13 October 1950: The prototype Lockheed L-1049 Super Constellation made its first flight at the Lockheed Air Terminal in Burbank, California.

With the expansion in commercial air travel immediately following World War II, airlines required transports with longer range and greater passenger and cargo capacity. They needed airplanes that could provide lower seat-per-mile operating costs than existing types.

To meet these needs, Lockheed considered discontinuing production of the the current L-749 Constellation in favor of developing a completely new turbojet-powered transport. But due to the the time required to design and produce such a completely new design, and the much greater fuel consumption of jet engines, Lockheed determined that the most efficient course would be to improve the existing L-749 Constellation’s design to increase its load carrying capability.

Design of the L-1049 Super Constellation started February 1950, with the design team led by Kelly Johnson.

Instead of building a complete new airplane, the original XC-69 prototype, which had been parked at Howard Hughes’ private airport near Culver City, was purchased by Lockheed and flown back to the Lockheed Air Terminal in Burbank. After the war, the Constellation prototype was sold to Howard Hughes’ Hughes Aircraft Company for $20,000 and registered as NX67900. In May 1950, Lockheed bought the prototype back from Hughes for $100,000 and it was again registered as NC25600. It had accumulated just 404 flight hours up to this time.

The XC-69 was cut into three sections. A 10 foot, 8.8 inch (3.272 meters) long, 11 foot, 7.3 inch (3.538 meter) diameter, cylindrical section was added forward of the front wing spar, and a 7 foot, 8 inch (2.337 meters) cylindrical section with the same diameter, aft of the rear spar.

The wings, fuselage and landing gear of the L-1049 were strengthened for increased gross weight. The height of the vertical fins was increased 2.5 inches (6.35 centimeters) for improved longitudinal stability. The cabin floor area was increased by 33% to 744 square feet, and cargo volume, 51% to 656 cubic feet.

The L-1049 had accommodations for 76–94 passengers and crew. (The L-749A Constellation carried 47–63). Other changes included a 25% increase in cockpit window height, and square passenger windows (a requirement of Northwest Airlines). The fuel load was increased by 5,000 pounds, and the range by 300 miles. The Super Constellation’s cruise speed was cruise speed 25–40 m.p.h. slower due to the increased weight.

L-1049 serial numbers 4001–4014 had cockpit stations for a pilot, copilot, flight engineer and an observer. Beginning with 4015, a radio operator’s station as added.

The L-1049 was powered by four air-cooled, direct-fuel-injected, 3,347.662 cubic-inch-displacement (54.858 liters) Wright Aeronautical Division 956C18CA1 eighteen-cylinder turbocompound radial engines with a compression ratio of 6.70:1. The turbocompound engine used captured exhaust gases to drive three Power Recovery Turbines. These PRTs were coupled to the engine’s crankshaft. This system added approximately 450 horsepower to the engine’s total power output.

The 956C18CA1 had a continuous power rating of 2,300 horsepower at 2,600 r.p.m., and 2,700 horsepower at 2,900 r.p.m. for takeoff. The engines turned three-bladed Hamilton Standard propellers through a 0.4375:1 propeller gear reduction. The engine was 6 feet, 6.47 inches (1.993 meters) long, 4 feet, 7.62 inches (1.413 meters) in diameter, and weighed 2,962 pounds (1,343.5 kilograms).

The L-1049 had a maximum speed (VNO) of 260 knots (299 miles per hour/482 kilometers per hour) from Sea Level to 11,000 feet (3,353 meters). Above that altitude, speed was reduced by 9 knots (10 miles per hour/17 kilometers per hour) for each 2,000 foot (610 meters) increase. Maneuvering speed (VA) was 180 knots (207 miles per hour/333 kilometers per hour). The maximum operating altitude was 25,000 feet (7,620 meters). The cabin was pressurized to 5.5 p.s.i. (0.379 Bar).

The Los Angeles Times reported:

“NEXT THING TO JET—Eighteen feet longer than the standard Connie, Lockheed’s new Super Constellation is announced “to bridge the gap between modern planes and the first American jet transport.” Fifty million dollars in orders have been received.”

