12 April 1918: Allan and Malcolm Loughead, owners of the Loughead Aircraft Manufacturing Company of Santa Barbara, California, set speed and distance records as they flew their twin-engine, ten-place F-1 flying boat from Santa Barbara to San Diego. The F-1 traveled 211 miles in 3 hours, 1 minute.
Designed by friend and employee John Knudson (“Jack”) Northrop, and built in a garage on State Street, the F-1 was launched on a wooden ramp at West Beach.
The airplane was intended for the U.S. Navy, but the end of World War I ended the requirement for new airplanes.
The Loughead F-1 was a twin-engine, three-bay biplane flying boat operated by a crew of 2. It could carry 8–10 passengers. The airplane was 35 feet (10.668 meters) long. The span of the upper wing was 74 feet (22.555 meters) and the lower wing was 47 feet (14.326 meters). The height was 12 feet (3.658 meters). The F-1 had an empty weight of 4,200 pounds (1,905 kilograms) and gross weight of 7,300 pounds (3,311 kilograms).
The F-1 was powered by two right-hand tractor, water-cooled, normally-aspirated 909.22-cubic-inch-displacement (14.899 liters) Hall-Scott A-5-a single-overhead cam (SOHC) vertical inline six-cylinder engines with a compression ratio of 4.6:1. The A-5-a was a direct-drive engine. It was rated at 150 horsepower and produced 165 horsepower at 1,475 r.p.m. The engines were mounted on steel struts between the upper and lower wings. The engines turned two-bladed, fixed pitch propellers with a diameter of 8 feet, 8 inches ( meters) The Hall-Scott A-5-a was 5 feet, 2.5 inches (1.588 meters) long, 2 feet, inches (0.610 meters) wide and 3 feet, 7.875 inches (1.114 meters) high. It weighed 595 pounds (270 kilograms).
The F-1 had a cruise speed of 70 miles per hour (113 kilometers per hour) and maximum speed of 84 miles per hour (135 kilometers per hour).
The F-1 was converted to a land plane with tricycle undercarriage and redesignated F-1A. During an attempted transcontinental flight, it twice suffered engine failure and was damaged. Reconfigured as a flying boat, the airplane was used for sight-seeing before being sold. It was abandoned on a beach at Santa Catalina Island, off the coast of Southern California, and was eventually destroyed.
The Loughead Aircraft Manufacturing Company would go on to become one of the world’s leading aerospace corporations.
18 March 1937, 5:40 a.m.: Amelia Earhart and her crew sighted Diamond Head on the island of Oahu, Hawaiian Islands. The Electra landed at Wheeler Army Airfield, Honolulu, after an overnight flight from Oakland, California, completing the first leg of a planned around-the-world flight in 15 hours, 47 minutes.
Also aboard were Paul Mantz, Amelia’s friend and adviser, as co-pilot, navigator Captain Frederick Joseph Noonan, formerly of Pan American Airways, and Captain Harry Manning of United States Lines, acting as radio operator and navigator. The airplane was Earhart’s Lockheed Electra 10E Special, registration NR16020.
About an hour after takeoff from Oakland, California, the Electra overtook the Pan American Airways Hawaii Clipper, which had departed San Francisco Bay an hour-and-a-half before Earhart. She took photographs of the Martin M-130 flying boat.
In her log, Amelia Earhart described the sunset over the Pacific Ocean:
“. . . golden edged clouds ahead, then the golden nothingness of sunset beyond. . . The aft cabin is lighted with a weird green blue light, Our instruments show pink. The sky rose yellow. . . Night has come. The sea is lovely. Venus is setting ahead to the right. The moon is a life-saver. It gives us a horizon to fly by. . . .”
— Amelia: The Centennial Biography of an Aviation Pioneer, by Donald M. Goldstein and Katherine V. Dillon, Brassey’s, Wahington and London, 1997, Chapter 18 at Page 171.
On arrival at Hawaii, Earhart, saying that she was very tired, asked Paul Mantz to make the landing at Wheeler Field.
