11 July 1935: At 4:31 a.m., Eastern Daylight Time, (08:31 UTC) Laura Houghtaling Ingalls took off from Floyd Bennett Field, Brooklyn, New York, and flew non-stop across the North American continent to the Union Air Terminal at Burbank, California. She landed there at 7:51 p.m., Pacific Daylight Time (02:51 UTC, 12 July). The elapsed time of her non-stop transcontinental flight was 18 hours, 19 minutes, 30 seconds.

After departing Floyd Bennett Field, Ingalls flew along a commercial airway defined by radio beacons. Her route of flight was from Brooklyn, New York, to Pittsburgh, Pennsylvania—Columbus, Ohio—Indianapolis, Indiana—Kansas City, Missouri—Albuquerque, New Mexico—Burbank, California. This was only the third time that a non-stop transcontinental flight had been accomplished.

The Los Angeles Times reported:

MISS INGALLS SETS RECORD IN AIR DASH

Nation Spanned Nonstop

First Woman Ever to Cross from East Without Halt Also Slashes Time.

     Hatless and with her brown curls flying, diminutive Laura Ingalls, 30-year-old aviatrix, set her black-cowled monoplane down at Union Air Terminal, Burbank, at 7:51 o’clock last night and became the first woman pilot ever to span the American continent in an East-to-West nonstop flight.

Taking off from Floyd Bennett Airport, New York, at 4:31:30 a.m., she completed the Atlantic-to-Pacific hop in eighteen hours nineteen minutes and thirty seconds, establishing a women’s East-to-West record. She was timed in by Ted Raycraft, National Aeronautic Association representative.

     Miss Ingalls failed, however, to break Amelia Earhart’s transcontinental mark of seventeen hours seven minutes and thirty seconds, set in 1933 in a Pacific-to-Atlantic hop. Winds are more favorable for flights starting from the West.

TELLS OF ORDEAL

     With powerful floodlights playing on he low-winged Lockheed plane, Miss Ingalls circled the field once before landing.

     “Boy, what a long ride!” she exclaimed as she climbed from the cockpit. “It was an ordeal and I’m glad I’m here.”

     She immediately began plans, however, for an onslaught on Miss Earhart’s West-to-East record and said she contemplated a return nonstop flight as quickly as her ship can be overhauled and placed in order.

DISAPPOINTED AT TIME

     The aviatrix said she had hoped to make the flight in fifteen hours and expressed disappointment that she was unable to do so.

     The East-to-West nonstop record for men was established by Jimmie Doolittle in slightly more than thirteen hours.

     Miss Ingalls said she encountered strong head winds most of the way and ran into an electrical storm over Winslow, Ariz., shortly after 5 p.m., which slowed her down.

    She followed a TWA transport route most of the way and depended on the TWA radio beam for her directions. Her ship is equipped with a radio receiving set, radio compass, Sperry automatic pilot, retractable landing gear and landing wing flaps.

     Miss Ingalls said she took off from the New York airport with a capacity load of 600 gallons of gasoline, enough to have carried her 3,000 miles.

     She experienced some difficulty in gaining altitude with the heavy load and was forced to slow down at the start when she was unable to raise the retractable landing gear.

Her speed at times, however, exceeded 200 miles an hour, she said. The ship has a top speed of about 240 miles an hour.

     After leaving New York, her ship was unsighted until she passed over the TWA airport at Winslow about 5:15 p.m.

TAXIES PLANE TO HANGAR

     After landing at Burbank and removing her heavy shoes and flying togs, she taxied the plane to the Western Air Express hangar and gave orders for its care. She then went to the California Hotel in Burbank, where she will reside while here.

     The flyer took up airplanes at Roosevelt Field in New York six years ago because she was “tired of vaudeville and wanted some excitement.”

SIX-YEAR RECORD

     In six years she set the first women’s east-west transcontinental record. She has looped 980 times for a women’s record. She has barrel-rolled 714 times for a world’s record. She has captured third place in the Chicago-Dixie air derby. She has solo hopped 17,000 miles around South America with no accidents.She has been chosen outstanding woman flyer for 1934 by International League of Aviators.