LOCKHEED UNVEILS SUPERTRANSPORT

Giant Constellation Carries 110 Passengers
Is Forerunner of Transocean Jet Aircraft

     Lockheed’s new Super Constellation—18.4 feet longer than the standard Connie—was announced yesterday as “designed to bridge the gap between modern planes and the first Americanjet transport.”

     Similar in appearance to its famous predecessor, the prototype of the new ship was flown for the first time last Friday, out of Lockheed Air terminal, Burbank, officials said.

     It will be introduced into service with the latest type reciprocating engines, subsequently will be powered with new compound engine and finally will utilize turbo-prop engines as the final link with pure jet transports of the future.

     “The new transport will incorporate much of the proven design and equipment of the current Constellation,” Lockheed spokesmen said, “and at the same time will carry all available modern features that testing has proved worthwhile.”

     Among teh latter will be electro-pneumatic de-icing such as is used on Lockheed’s high-speed jet aircraft. Old-type rubber boot and hot air de-icing has been found inadequate for higher speeds and altitudes, it was explained.

     The Super Connie is described as “the first truly nonstop trans-Atalantic transport ever built, 50 m.p.h. faster on over-ocean runs than competitive airplanes.”

     Measuring 113 feet 7 inches from nose to tail, its cabin will carry 76 standard-fare passengers or up to 110 coach fare, 35% more than present Constellations, with 72% more space for baggage and cargo.

Big Navy Engines

     The Super Connie is said to be the only transport in the world that will accommodate the powerful new compound Wright engines now developing 3500 h.p. each on long-range P2V patrol bombers built for the Navy by Lockheed.

     Its structural strength is such  that it can carry wing-tip fuel tanks, as do military jets on long-range flights, should such a feature become desirable to operators.

     Fifty million dollars in orders already have been received for the new transport from two airline operators and the military services

29 September–1 October 1946: The third production Lockheed P2V-1 Neptune, Bureau of Aeronautics serial number (Bu. No.) 89082, departed Perth, Western Australia, enroute to the United States, non-stop. The aircraft commander was Commander Thomas D. Davies, United States Navy. Three other pilots, Commanders Eugene P. Rankin and Walter S. Reid, and Lieutenant Commander Roy H. Tabeling, completed the crew.

The purpose of the flight was to demonstrate the long-distance capabilities of the Navy’s new bomber. A memorandum from Chief of Naval Operations, Fleet Admiral Chester A. Nimitz, to the Secretary of the Navy suggested:

“For the purpose of investigating means of extension of present patrol aircraft ranges, physiological limitations on patrol plane crew endurance and long-range navigation by pressure pattern methods, it is proposed to make a nonstop flight of a P2V-1 aircraft from Perth, Australia, to Washington, D.C., with the possibility, weather permitting, of extending the flight to Bermuda.”

The Lockheed Aircraft Corporation P2V Neptune was a twin-engine, long-range patrol bomber normally operated by a crew of eight. The first production variant, the P2V-1, was 75 feet, 4 inches (22.962 meters) long with a wingspan of 100 feet (30.48 meters) and overall height of 28 feet, 6 inches (8.687 meters). Empty weight was 33,720 pounds (15,295 kilograms) and gross weight was 61,153 pounds (27,739 kilograms).

The P2V-1 Neptune was powered by two air-cooled, supercharged, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Corporation Cyclone 18 779C18BB1  (R-3350-8), two-row 18-cylinder radial engines (also known as the Duplex-Cyclone). These engines were rated at 2,100 horsepower at 2,400 r.p.m., at Sea Level, and 2,400 horsepower at 2,600 r.p.m for takeoff. They drove four-bladed propellers through a 0.4375:1 gear reduction. The R-3350-8 was 6 feet, 5.8 inches (1.976 meters) long, 4 feet, 6.12 inches (12.375 meters) in diameter and weighed 2,796 pounds (1,268 kilograms)

These engines gave the P2V-1 a maximum speed of 303 miles per hour (488 kilometers per hour) at 15,300 feet (4,663 meters). The service ceiling was 27,000 feet (8,230 meters) and range was 4,110 miles (6,614 kilometers).