9 October 1955: Lieutenant Colonel Robert Ray Scott, United States Air Force, commanding officer, 510th Fighter Bomber Squadron, 405th Fighter Bomber Wing, Langley Air Force Base, Virginia, with Major Robert C. Ruby and Captain Charles T. Hudson, flew their Republic F-84F Thunderstreaks non-stop from Los Angeles Airport (LAX), on the southern California coastline, to overhead Floyd Bennett Field, New York. The elapsed time for the Colonel Scott’s flight was 3 hours, 46 minutes, 33.6 seconds. Two in-flight refuelings from Boeing KB-29 tankers were required.
A newspaper article from the following day describes the event:
2 Des Moines Pilots Break Speed Record
NEW YORK (AP) — Two air force pilots from Des Moines broke the speed record from Los Angeles to New York Wednesday, making a nonstop flight in less than four hours.
Lt. Col. Robert R. Scott, 34, flying a Republic F-84F Thunderstreak jet fighter, turned in the fastest time — 3 hours 46 minutes and 33 seconds. He averaged 649 miles an hour.
Just one minute behind was another Des Moines pilot, Maj. Robert C. Ruby, 32. His time was 3:47:33.
The old mark for the 2,445-mile route was 4:06:16, set Jan 2, 1954, by an air national guard pilot.
The pilots said they could have made faster time except for slow and obsolete in-flight refueling tanker planes.
A third pilot who shattered the old mark is Capt. Charles T. Hudson, 33, of Gulfport, Miss., who made the flight in 3:49:53.
Eight air force Thunderstreaks left Los Angeles in a mass assault on the record. Five dropped out through failure to make contact with refueling planes or other reasons. All reportedly landed safely.
While setting a Los Angeles–New York record, Scott failed to beat the navy’s time from San Diego, Calif., to New York — 2,438 miles, or seven miles shorter than Wednesday’s flight.
Flew Cougar Jet
Lt. Comdr. Francis X. Brady, 33, of Virginia Beach, Va., flew from San Diego in 3:45:30 on April 1, 1954, flying a Grumman F9F Cougar.
The air force planes flew at about 40,000 feet.
“The tankers used for refueling are much too obsolete and too old,” Scott commented on landing.
The jets had to slow to 200 m.p.h. from almost 650 to take on fuel.
Scott said he refueled twice — once near La Junta, Colo., and once near Rantoul, Ill.
Ruby and Hudson also said they could have made faster time if the tank planes were more modern.
Hudson and Ruby carried extra gas tanks and made one in-flight refueling each. Scott carried no extra gas and had two in-flight refuelings.
1st Lt. James E. Colson of Middleboro, Ky., tried to make it with no refueling. He got as far as Pittsburgh, Pa.
Of the other four unable to complete the flight, one dropped out in California, two in Kansas and one at Sedalia, Mo.

Robert Ray Scott was born at Des Moines, Iowa, 1 November 1920. He was the first of two children of Ray Scott, a railroad worker, and Elva M. Scott. He graduated from North High School in Des Moines, January 1939. He studied aeronautical engineering at the University of Iowa for two years before he enlisted as an Aviation Cadet in the U.S. Army Air Corps, 15 August 1941. Scott was 5 feet, 7 inches (1.70 meters) tall and weighed 144 pounds (65.3 kilograms). He was trained as a pilot and and was commissioned as a Second Lieutenant, 16 March 1942. He was assigned as an instructor pilot in California, and was promoted to 1st Lieutenant 15 December 1942.
Scott was transferred to the 426th Night Fighter Squadron, 14th Air Force, flying the Northrop P-61 Black Widow in India and China. He was promoted to captain, 3 May 1944, and to major, 16 August 1945. Major Scott was credited with shooting down two enemy aircraft. He was awarded the Distinguished Flying Cross and the Air Medal.
Following World War II, Major Scott returned to the University of Iowa to complete his bachelor’s degree. He also earned two master’s degrees.