Laura Houghtaling Ingalls’ Lockheed Orion 9D Special, NR14222. (San Diego Air and Space Museum Archives)

Ingall’s airplane was a single-engine Lockheed Model 9D Orion Special, registration NR14222, which she had named Auto da Fé. ¹ Ingalls had taken delivery of the Orion at the Lockheed Aircraft Company, Burbank, California, 1 February 1935. Contemporary newspaper reports said that the “Black Mystery Ship” cost $45,000.

The Lockheed Model 9 Orion was a single-engine, low-wing monoplane, designed in 1931 by Gerard Freebairn Vultee for airline use. It was capable of carrying six passengers in an enclosed cabin. The Orion was the first commercial airliner with retractable landing gear. It was faster than any military airplane in service at the beginning of the decade. Like other Lockheed aircraft of the time, it was constructed of strong, light-weight, molded wood, but the Orion would be Lockheed’s last wooden airplane.

Auto da Fé was powered by an air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S1D1 nine-cylinder radial engine. The engine had a compression ratio of 6:1 and was rated 525 horsepower at 2,200 r.p.m. The S1D1 was a direct-drive engine, which turned a two-bladed Hamilton Standard variable-pitch, constant-speed propeller. The Wasp S1D1 was 4 feet, 3.438 inches (1.307 meters) in diameter, 3 feet, 6.625 inches (1.083 meters) long and weighed 763 pounds (346 kilograms). The engine was enclosed by a N.A.C.A. cowling.

The cruise speed of the Orion was 205 miles per hour (330 kilometers per hour) and the maximum speed was 220 miles per hour (354 kilometers per hour) at Sea Level. It had a range of 750 miles (1,159 kilometers) in standard configuration. The service ceiling was 22,000 feet (6,705 meters).

Ingall’s airplane had a fuel capacity of 630 gallons (2,385 liters) of gasoline and 40 gallons (151 liters) of engine oil. NR14222 was equipped with a Sperry Gyro Pilot and a Westport radio compass and receiver for navigation.

The Greek lower-case letter zeta (the astronomical symbol for the planet Jupiter) was painted on each side of the airplane under the cockpit rails. Ingalls had the same symbol on several of her airplanes. A source suggests that it was used as a stylized representation of her initials, “L.I.” (Her Lockheed Air Express carried the astronomical symbol for the constellation Sagittarius, which was Ingalls’ astrological sign.)

In 1937, NR14222 was sold to Rudolf Wolf, Inc., a burlap company in New York. It was then transferred to Fuerzas Aéreas de la República Española (FARE), the air arm of the Spanish Republican forces during the Spanish Civil War. What happened to the Lockheed Orion after that is not known.

Laura Houghtaling Ingalls was born at Brooklyn, New York, 14 December 1893. She was the first of two children of Francis Abbott Ingalls, a cotton goods merchant, and Laura McAlister Houghtaling Ingalls.

Laura Ingalls, 1920

Miss Ingalls lived in France prior to World War I, and returned there as a relief worker following the War. In 1920, she lived with her family in Tuxedo Park, New York, and was employed as a stenographer.

Laura Ingalls began flight training at Roosevelt Field, Long Island, New York, and completed her first solo flight on 23 December 1928.  In June 1929, she began training for a commercial pilot certificate at the Universal Flying School, Lambert Field, St. Louis Missouri.

Woman Pilot Finishes Studies

     Miss Laura Ingalls, who recently received a limited commercial license, has completed her studies at the Universal Flying School and is taking the examination for a transport license under Inspector Fox. Miss Ingalls’ home is in New York, where she is said to have received several offers of work as a pilot.

St. Louis Post-Dispatch, Vol. 82, No. 212, Sunday, 6 April 1930, Page 6-I, Column 1

Ingalls qualified for her limited transport license, 12 April 1930. (After qualifying for an F.C.C. radio-telephone operator license in 1934, her restricted transport license was upgraded to Scheduled Airline Transport Pilot, 26 January 1935.) Her pilot certificate number was 9330.

Laura Ingalls first gained public attention when she performed 344 consecutive loops with a de Havilland DH.60G Gipsy Moth NR9720 (c/n 885), at St. Louis, 4 May 1930. Three weeks later, she increased the number of loops to 980. On August 13, she completed 714 consecutive barrel rolls in the same airplane. (At the time, the airplane was a demonstrator for the Moth Aircraft Corporation, Lowell, Massachusetts, which was licensed by de Havilland to produce the DH.60 in the United States. Kits were built in England, then assembled in Massachusetts. Miss Ingalls later purchased the airplane, 23 June 1930.)