Standard armament consisted of six .50-caliber machine guns, two torpedoes carried in the internal bomb bay, conventional bombs or up to twelve depth charges. Nuclear weapons could also be carried. Sixteen rockets could be carried under the wings.

The Turtle was modified by Lockheed to achieve the maximum possible range. All armament was deleted, including the nose gun turret. Additional fuel tanks were installed in the bomb bay, rear fuselage and the outer wings. Wing tip fuel tanks were also added. These could be jettisoned when empty to reduce weight and aerodynamic drag. Most electronic and other unnecessary equipment, such as crew oxygen, were also removed. An additional lubricating oil tank for the engines was installed in the nose gear bay.

The standard configuration R-3350-8 engines were replaced with two Wright Cyclone 18 779C18BB2s (R-3350-14). The -14 had the same normal power rating as the -8, but its takeoff power had been decreased to 2,300 horsepower at 2,800 r.p.m. Its propeller gear reduction was 0.5625:1. The dimensions were the same, but the -14 weighed 65 pounds (29 kilograms) less.

Four Jet Assisted Take Off (JATO) rockets were added, with two on each side of the fuselage.

The flight began at Pearce Aerodrome, six miles inland from the Indian Ocean, north of Perth, Western Australia. Because of concerns that the landing gear might collapse with the extreme overloaded condition, The Turtle was only partially fueled when it taxied to Runway 27. Once there, the fueling was completed, bringing the Neptune’s all-up weight to 85,561 pounds (38,810 kilograms)—24,408 pounds (11,071 kilograms)—12 tons beyond its normal gross weight.

At 6:00 p.m., the two Cyclone 18 engines were started and warmed up. With Commander Davies flying in the left seat and Commander Rankin in the right, the engines were advanced to takeoff power while Davies stood on the brakes. With instruments reading normal, he released the brakes and The Turtle began its takeoff roll. The time was 6:11 p.m., local.

As indicated airspeed reached 87 knots (100 miles per hour/161 kilometers per hour) the four JATO rockets were fired. Reaching 115 knots (132 miles per hour/213 kilometers per hour) the nose wheel lifted off the runway followed a few seconds later by the main wheels. With just 5 feet (1.5 meters) altitude, the landing gear was retracted. By the time the JATOs burned out, the P2V-1 had climbed to 20 feet (6 meters) and reached 130 knots. (150 miles per hour/241 kilometers per hour) Once over the Indian Ocean the four JATO rockets were jettisoned.

This was the heaviest takeoff by a two-engine airplane up to that time.

The overweight airplane very slowly gained altitude as it crossed over Australia and then the Coral Sea. The planned route was a Great Circle Course over New Guinea and then the Solomon Islands.

With four pilots aboard, the crew rotated positions every two hours.

By dawn of the second day airborne, The Turtle crossed over the Hawaiian Islands chain at Maro Reef, between Midway and Oahu. Headwinds were pushing the patrol bomber southward of the intended course, but Commander Davies elected to allow the airplane to drift as correcting for it would have slowed their flight by turning more directly into the wind and would use more fuel. The planned route would have crossed the West Coast of the United States near Seattle, Washington, but the actual landfall was several hundred miles to the south, along the northern California coast.

The empty wing tip tanks were jettisoned before they crossed the shoreline just north of San Francisco at 9:16 p.m., 30 September.

As The Turtle flew across the Sierra Nevada and Rocky Mountains, and the western United States, it encountered severe weather with turbulence, freezing rain, snow and ice. They passed Salt Lake City, Utah, at dawn of the third day. Weather conditions had improved.

The adverse weather had cost additional fuel and calculations indicated that the planned destination of Washington, D.C., was now beyond their range. Commander Davies decided that the flight would end at NAS Columbus, Ohio.

The Lockheed Neptune’s wheels touched down at 1:28 p.m, 1 October. The four Naval Aviator’s and their bomber had flown 18,081.99 kilometers (11,235.63 miles). This set a new Fédération Aéronautique Internationale (FAI) World Record for Distance in a Straight Line Without Landing.¹ The duration of the flight was 55 hours, 17 minutes.

