24 July 1936: On her 39th birthday, at the Union Air Terminal, Burbank, California, Amelia Earhart accepted delivery of her new Lockheed Electra 10E Special, registered NR16020.

$80,000 to buy the Electra was provided by the Purdue Research Foundation from donations made by several individuals. George Palmer Putnam, Amelia’s husband, made the arrangements to order the airplane and in March 1936 gave Lockheed the authorization to proceed, with delivery requested in June.

The Electra Model 10 was manufactured by the Lockheed Aircraft Company at Burbank, California. It was an all-metal, twin-engine, low-wing monoplane with retractable landing gear, designed as a small, medium-range airliner. In the standard configuration it carried a crew of 2 and up to 10 passengers. The Model 10 was produced in five variants with a total of 149 airplanes built between August 1934 and July 1941. Lockheed built fifteen Model 10Es. Earhart’s was serial number 1055.

Earhart’s Electra was equipped with a Western Electric Model 13C radio transmitter and Model 20B receiver for radio communication. It used a Sperry GyroPilot gyroscopic automatic pilot. Additional modifications included four auxiliary fuel tanks in the passenger compartment, a navigator’s station to the rear of that, elimination of passenger windows, installation of the autopilot, navigation equipment and additional batteries. These modifications varied from the standard airplane enough that it was restricted to carrying only members of required flight crew. This was denoted by the letter “R” in the airplane’s registration.

The Electra was not ready until mid-July. Earhart first flew the new airplane on 21 July with Lockheed test pilot Elmer C. McLeod.

The Electra 10E was 38 feet, 7 inches (11.760 meters) long with a wingspan of 55 feet (16.764 meters) and overall height of 10 feet, 1 inch (3.074 meters). The standard Model 10 had and empty weight of 6,454 pounds (2,927.5 kilograms) and a gross weight of 10,500 pounds (4,762.7 kilograms). NR16020 had an empty weight of 7,265 pounds (3295.4 kilograms). Lockheed’s performance data was calculated using 16,500 pounds (7,484.3 kilograms) as the Maximum Takeoff Weight.

NR16020 had a total fuel capacity of 1,151 gallons (4,357 liters) in ten tanks in the wings and fuselage. 80 gallons (302.8 liters) of lubricating oil for the engines was carried in four tanks.

Earhart’s Electra 10E Special was powered by two air-cooled, supercharged, 1,343.804-cubic-inch-displacement (22.021 liter) Pratt & Whitney Wasp S3H1 nine-cylinder radial engines, with a compression ratio of 6:1. These engines used a single-stage centrifugal supercharger and were rated at 550 horsepower at 2,200 r.p.m. at 5,000 feet (1,524 meters) and 600 horsepower at 2,250 r.p.m. for take off. The direct-drive engines turned 9 foot, 7/8-inch (3.010 meters) diameter, two-bladed, Hamilton Standard variable-pitch, constant-speed propellers. The Wasp S3H1 is 4 feet, 3.60 inches (1.311 meters) in diameter and 3 feet, 7.01 inches (1.093 meters) long. It weighed 865 pounds (392 kilograms).

The maximum speed for the Model 10E Special at Sea Level and maximum takeoff weight was 177 miles per hour (285 kilometers per hour), a reduction of 25 miles per hour (40 kilometers per hour) over the standard airplane. The maximum range was calculated to be 4,500 miles (7,242 kilometers)

24 July 1897: Amelia Mary Earhart was born at Atchison, Kansas. She was the older of two daughters of Edwin Stanton Earhart, an attorney, and Amelia Otis Earhart.

Amelia attended Hyde Park School in Chicago, Illinois, graduating in 1916. In 1917, she trained as a nurse’s aide with the Red Cross. While helping victims of the Spanish Flu epidemic, she herself contracted the disease and was hospitalized for approximately two months. In 1919 Earhart entered Columbia University studying medicine, but left after about one year.

Amelia first rode in an airplane at Long Beach, California with pilot Frank Monroe Hawks, 28 December 1920. The ten-minute flight began her life long pursuit of aviation. She trained under Mary Anita Snook at Kinner Field near Long Beach, California.