Laura Houghtaling Ingalls rests against the lower wing of her de Havilland DH.60G Gipsy Moth while its engine idles, October 1930. The forward cockpit is covered.

Miss Ingalls was the first woman to fly across the United States from East to West. In 5 October 1930, she flew NR9720 from Roosevelt Field, Westbury, Long Island, new York, to the Grand Central Air Terminal at Glendale, California, arriving 9 October. The flight required nine fuel stops, and took 30 hours and 27 minutes over four days.

Between 28 February and 25 April 1934, Laura Ingalls flew a Lockheed Model 3 Air Express, NR974Y, on a 17,000-mile (27,400 kilometers) solo flight around South America and over the Andes mountain range.

Laura Ingalls was awarded the Harmon Aviatrix Trophy for 1934.

Ingalls flew her Orion in the 1936 Bendix Trophy Race, finishing in second place behind Louise Thaden, with an elapsed time of 15 hours, 39 minutes.

Miss Ingalls bought a Ryan ST-A low-wing monoplane, NC18901 (c/n 179), which was powered by a 125 horsepower Menasco C4 Pirate inverted 4-cylinder engine. The Ryan ST was developed into the Ryan PT-16–22 military trainers of World War II.

In 1939, Laura Ingalls dropped political leaflets during a 2-hour flight over Washington, D.C. On landing, she was met by representatives of the Civil Aeronautics Administration. Her pilot’s license was suspended by the C.A.A. for violating the airspace surrounding The White House. Some sources indicate that the license was later revoked.

After the United States entered World War II, Miss Ingalls was arrested for acting as an unregistered paid agent of Nazi Germany. At trial, she was convicted. She served 1 year, 7 months, 15 days in prison. (Ingalls was initially incarcerated at the federal prison in Washington, D.C., but after having been severely beaten by other prisoners, she was transferred to the womens’ prison in Alderson, West Virginia.)

Laura Houghtaining Ingalls died at her home in Burbank, California, 10 January 1967, at the age of 73 years. Her ashes were interred at Wiltwyck Cemetery, Kingston, New York.

Joseph Sadi-Lecointe (11 July 1891–15 July 1944)

Joseph Sadi-Lecointe, 1924

Joseph Sadi-Lecointe was born 11 July 1891 at Saint-Germain-sur-Bresle, Departement de la Somme, Picardie, France.

Sadi-Lecointe was employed as an aircraft welder. On 30 January 1910, without any instruction, he took off from Issy-les-Moulineaux in a monoplane designed by George and Gendre Zénith. The Aero Club de France awarded him its license number 431 on 10 February 1911.

He joined the Service Aéronautique (the original form of the French Air Force) as a mechanic in October 1912, and was designated pilote militaire nº375, 20 September 1913.

Sadi-Lecointe was promoted to sergeant 6 July 1914. He served as a pilot during World War I, flying the Blériot XI-2 with l’escadrille BL 10 from 1 August 1914 to 6 March 1915. After serving five weeks with the RGA, Sergent Sadi-Lecointe was transferred to N 48, flying the Nieuport X. He was promoted to Adjutant, a warrant officer rank, 17 April 1915. On 23 November 1915 became a flight instructor at l’Ecole de Pilotage d’Avord. Sadi-Lacointe was promoted to sous-lieutenant in October 1916. On 17 September 1917 he was assigned as a test pilot at BlériotSociété Pour L’Aviation et ses Dérivés, where he worked on the development of the famous SPAD S.XIII C.1 fighter.

10 July 1982: The first scheduled jet airliner flown in the United States with an all-female crew was Piedmont Airlines’ Flight 328 from Norfolk, Virginia, to Newark, New Jersey. The airliner was a Boeing 737. Captain Cheryl Faye Peters and First Officer Rebecca Rose Schroeder were on the flight deck. The Flight Attendants were Paula Lanier, Dolly Wenat and Cindy Perry. The duration of the flight was 1 hour, 1 minute.

