4–5 September 1936: At 6:50 p.m., British Summer Time, Beryl Markham departed RAF Abingdon, Oxfordshire, England, aboard a turquoise blue and silver Percival P.10 Vega Gull, registration VP-KCC. Her intended destination was New York City, across the Atlantic Ocean in America.

The airplane flown by Mrs. Markham, serial number K.34, was brand-new, built for John Evans Carberry (formerly, 10th Baron Carbery) for his entry in The Schlesinger air race from London, England, to Johannesburg, South Africa. He loaned the airplane to her for the transatlantic flight on condition that she would return it to England by mid-September, in time for the start of the race.

Designed by Edgar Percival and built by Percival Aircraft Limited at Gravesend, the P.10 Vega Gull was a four-place, single engine monoplane with fixed landing gear. Known as the K-series, it was a development of the previous D-series Gull Six. The airplane was 25 feet, 6 inches (7.772 meters) long with a wingspan of 39 feet, 6 inches (12.040 meters) and height of 7 feet, 4 inches (2.235 meters). The standard airplane had an empty weight of 1,740 pounds (789.25 kilograms) and loaded weight of 3,250 pounds (1,474.2 kilograms). K.34, the airplane flown by Markham, carried two auxiliary fuel tanks in the passenger compartment, for a total capacity of 255 gallons (965.3 liters).

The Vega Gull was powered by an air-cooled, normally-aspirated, 9.186 liter (560.573-cubic-inch-displacement) de Havilland Gypsy Six I, an inverted inline six-cylinder overhead valve (OHV) engine. The engine had a compression ratio of 5.25:1. It was rated at 184 horsepower at 2,100 r.p.m., and  205 horsepower at 2,350 r.p.m. for takeoff. The direct-drive engine turned a two-bladed Ratier variable-pitch propeller. The Gypsy Six I weighed 432 pounds (196 kilograms).

The Vega Gull had a cruising speed of 150 miles per hour (241 kilometers per hour) and a maximum speed of 174 miles per hour (280 kilometers per hour). The service ceiling was 17,000 feet (5,181.6 meters). Estimated range with the auxiliary fuel tank was 3,800 miles (6,115.5 kilometers).

John Carberry was a resident of Colony and Protectorate of Kenya so the new airplane received the civil registration marking, VP-KCC. It was named The Messenger.

Beryl Markham was an experienced airplane pilot who had most recently been employed as Chief Pilot, Air Cruisers Limited, owned by a French financier, François Dupré. She was certified both as a pilot and an aircraft mechanic, and had recently had her pilot’s license endorsed for “All Types.”

Mrs. Markham and the airplane were ready for the solo transoceanic flight by 1 September, but were delayed by bad weather, with worse forecast. Captain Percival had recommended that she start from RAF Abingdon because its 1 mile runway (1.6 kilometers) would give the overweight airplane a longer takeoff run.

By the 4th, however, she was impatient with waiting and decided to takeoff regardless of the weather. She arrived at the airfield at about 5:00 p.m. Her takeoff was delayed while the runway was cleared of a wrecked bomber that had been overturned by the high winds.

Because of the high winds, the Vega Gull was airborne in just 600 yards (550 meters).

From the start, Markham encountered heavy rain, low clouds, fog, and gale force winds. Almost immediately, her carefully-prepared chart was blown out of a cockpit window. She flew most of the distance at an altitude of about 2,000 feet (610 meters). If she climbed higher, the rain turned to ice. If she flew lower she was in danger of the winds forcing her into the sea below. She had hoped to have the light of a nearly full moon as she crossed the Atlantic at night but the weather was so bad that she flew by reference to her instruments for the entire crossing.

During the transatlantic flight the Percival Vega Gull was sighted by several ships which reported her position. Although the airplane had a cruising speed of 150 miles per hour (241 kilometers per hour), because of the headwinds, Markham estimated her rate of advance at just 90 miles per hour (145 kilometers per hour). With the airplane running on fuel from the final tank, which should have lasted 11 hours, the gauge indicated that it was being consumed at a higher rate. She estimated her position as nearing Newfoundland but with rain, clouds and fog, she was only able to see brief views of the ocean below.

“The dawn broke through the clouds. The wind changed and I stopped being so silly. I wouldn’t have imagined that there was an expanse of desolation so big in the whole world as the waste of sky and water I saw go past me since I left Abingdon. . . It was fog, rain, sleet for hours on end. If I climbed it was sleet, if I dropped it was rain. If I skimmed the sea it was fog. I couldn’t see anything beyond my wingtips. . .

“That tank, on which I was banking my all, didn’t last eleven hours. It lasted nine hours and five minutes. . . I watched that tank getting emptier and emptier and still saw nothing but sea and clouds and mist. . . I could see nothing to save me. Good old Messenger was going to stop any moment and I said to myself, ‘If I’m going to go, now is the time to get ready for it.’ The only thing anywhere around was fog, great hefty banks of it. And then I saw the coast. The beautiful coast. I’ve never seen land so beautiful. . . But then the engine began to go ‘put, put, put.’