Earhart was the sixteenth woman to become a licensed pilot when she received her certificate from the National Aeronautic Association on behalf of the Fédération Aéronautique Internationale (FAI) on 16 May 1923.

Amelia Earhart became the first woman to cross the Atlantic Ocean by air when she accompanied pilot Wilmer Lower Stultz and mechanic Louis Edward Gordon as a passenger aboard the Fokker F.VIIb/3m, NX4204, Friendship, 17–18 June 1928. The orange and gold, float-equipped, three-engine monoplane had departed from Trepassey Harbor, Newfoundland and Labrador, Canada, and arrived at Burry Port on the southwest coast of Wales, 20 hours, 40 minutes later. (Although Earhart was a pilot with approximately 500 hours of flight experience at this time, she did not serve as one of the pilots on this flight.)

On 1 May 1930, the Aeronautics Branch, Department of Commerce, issued Transport Pilot’s License No. 5716 to Amelia Mary Earhart. On 25 June 1930, the newly-licensed commercial pilot set a Fédération Aéronautique Internationale World Record for Speed Over a a Closed Circuit of 100 Kilometers With a 500 Kilogram Payload, averaging 275.90 kilometers per hour (171.44 miles per hour) with her Lockheed Vega.¹ That same day, she set another World Record for Speed Over 100 Kilometers of 281.47 kilometers per hour (174.90 miles per hour).² About two weeks later, Earhart increased her Vega’s speed across a shorter, 3 kilometer course, with an average 291.55 kilometers per hour (181.16 miles per hour).³

Amelia Earhart was a charter member of The Ninety-Nines, Inc., an international organization of licensed women pilots. She served as their first president, 1931–1933.

On 7 February 1931, Miss Earhart married George Palmer Putnam in a civil ceremony at Noank, Connecticut. Judge Arthur P. Anderson presided. In a written prenuptial agreement, Miss Earhart expressed serious misgivings about marrying Mr. Putnam, and wrote, “. . . I shall not hold you to any medieval code of faithfulness to me nor shall I consider myself bound to you similarly.”

Earhart had her own line of women’s fashions, made from wrinkle-free fabrics. She modeled for her own advertisements. In November 1931, Earhart was the subject of a series of photographs by Edward Steichen for Vogue, an American fashion magazine.

At Warrington, Pennsylvania, 8 April 1931, Amelia Earhart (now, Mrs. George P. Putnam) flew a Pitcairn PCA-2 autogyro to an altitude of 5,613 meters (18,415 feet). Although a sealed barograph was sent to the National Aeronautic Association for certification of a record, NAA does not presently have any documentation that the record was actually homologated.

On the night of 20–21 May 1932, Amelia Earhart flew her Vega 5B from Harbor Grace, Newfoundland, solo and non-stop, across the Atlantic Ocean to Culmore, Northern Ireland. The distance flown was 2,026 miles (3,260.5 kilometers). Her elapsed time was 14 hours, 56 minutes. On 18 July 1932, Earhart was awarded the Distinguished Flying Cross by President Herbert Hoover, for “extraordinary achievement in aviation.”

Earhart next flew her Vega non-stop from Los Angeles, California, to New York City, New York, 24–25 August 1932, setting an FAI record for distance without landing of 3,939.25 kilometers (2,447.74 miles).⁴ Her Lockheed Vega 5B, which she called her “little red bus,” is displayed in the Barron Hilton Pioneers of Flight Gallery of the Smithsonian Institution National Air and Space Museum, Washington, D.C.

At 4:40 p.m., local time, 11 January 1935, Amelia Earhart departed Wheeler Field on the island of Oahu, Territory of Hawaii, for Oakland Municipal Airport at Oakland, California, in her Lockheed Vega 5C Special, NR965Y. She arrived 18 hours, 15 minutes later. Earhart was the first person to fly solo from Hawaii to the Mainland.