Cheryl Faye Peters, 1963 (The Colonel)

Cheryl Faye Peters was born in 1945 in Roanoke, Virginia. She is the daughter of Lowell Lewis Peters and Virginia Crumpacker Peters. She attended William Fleming High School, graduating in 1963. A member of the school’s student government, Miss Peters served as secretary-treasurer of the senior class. She was a cheerleader, played basketball and volleyball, and was the school’s 24th Homecoming Queen.

After high school, Miss Peters began taking flying lessons. She also rode motorcycles and learned to skydive.

In 1965, she went to work for Eastern Air Lines as a flight attendant based at Miami, Florida. The following year, Eastern’s machinists’ union went on strike and Miss Peters was furloughed. With time available, she continued her flight training, earning a private, then commercial pilot’s license with ratings in both single-engine and multi-engine airplanes. She also earned a flight instructor’s certificate.

In December 1967, Miss Peters married Mr. James Bowers Ritchie III, a law student, in Roanoke.

Following the airline strike, Ms. Peters (Mrs. Ritchie) returned to work at Eastern, but also worked as a commercial pilot and flight instructor. By 1974 she had flown more than 2,000 hours.

In 1974, Cheryl Peters Ritchie applied to Piedmont Airlines as a pilot. After passing her employment interview, in which she was required to fly a simulator in a “Hydraulics OFF” mode to evaluate her strength, she became the first woman to be hired as a pilot by Piedmont.

Ms. Peters completed initial flight training with the company on her 29th birthday, and was then assigned as a first officer on the twin-engine Nihon YS-11 turboprop. Later, she transitioned to the twin-jet Boeing 737.

The airliner flown by Captain Peters and First Officer Schroeder was a Boeing 737-201A, serial number 22443, with U.S. registration N786N. It had first flown exactly one year earlier, 10 July 1981, and was delivered to Piedmont Airlines on 29 July 1981. The 737 was christened Roanoke Valley Pacemaker.

The Boeing 737-200 series were short- to medium-range, narrow body, twin-engine civil transports. The -200 first flew 8 August 1967. It had a flight crew of two and could carry a maximum of 136 passengers.

The 737-200 is 100 feet, 2 inches (30.531 meters) long with a wingspan of 93 feet, 0 inches (28.346 meters) and overall height of 36 feet, 10 inches (11.227 meters). Flight 243’s actual takeoff weight was 93,133 pounds (42,224 kilograms). (Its maximum certificated takeoff weight was 100,000 pounds (45,359 kilograms).

The airliner was powered by two Pratt & Whitney JT8D-9A low-bypass turbofan engines producing 14,500 pounds of thrust, each. The 737-200 had a cruise speed of 0.74 Mach (489 miles per hour, 787 kilometers per hour) and a maximum speed of 0.82 Mach (542 miles per hour/872 kilometers per hour). The service ceiling was 35,000 feet (10,668 meters).

1,010 Boeing 737–200s were built. The last one in service with an American airline was retired 21 March 2008.

10 July 1962: At 0835 GMT (4:35 a.m., EDT) the first communications relay satellite, Telstar 1, was launched into Earth orbit from Launch Complex 17B, Cape Canaveral Air Force Station, Florida. The launch vehicle was a three-stage liquid-fueled Delta rocket.

This was the first commercial space flight, sponsored by a consortium of communications companies and government organizations, including AT&T, Bell Labs, the BBC, NASA, and British and French postal services. The satellite was used to relay live television broadcasts across the Atlantic Ocean. This had never previously been possible.

Telstar weighed 171 pounds (77.5 kilograms). Its weight and size were restricted by the availability of launch vehicles. The satellite was placed in an elliptical orbit, varying from 591 miles (952 kilometers) to 3,686 miles (5,933 kilometers), and inclined at about a 45° angle to Earth’s Equator. The orbital period was 2 hours, 37 minutes. The properties of Telstar’s orbit restricted its use to about 20 minutes during each pass.

In addition to its primary role as a communications relay satellite, Telstar also performed scientific experiments to study the Van Allen Belt.

The Delta was a three-stage expendable launch vehicle which was developed from the Douglas Aircraft Company’s SM-75 Thor intermediate-range ballistic missile.

Designated Thor DM-19, the first stage was 60.43 feet (18.42 meters) long and 8 feet (2.44 meters) in diameter. Fully fueled, the first stage had a gross weight of 108,770 pounds (49,337 kilograms). It was powered by a Rocketdyne LR-79-7 engine which burned liquid oxygen and RP-1 (a highly-refined kerosene rocket fuel) and produced 170,565 pounds of thrust (758.711 kilonewtons). This stage had a burn time of 2 minutes, 45 seconds.