In 1952 he graduated from the Air Force test pilot school at Edwards Air Force Base, then served as a project pilot on the North American F-86D all-weather interceptor. Later he was a project officer at Edwards AFB on the Republic F-105 Thunderchief Mach 2 fighter-bomber.
Scott flew the North American Aviation F-86F Sabre during the Korean War. From January to July 1953, he flew 117 combat missions. From 1953 to 1956, Lieutenant Colonel Scott commanded the 405th Fighter Bomber Wing, Tactical Air Command, at Langley Air force base, Virginia.
Scott was promoted to the rank of Colonel in 1960.
During the Vietnam War, Colonel Scott commanded the 355th Tactical Fighter Wing, flying 134 combat missions in the Republic F-105 Thunderchief. On 26 March 1967 he shot down an enemy MiG-17 fighter near Hanoi with the 20 mm M61 Vulcan cannon of his F-105D-6-RE, 59-1772, making him only the second Air Force pilot with air combat victories in both World War II and Vietnam.
Colonel Scott’s final commanding was the 832nd Air Division, 12th Air Force, at Cannon Air Force Base, New Mexico. He retired 1 September 1970 after 29 years of military service.
Colonel Robert Ray Scott flew 305 combat missions in three wars.During his Air Force career, Colonel Scott was awarded four Silver Star medals, three Legion of Merit medals, six Distinguished Flying Crosses and 16 Air Medals. He died at Tehachapi, California, 3 October 2006 at the age of 86 years. He is buried at the Arlington National Cemetery.
The Republic F-84F Thunderstreak was an improved, swept-wing version of the straight-wing F-84 Thunderjet fighter bomber. The first production Thunderstreak, 51-1346, flew for the first time, 22 May 1952, with company test pilot Russell M. (Rusty”) Roth in the cockpit. The F-84F was 43 feet, 4¾ inches (13.227 meters) long with a wingspan of 33 feet, 7¼ inches (10.243 meters) and overall height of 14 feet, 4¾ inches (4.388 meters). It had an empty weight if 14,014 pounds (6,357 kilograms) and maximum takeoff weight of 28,000 pounds (12,701 kilograms).
The initial F-84F-1-RE aircraft were powered by a Wright J65-W-1 turbojet, a license-built variant of the British Armstrong Siddely Sapphire. Later versions used Wright J65-W-3 and J65-W-7, or Buick J65-B-3 or J65-B-7 engines. The J65-B-3 was a single-shaft axial-flow turbojet with a 13-stage compressor section and 2-stage turbine. It produced 7,200 pounds of thrust (32.03 kilonewtons) at 8,200 r.p.m. The J65-B-3 was 9 feet, 7.0 inches (2.921 meters) long, 3 feet, 1.5 inches (0.953 meters) in diameter, and weighed 2,696 pounds (1,223 kilograms).
The F-84F had a maximum speed of 695 miles per hour (1,118 kilometers per hour) at Sea Level, and 658 miles per hour (1,059 kilometers per hour) at 20,000 feet. The fighter bomber could climb at 8,200 feet per minute (41.7 meters per second). Its service ceiling was 46,000 feet (14,021 meters).
Armament consisted of six Browning .50-caliber (12.7 × 99 NATO) AN-M3 aircraft machine guns, with two mounted in the wings and four in the nose. Up to 6,000 pounds (2,722 kilograms) of bombs and rockets could be carried under the wings. A variable-yield Mark 7 tactical nuclear weapon could also be carried.
Between 1952 and 1957, 2,112 F-84F Thunderstreaks were built by Republic at Farmingdale, New York, and by General Motors at Kansas City, Kansas. The Thunderstreak served with the United States Air Force and Air National Guard until 1971.
11 February 1939: Barely two weeks after its first flight, First Lieutenant Benjamin Scovill (“Ben”) Kelsey, U.S. Army Air Corps, took the prototype Lockheed XP-38, 37-457, on a record-breaking transcontinental flight from March Field, Riverside, California, to Mitchel Field, Long Island, New York.