Amelia Earhart is best known for her attempt to fly around the world with navigator Frederick J. Noonan in her Lockheed Electra 10E Special, NR16020, in 1937. She disappeared while enroute from Lae, Territory of New Guinea, to Howland Island in the Central Pacific, 2 July 1937. The massive search effort for her and her navigator failed, and what happened to her and Noonan remains a mystery.

2 July 1937: At approximately 10:00 a.m., local time, Amelia Earhart and Fred Noonan departed Lae, Territory of New Guinea, aboard their Lockheed Electra 10E Special, NR16020, enroute to Howland Island, 2,243 nautical miles (2,581 statute miles/4,154 kilometers) east-northeast across the South Pacific Ocean. The airplane was loaded with 1,100 gallons (4,164 liters) of gasoline, sufficient for 24 to 27 hours of flight.

They were never seen again.

1 July 1937: Amelia Earhart and Fred Noonan are delayed another day at Lae, Territory of New Guniea.

“July 1st. ‘Denmark’s a prison,’ and Lae, attractive and unusual as it is, appears to two flyers just as confining, as the Electra is poised for our longest hop, the 2,556 miles to Howland Island in mid-Pacific. The monoplane is weighted with gasoline and oil to capacity. However, a wind blowing the wrong way and threatening clouds conspired to keep her on the ground today. In addition, Fred Noonan has been unable, because of radio difficulties, to set his chronometers. Any lack of knowledge of their fastness and slowness would defeat the accuracy of celestial navigation. Howland is such a small spot in the Pacific that every aid to locating it must be available. Fred and I have worked very hard in the last two days repacking the plane and eliminating everything unessential. We have even discarded as much personal property as we can decently get along without and henceforth propose to travel lighter than ever before. All Fred has is a small tin case which he picked up in Africa. I noted it still rattles, so it cannot be packed very full. Despite our restlessness and disappointment in not getting off this morning, we still retained enough enthusiasm to do some tame exploring of the near-by country.”

29 June 1937: Leg 28. Amelia Earhart and Fred Noonan fly the Lockheed Electra 10E, NR16020, from Darwin, Northern Territory, Australia, to Lae, Territory of New Guinea.

“Lae, New Guinea, June 30th. After a flight of seven hours and forty-three minutes from Port Darwin, Australia, against head winds as usual, my Electra now rests on the shores of the Pacific. Beyond the Gulf of Huon the waters stretch into the distance. Somewhere beyond the horizon lies California. Twenty-two thousand miles have been covered so far. There are 7,000 to go.

“From Darwin we held a little north of east, cutting across the Wellington Hills on the northern coast of Arnhem Land, which is the topmost region of Australia’s Northern Territory. The distance to Lae was about 1,200 miles. Perhaps two-thirds of it was over water, the Arafura Sea, Torres Strait and the Gulf of Papua.

“Midway to New Guinea the sea is spotted with freakish islands, stony fingers pointing towards the sky sometimes for hundreds of feet. We had been told the clouds often hang low over this region and it was better to climb above its hazardous minarets than to run the risks of dodging them should we lay our course close to the surface. Then, too, a high mountain range stretches the length of New Guinea from northwest to southeast. Port Moresby was on the nearer side, but it was necessary to clamber over the divide to reach Lae situated on the low land of the eastern shore. As the journey progressed we gradually increased our altitude to more than 11,000 feet to surmount the lower clouds encountered. Even at that, above us towered cumulus turrets, mushrooming miraculously and cast into endless designs by the lights and shadows of the lowering sun. It was a fairy-story sky country, peopled with grotesque cloud creatures who eyed us with ancient wisdom as we threaded our way through its shining white valleys. But the mountains of cloud were only dank gray mist when we barged into them, that was healthier than playing hide-and-seek with unknown mountains of terra firma below. Finally, when dead reckoning indicated we had traveled far enough, we let down gingerly. The thinning clouds obligingly withdrew and we found ourselves where we should be, on the western flanks of the range with the coastline soon blow us. Working along it, we found Lae and sat down. We were thankful we had been able to make our way successfully over those remote regions of sea and jungle – strangers in a strange land.”