The second stage was an Aerojet General Corporation-built Delta 104. It was 19 feet, 3 inches (5.88 meters) long with a maximum diameter of 4 feet, 6 inches (1.40 meters). The second stage had a gross weight of 9,859 pounds (4,472 kilograms). It used an Aerojet AJ10-104 rocket engine which burned a hypergolic  mixture of nitric acid and UDMH. The second stage produced 7,890 pounds of thrust (35.096 kilonewtons) and burned for 4 minutes, 38 seconds.

The third stage was an Allegany Ballistics Laboratory Altair 1. It was 6 feet long, 1 foot, 6 inches in diameter and had a gross weight of 524 pounds (238 kilograms). This stage used a solid-fuel Thiokol X-248 rocket engine, producing 2,799 pounds of thrust (12.451 kilonewtons). Its burn time was 4 minutes, 16 seconds.

The three stages of the Delta rocket accelerated the Telstar satellite to 14,688 miles per hour for orbital insertion.

The day prior to launch, the United States detonated a 1.45 megaton thermonuclear warhead at an altitude of 248 miles (400 kilometers), near Johnston Island in the Pacific Ocean. (Operation Dominic-Fishbowl Starfish Prime). Between 21 October 1961 and 1 November 1962, the Soviet Union detonated five nuclear warheads in space (Project K), at altitudes ranging from 59 to 300 kilometers (37–186 miles) over a test range in Khazakhstan. High energy electrons from these tests were trapped in the Earth’s radiation belts. This damaged the satellite’s circuitry and it went out of service in December 1962. ¹

Engineers were able to work around the damage and restore service by January 1963, but Telstar 1 failed permanently 21 February 1963.

Telstar is still in Earth orbit.

10 July 1943

U.S. Paratroopers in North Africa prepare to board an 8th Air Force Douglas C-47-DL Skytrain, 41-18341, for Operation Husky, the invasion of Sicily, 9 July 1943.

10 July 1943: Following the defeat of Germany and Italy by the Allies in North Africa, the next phase of the war plan was the invasion of Sicily. This began with the largest airborne assault ever attempted by U.S. and British paratroopers up to that time.

Shortly after midnight, a Regimental Combat Team (RCT) under command of Colonel James M. Gavin, United States Army, and consisting of the 505th Parachute Infantry Regiment with the 3rd Battalion, 504th Parachute Infantry Regiment, dropped out of a moonlit sky around Gela on the southern shore of the island and achieved reasonable success. 226 C-47 Skytrains of the 52d Troop Carrier Wing dropped 3,405 U.S. paratroopers. A second airborne assault by the remaining 1,900 paratroopers of the 504th PIR  was carried into battle by 144 C-47s from the 52d TCW.

The British Army 1st Air Landing Brigade under Brigadier Philip Hicks arrived on gliders to capture landing zones in the interior of the island.

As the Allied formation of 144 Douglas C-47 Skytrain transports approached the Sicilian shoreline, ships of the invasion force mistook them for enemy aircraft and opened fire. 22 C-47s were shot down and many others damaged. 83 men were killed and 318 wounded.

As a result of the friendly fire incident, the airborne assault was widely scattered, missing assigned drop zones and objectives. However, small groups of airborne troopers acting on their own initiative attacked targets of opportunity and kept the island’s defenders off balance.

The British glider assault, Operation Ladbroke, consisted of 8 Airspeed Horsa and 136 American Waco CG-4 transport gliders. Only 12 of these landed at their targets. At least 65 went into the sea with the loss of over 250 British soldiers.

Operation Fustian was the airborne assault by the 1st Parachute Brigade under the command of Brigadier Gerald Lathbury was carried by 105 C-47s, 11 Armstrong Whitworth Ablemarle paratroop transports, 11 Horsa and 8 Waco gliders. Approximately 40 of these were shot down by Allied and Axis anti-aircraft fire and several were lost to mid-air collisions. Many transports were badly damaged and had so many wounded paratroops that they aborted the mission and returned to North Africa.

Despite significant problems, the airborne troops kept the island’s defenders off guard and had a “positive effect” on the outcome of the invasion.