Lieutenant Kelsey departed March Field at 6:32 a.m., Pacific Standard Time, (9:32 a.m., Eastern) and flew to Amarillo, Texas for the first of two refueling stops. He arrived there at 12:22 p.m., EST, and remained on the ground for 22 minutes. The XP-38 took off at 12:44 p.m., EST, and Kelsey flew on to Wright Field, Dayton, Ohio. He landed there at 3:10 p.m. EST.
Kelsey was met by Major General H.H. Arnold, and it was decided to continue to New York. The XP-38 was airborne again at 3:28 p.m., EST, on the final leg of his transcontinental flight.
Kelsey was overhead Mitchel Field, New York at 4:55 p.m., Eastern Standard Time, but his landing was delayed by other airplanes in the traffic pattern.
On approach, the XP-38 was behind several slower training planes, so Lieutenant Kelsey throttled back the engines. When he tried to throttle up, the carburetor venturis iced and the engines would not accelerate, remaining at idle. The airplane crashed on a golf course short of the airport.
The total elapsed time was 7 hours, 45 minutes, 36 seconds but Kelsey’s actual flight time was 7 hours, 36 seconds. The prototype had averaged 340 miles per hour (547 kilometers per hour) and had reached 420 miles per hour (676 kilometers per hour) during the Wright Field-to-Mitchel Field segment.
Kelsey’s transcontinental flight failed to break the transcontinental speed record set two years earlier by Howard R. Hughes by 17 minutes, 11 seconds. It should be noted, however, that Hughes H-1 Racer flew non-stop from coast to coast, while the XP-38 required two time-consuming fuel stops.
The XP-38 was damaged beyond repair, but its performance on the transcontinental flight was so impressive that 13 YP-38s were ordered from Lockheed by the Air Corps.
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 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 two 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.
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.
5 February 1949: An Eastern Air Lines Lockheed L-749A Constellation, serial number 2610, N115A, flew from Los Angeles to LaGuardia Airport, New York, in 6 hours, 18 minutes, setting a new West-to-East transcontinental speed record for transport aircraft.
The Lockheed L-749A Constellation was a longer-range development of the L-649, with fuel capacity increased by 1,130 gallons (4,278 liters). It was operated by a flight crew of four, with two to four flight attendants. It could carry up to 81 passengers.
The airplane was 97 feet, 4 inches (29.667 meters) long with a wingspan of 123 feet (37.49 meters) and an overall height of 22 feet, 5 inches (6.833 meters). It had an empty weight of 56,590 pounds (25,668 kilograms) and maximum takeoff weight of 107,000 pounds (48,534.4 kilograms).
The L-749A was powered by four 3,347.662-cubic-inch-displacement (54.858 liter) air-cooled, supercharged, fuel-injected, Wright Aeronautical Division Cyclone 18 745C18BD1 (R-3350-75), two-row 18-cylinder radial engines with a compression ratio of 6.5:1. This engine, also known as the Duplex-Cyclone, featured “jet stacks” which converted the piston engines’ exhaust to usable jet thrust, adding about 15 miles per hour (24 kilometers per hour) to the airplane’s speed. They had a normal power rating of 2,100 horsepower at 2,400 r.p.m., and 2,500 horsepower at 2,800 r.p.m. for takeoff, (five minute limit). The engines drove 15 foot, 2 inch (4.623 meter) diameter, three-bladed Hamilton Standard Hydromatic 43E60 constant-speed propellers through a 0.4375:1 gear reduction. The 745C18BD1 was 6 feet, 6.52 inches (1.994 meters) long, 4 feet, 7.62 inches (1.413 meters) in diameter and weighed 2,915 pounds (1,322 kilograms).
The L-749 had a cruise speed of 345 miles per hour (555.22 kilometers per hour) and a range of 4,995 miles (8,038.7 kilometers). Its service ceiling was 24,100 feet (7,346 meters).
N115A was leased to California Hawaiian Airlines, 1961–1962. In 1968 it was withdrawn from service and was scrapped in 1981.