Secretary of the Navy James V. Forrestal awarded each pilot the Distinguished Flying Cross.

P2V-1 Bu. No. 89082 was used as a test aircraft until it was retired in 1953 and put on display at NAS Norfolk, Virginia.

The last operational antisubmarine warfare flight by a Lockheed Neptune, an SP-2H, was flown 20 February 1970. The co-pilot on the mission was Rear Admiral Thomas D. Davies.

Note on the name of the airplane: The Turtle was named after Operation Turtle,  a joint U.S. Navy/Lockheed project to maximize the range and endurance of the P2V Neptune patrol bomber. The name with a cartoon of a turtle with a naval officer’s cap and a cape, smoking a pipe and pedaling to turn a propeller was painted on the airplane’s nose. U.S. Navy press releases called it “The Truculent Turtle” and newspapers picked up this nickname, by which the airplane is generally referred to. There is no evidence that the airplane’s crew ever described the airplane as “truculent”:

“. . . having a bad state of mind, or behaving in a threatening manner. . . .”

24–25 August 1932: Amelia Earhart flew her Lockheed Model 5B Vega, NR7952, from Los Angeles, California, to Newark, New Jersey, a distance of 3,939.25 kilometers (2,447.74 miles), in 19 hours, 5 minutes. She had departed Los Angeles Municipal Airport (now known as LAX) at 7:26:54 p.m. Pacific Time, 24 August, and landed at Newark Municipal Airport at 11:30 a.m. Eastern Time the following day. This set a Fédération Aéronautique Internationale (FAI) women’s World Record for Distance in a Straight Line Without Landing.¹ Her average speed for the flight was 206.42 kilometers per hour (128.27 miles per hour).

National Aeronautics Association Certificate of Record, issued on behalf of the Fédération Aéronautique Internationale.

Amelia Earhart was the first woman to fly solo coast-to-coast. Less than a year later, she would break her own record by almost two hours.

Built by the Lockheed Aircraft Company, the Model 5 Vega was a single-engine high-wing monoplane. The fuselage was molded wood monocoque construction and the wing was cantilevered wood. The Vega 5B is 27 feet, 6 inches (8.382 meters) long with a wingspan of 41 feet (12.497 meters) and overall height of 8 feet, 2 inches (2.489 meters). Its empty weight is 1,650 pounds (748.4 kilograms) and gross weight is 4,375 pounds (1,985 kilograms).

Aircraft Registration Certificate, Lockheed Vega 5B, serial number 22, NC7952.

Earhart’s modified Vega 5B is powered by an air-cooled, supercharged 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp C nine cylinder radial engine. The Wasp C was rated at 420 horsepower at 2,000 r.p.m. at Sea Level.² It was 3 feet, 6.63 inches (1.083 meters) long, 4 feet, 3.44 inches (1.307 meters) in diameter, and weighed 745 pounds (338 kilograms). It drove a two-bladed Hamilton Standard controllable-pitch propeller through direct drive.

Just three months earlier, Earhart had flown solo across the Atlantic Ocean in this same airplane, which she called her “Little Red Bus.” Today, Lockheed Vega NR7952 is in the collection of the Smithsonian Institution National Air and Space Museum.

15 August 1935: Two of the most famous men of their time, Wiley Hardeman Post and William Penn Adair (“Will”) Rogers, were killed in an airplane crash near Point Barrow, Alaska.

Post, a pioneering aviator who had twice flown around the world—once, solo—and helped develop the pressure suit for high altitude flight, was exploring a possible air mail route from the United States to Russia. His friend, world famous humorist Will Rogers, was along for the trip.

Post’s airplane was a hybrid, built from the fuselage of a former Transcontinental & Western Air, Inc., Lockheed Model 9E Orion Special, NC12283, combined with a wing from a Lockheed Model 7 Explorer. T&WA operated the Orion for two years before selling it to Charles Babb, Glendale, California. Babb installed the salvaged wing from a modified Lockheed Model 7 Explorer, Blue Flash, NR101W, which had crashed in Panama in 1930.