“. . . I knew then that I had to come down and made for the beach. I couldn’t land there; there was nothing but great big rocks and Messenger and I would have been dashed to pieces. I went inland.

“My engine was missing badly now. It was sheer agony to watch my petrol gauge . . . I peered around for a field to land on. I was still peering when the engine stopped.”

 Beryl Markham, quoted in Straight on Till Morningby Mary S. Lovell, St. Martin’s Press, New York, 1987, Chapter 9 at Pages 177–178.

The field turned out to be a peat bog at Baliene Cove on Cape Breton Island, Nova Scotia, Canada. The airplane nosed over in the soft surface. Beryl Markham struck her head and was briefly knocked unconscious. She soon climbed out of the damaged Vega Gull and was taken to a nearby farm where help soon arrived.

Beryl Markham did not reach her intended destination of New York City. But what she did accomplish was the first East-to-West solo crossing of the Atlantic Ocean by a woman. Although Amelia Earhart had flown solo across the Atlantic in her Lockheed Vega four years earlier, her crossing was West-to-East. Because of the prevailing weather patterns, the westerly crossing is considered much more difficult.

Beryl and The Messenger returned to England aboard the passenger liner RMS Queen Mary. Although the damage was repaired, it was not in time to compete in The Schlesinger. John Carberry sold VP-KCC to Dar-es-Salaam Airways. It was written off in Tanganyika in August 1937, and de-registered in March 1938.

Beryl Markham was a remarkable woman whose exploits are too great to touch on here. She wrote West with the Night, which was considered by author Ernest Hemingway to be “a bloody wonderful book.” She died at her home in Nairobi, Kenya, 3 August 1986, at the age of 83.

The rigid airship Graf Zeppelin, LZ 127, under the command of Dr. Hugo Eckener, departed Lakehurst Naval Air Station, New Jersey, 8 August 1929, heading east across the Atlantic Ocean on the first aerial circumnavigation by air. The flight was sponsored by publisher William Randolph Hearst, who had placed several correspondents aboard.

Graf Zeppelin was named after Ferdinand Adolf Heinrich August Graf von Zeppelin, a German general and count, the founder of the Zeppelin Airship Company. The airship was constructed of a lightweight metal structure covered by a fabric envelope. It was 776 feet (236.6 meters) long. Contained inside were 12 hydrogen-filled buoyancy tanks, fuel tanks, work spaces and crew quarters.

A gondola mounted underneath contained the flight deck, a sitting and dining room and ten passenger cabins. The LZ-127 was manned by a 36 person crew and could carry 24 passengers.

LZ-127was powered by five water-cooled, fuel injected 33.251 liter (2,029.1 cubic inches) Maybach VL-2 60° V-12 engines producing 570 horsepower at 1,600 r.p.m., each. Fuel was either gasoline or blau gas, a gaseous fuel similar to propane. The zeppelin’s maximum speed was 80 miles per hour (128 kilometers per hour).

After refueling at the Kasumigaura Naval Air Station, Tokyo, Japan, Graf Zeppelin started east across the Pacific Ocean on 23 August, enroute to Los Angeles, California. This leg crossed 5,998 miles (9,653 kilometers) in 79 hours, 3 minutes. This was the first ever non-stop flight across the Pacific Ocean.

LZ 127 arrived at Mines Field (now, LAX) at 1:50 a.m., 26 August 1929. There were an estimated 50,000 spectators.

16 August 1927: Not long after Charles A. Lindbergh had flown solo across the Atlantic Ocean, James D. Dole, founder of the Hawaiian Pineapple Company (HAPCO, now the Dole Foods Company, Inc., Westlake Village, California) offered a prize of $25,000 to the first pilots to fly from Oakland Field, Oakland, California, to Wheeler Field, Honolulu, Oahu, Territory of Hawaii, a Great Circle distance of 2,406.05 miles (3,872.16 kilometers). A $10,000 prize was offered for a second-place finisher.

There were 33 entrants and 14 of these were selected for starting positions. After accidents and inspections by the race committee, the final list of starters were down to eight.

Accidents began to claim the lives of entrants before the race even began. A Pacific Aircraft Company J-30 (also known as the Tremaine Hummingbird) flown by Lieutenants George Walter Daniel Covell and Richard Stokely Waggener, U.S. Navy, named The Spirit of John Rodgers, took off from North Island Naval Air Station, San Diego, California, on Wednesday, 10 August, en route to Oakland Field. They had drawn starting position 13. 15 minutes later, in heavy fog, they crashed into the cliffs of Point Loma. Both naval officers were killed.

British aviator Arthur Vickers Rogers was killed in his Bryant Monoplane, Angel of Los Angeles, when it crashed just after takeoff from Montebello, California, 11 August.

One airplane, Miss Doran, made an emergency landing in a farm field, and a fourth, Pride of Los Angeles, flown by movie star Hoot Gibson (Edmund Richard Gibson), crashed into San Francisco Bay while on approach to Oakland. The occupants of those two airplanes were unhurt.

