stage axial-flow turbine. The -9 and -11 engines were rated at 3,825 pounds of thrust (17.014 kilonewtons). The J33s were 8 feet, 6.9 inches (2.614 meters) long, 4 feet, 2.5 inches (1.283 meters) in diameter and weighed 1,775 pounds (805 kilograms).
The P-80A had a cruising speed of 445 miles per hour (716 kilometers per hour) at 20,000 feet (6,096 meters). Its maximum speed was 548 miles per hour (882 kilometers per hour) at 2,700 feet (823 meters) and and 501 miles per hour (806 kilometers per hour) at 34,700 feet (10,577 meters). The service ceiling was 45,000 feet (13,716 meters).
The P-80A Shooting Star was armed with six air-cooled Browning AN-M2 .50-caliber aircraft machine guns mounted in the nose.
Several hundred of the early production P-80 Shooting stars had all of their surface seams filled, and the airplanes were primed and painted. Although this process added 60 pounds (27.2 kilograms) to the empty weight, the decrease in drag allowed a 10 mile per hour (16 kilometers per hour) increase in top speed. The painted surface was difficult to maintain in the field and the process was discontinued.
On 3 June 1946, Lockheed P-80A-1-LO Shooting Star 44-85123, flown by Lieutenant Henry A. Johnson, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Closed Circuit of 1,000 Kilometers with an average speed of 745.08 kilometers per hour (462.97 miles per hour).³
On 2 September 1946, Major Gustav Lindquist won the Thompson Trophy Race, J Division, at the National Air Races, Cleveland, Ohio, 1946, with the same airplane, averaging 515.853 miles per hour (830.185 kilometers per hour) over a 180-kilometer (111.85-mile) course.
Today, 44-85123 is in the collection of the Air Force Flight Test Museum, Edwards Air Force Base.

² Wing span with rounded wing tips. P-80As with squared (“clipped”) tips had a wing span of 37 feet, 7.5037 inches (11.46819 meters).
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.
—Tex Johnston: Jet-Age Test Pilot, by A.M. “Tex” Johnston with Charles Barton, Smithsonian Books, Washington, D.C., 1 June 1992, Chapter 5 at Pages 127–128.
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.
29 December 1972: Eastern Air Lines Flight 401, a Lockheed L-1011 TriStar, was en route from John F. Kennedy International Airport (JFK), New York, to Miami International Airport (MIA), Florida, with a crew of 13 and 163 passengers. The flight was under the command of Captain Robert Albin Loft, a 32-year-veteran of Eastern Air Lines. The co-pilot was First Officer Albert John Stockstill, a former U.S. Air Force pilot who had flown with Eastern as a flight engineer for 12 years before upgrading to first officer the previous year. The Second Officer (flight engineer) was Donald Louis Repo. He was employed as a mechanic by Eastern in 1947, and had qualified as a flight engineer in 1955.
On approach to MIA, the flight crew lowered the landing gear. The indicator light for the nose gear did not illuminate. Captain Loft informed the Miami control tower that he was abandoning the approach and requested a holding pattern. Miami Approach Control placed Flight 401 in a “race track” pattern at 2,000 feet (610 meters), west of MIA.
The flight crew confirmed that the landing gear was operating properly, and confirmed that the incandescent light bulb for the gear position indicator was burned out. Still, all three members of the flight crew, as well as a fourth Eastern Air Lines employee who was in the cockpit, continued to investigate the light’s malfunction. While they did so, the airplane entered a very gradual descent which went unobserved by the crew.
The following partial transcript is from the airplane’s Cockpit Voice Recorder:
Miami Approach Control: “Eastern, ah Four Oh One how are things comin’ out there?” [2341:40]
Eastern Air Lines Flight 401: “Okay, we’d like to turn around and come back in.” [2341:44]
Miami Approach Control: “Eastern Four Oh One turn left heading one eight zero.” [2341:47]
First Officer: “We did something to the altitude.” [2342:05]
Captain: “What?” [2342:05]
First Officer: “We’re still at two thousand, right?” [2342:07]
At 11:42:12 p.m., Eastern Standard Time, Flight 401 impacted the surface of an Everglades swamp, 18.7 miles (30.1 kilometers) west-northwest of the end of Runway 9L. The TriStar hit the ground at 227 miles per hour (365 kilometers per hour) in a 28° left bank. Of the 176 persons on board, 99 were killed and 75 were injured. 2 of the injured died later.
The cause of the accident was “pilot error.” In the simplest terms, the flight crew failed in their primary responsibility to FLY THE AIRPLANE while they dealt with an inconsequential technical issue. At the time, this was the highest number of fatalities in an aircraft accident in the United States.
PROBABLE CAUSE: “The National Transportation Safety Board determines that the probable cause of this accident was the failure of the fight crew to monitor the flight instruments during the final 4 minutes of flight, and to detect an unexpected descent soon enough to prevent impact with the ground. Preoccupation with a malfunction of the nose landing gear position indicating system distracted the crew’s attention from the instruments and allowed the descent to go unnoticed.”
— Aircraft Accident Report, Eastern Air Lines, Inc. L-1011, N310EA, Miami, Florida, December 29, 1972, Report Number NTSB-AAR-73-14, Adopted 14 June 1973, Chapter 2.2 at Pages 23–24
Following the crash of Eastern Air Lines Flight 401, and the similar crash of a United Air Lines DC-8, Flight 173, at Portland, Oregon, 28 December 1978, airlines developed a system called Cockpit Resource Management to ensure that the flight crews stayed focused on cockpit priorities while dealing with unexpected issues.
Flight 401 was a Lockheed L-1011-385-1 TriStar, a long-range variant of the “wide body” airliner, FAA registration N310EA, (serial number N193A-1011) which had been delivered to Eastern Air Lines 18 August 1972 had entered service three days later. At the time of the crash it had just 986 hours total flight time (TTAF).
The L-1011 was a very technologically advanced airliner, operated by a flight crew of three, and could carry a maximum of 330 passengers. The –385 was 14 feet shorter than the previous TriStar versions, with a length of 164 feet, 2.5 inches (50.051 meters). It had longer wings, spanning 164 feet, 4 inches (50.089 meters). Its overall height was 55 feet, 4 inches (16.865 meters). Empty, it weighed 245,400 pounds (111,312 kilograms). The maximum takeoff weigh was 510,000 pounds (231,332 kilograms) and maximum landing weight, 368,000 pounds (166,922 kilograms).
N310EA was powered by three Rolls-Royce RB.211-22C turbofan engines, with two suspended on pylons under the wings and one in the rear of the fuselage. They produced 42,000 pounds of thrust (186.83 kilonewtons), each.
The L-1011-385-1 had a maximum speed of 0.95 Mach. Its cruising speed was 604 miles per hour (972 kilometers per hour). Range with maximum passengers was 6,151 miles (9,899 kilometers). The service ceiling was 43,000 feet (13,106 meters).
The Lockheed L-1011 was in production from 1968 to 1984. 250 of the airliners were built at Palmdale, California.