The Orion’s standard 450 horsepower Pratt & Whitney Wasp SC1 engine was replaced with an air-cooled, supercharged, 1,343.8-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S3H1 nine-cylinder radial engine (serial number 5778), rated at 550 horsepower at 2,200 r.p.m. to 5,000 feet (1,524 meters), and 600 horsepower at 2,250 r.p.m. for takeoff. A three-bladed Hamilton Standard variable-pitch propeller was used. Both the SC1 and S3H1 were direct drive engines. The S3H1 was 3 feet, 7.01 inches (1.093 meters) long and 4 feet, 3.60 inches (1.311 meters) in diameter. It weighed 865 pounds (392 kilograms).

Post also wanted to replace the retractable landing gear with pontoons for water landings.

Lockheed engineers were of the opinion that the hybrid aircraft and the other modifications which were requested by Post were dangerous and refused to do the work. Pacific Airmotive, also located in Burbank, California, however, agreed to modify the airplane. Several names were used to describe the hybrid airplane, such as “Lockheed Aurora,” as well as others perhaps less polite. It was given the restricted registration NR12283.

NR12283 was 27 feet, 6 inches (8.382 meters) long with a wingspan of 48 feet, 6 inches (14.783 meters). The wing area was 313 square feet (29.079 square meters).

After several days of flying from Seattle and through Alaska, Post and Rogers were nearing Point Barrow on the northern coast of the continent. They encountered dense fog and landed on Walakpa Bay, about 13 miles (21 kilometers) southwest of the village of Barrow.

After talking with a local resident, Clair Okpheah, they taxied back on the lagoon and took off to the north. Post banked to the right, but at about 50 feet (15 meters) the engine stopped. NR12283 pitched down, rolled to the right, and then its right wing struck the mud. The right wing and pontoon were torn off and the airplane crashed upside down. Post and Rogers died.

Clair Okpheah ran to Barrow for help. When a rescue party arrived 16 hours after the crash, the men recovered the bodies of Post and Rogers. It was noted that Wiley Post’s wristwatch had stopped at 8:18 p.m.

6 August 1945: After serving three combat tours flying the Lockheed P-38 Lightning in the Southwest Pacific, Major Richard Ira Bong, Air Corps, United States Army, was assigned as an Air Force acceptance test pilot for new Lockheed P-80 Shooting Star jet fighters at the Lockheed Air Terminal, Burbank, California.

The P-80A was a brand new jet fighter, and Major Bong had flown just 4 hours, 15 minutes in the type during 12 flights.

Shortly after takeoff in P-80A-1-LO 44-85048, the primary fuel pump for the turbojet engine failed. A back-up fuel pump was not turned on. The Shooting Star rolled upside down and Bong bailed out, but he was too low for his parachute to open and he was killed. The jet crashed at the intersection of Oxnard Street and Satsuma Avenue, North Hollywood, California, and exploded.

Richard I. Bong was known as the “Ace of Aces” for scoring 40 aerial victories over Japanese airplanes between 27 December 1942 and 17 December 1944 while flying the Lockheed P-38 Lightning. He was awarded the Medal of Honor, which was presented by General Douglas MacArthur, 12 December 1944. [The following day, General MacArthur was promoted to General of the Army.]

The citation for Major Bong’s Medal of Honor reads: “For conspicuous gallantry and intrepidity in action above and beyond the call of duty in the Southwest Pacific area from 10 October to 15 November 1944. Though assigned to duty as gunnery instructor and neither required nor expected to perform combat duty, Major Bong voluntarily and at his own urgent request engaged in repeated combat missions, including unusually hazardous sorties over Balikpapan, Borneo, and in the Leyte area of the Philippines. His aggressiveness and daring resulted in his shooting down eight enemy airplanes during this period.”

The Lockheed P-80-1-LO was the United States’ first operational jet fighter. It was a single-seat, single-engine low-wing monoplane powered by a turbojet engine. The fighter was 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) ¹ 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 -0° 30′ at the tip. 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).² 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.

² 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.