By the morning of 16 August, there were eight entrants remaining. Their starting positions had been selected by a random draw. A little before 11:00 a.m., the first airplane, a Travel Air 5000, registered NX911 and named Oklahoma, took off, but soon aborted the flight because of engine trouble. El Encanto, a Goddard Special, NX5074, crashed on takeoff. A Breese-Wilde Monoplane, PABCO Pacific Flyer, NX646, crashed on takeoff. The crews of these three airplanes were not hurt.

The next airplane to take off was Golden Eagle, the prototype Lockheed Vega. Registered NX913, it was flown by Jack Frost with Gordon Scott as the navigator. It soon disappeared to the west.

The Lockheed was followed by the Buhl CA-5 Air Sedan, NX2915, named Miss Doran. Repairs from its unscheduled landing in the farmer’s field had been accomplished. It was flown by John “Auggy” Pedlar with Lieutenant Vilas Raymond Knope, U.S. Navy, as navigator.

Also aboard was a passenger, Miss Mildred Alice Doran, the airplane’s namesake. She was a 22-year-old fifth-grade school teacher from Flint, Michigan. She knew William Malloska, owner of the Lincoln Petroleum Company (later, CITGO), who had sponsored her education at the University of Michigan. Miss Doran convinced him to enter an airplane in the Dole Air Race and allow her to fly along. Two local air circus pilots reportedly flipped a coin for the chance to fly the airplane in the Dole Air Race. John August (“Auggy”) Pedlar won the toss. Just ten minutes after takeoff from Oakland Field, Miss Doran returned with engine problems.

Next off was Dallas Spirit, a Swallow Special, NX941, with William Portwood Erwin, pilot, and Alvin Hanford Eichwaldt, navigator. It also quickly returned to Oakland.

The last two entrants, a Breese-Wilde 5 Monoplane, NX914, Aloha, with Martin Jensen, pilot, and Captain Paul Henry Schlüter, a master mariner, as navigator; and Woolaroc, a Travel Air 5000, NX869, took off without difficulty.

Miss Doran made a second attempt and took off successfully. PABCO Pacific Flyer also tried again, crashing a second time.

William Virginius Davis, Jr., U.S. Navy, as navigator, flew across the Pacific and arrived at Honolulu after 26 hours, 17 minutes, to win the race. Aloha arrived after 28 hours, 16 minutes of flight. Lieutenant Davis (later, Vice Admiral Davis) was awarded the Distinguished Flying Cross.

29 July 1938: At 12:08 p.m., local time, the Pan American Airways System flying boat Hawaii Clipper lifted off from the waters of Apra Harbor on the west side of Guam, an island in the western Pacific Ocean. The Clipper was on a planned 12½-hour flight to Manila in the Philippine Islands. On board were a crew of nine, with six passengers.

Pan American Airways System brochure, circa 1938. (Smithsonian Institution)

Hawaii Clipper never arrived at its destination. What happened to it and the fifteen persons on board remains one of the enduring mysteries of aviation history.

The flight was designated Trip #229. It had originated at Alameda, on San Francisco Bay, California, and flew to Honolulu in the Hawaiian Islands, then on to Midway Island, Wake Island, and Guam.

The Pan Am crew consisted of Captain Leo Terletzky, First Officer Mark A. Walker, Second Officer George M. Davis, Third Officer Jose M. Sauceda, Fourth Officer John W. Jewett, Engineer Officer Howard l. Cox, Assistant Engineer Officer T.B. Tatum, and Radio Officer William McGarty. The passengers were attended by Flight Steward Ivan Parker.

Captain Terletzky held a Transport Pilot’s License issued by the Aeronautics Branch of the United States Department of Commerce. He had flown more than 9,200 hours, with 1,614 hours in the Martin M-130.

Leo Terletzky (Davis-Monthan Aviation Field Register)

Captain Terletzky (there are alternate spellings, such as Terletsky, and he was also known as Leo Terlitz) was born 18 January 1894 at Odessa, Imperial Russia (now, Ukraine).

Following the Russian Revolution, he left his native country and traveled to Omsk, Siberia, and then to Yokohama, Japan, where he embarked on S.S. Empress of Japan, on 28 March 1919. The passenger liner arrived at Vancouver, British Columbia, Canada, 6 April. He then traveled on to Seattle, Washington, via the Canadian Pacific Railroad, arriving there on 9 April 1919.

Terletzky became a naturalized citizen of the United States of America, 15 December 1924.

On 1 July 1929, he married Miss Helen Sarepta Bowman ¹ at Miami Beach, Florida.

The airliner’s six passengers were: Lieutenant Commander Edward E. Wyman, United States Naval Reserve, of Bronxville, New York. Commander Wyman was a former assistant to Juan Trippe, the founder of Pan American Airways. He was now employed by the Curtiss-Wright Corporation. Pan American’s traffic manager, Kenneth A. Kennedy, was also on board.

Two scientists, Colonel Earl E. McKinley, M.D., United States Army Reserve, Dean of Medicine at George Washington University in Washington, D.C., a bacteriologist, and Fred C. Meier, Ph.D., were collecting airborne bacteriological samples to research transocean bacterial transfer.

Wah Sun Choy

Major Howard C. French, Air Corps, United States Army (Reserve), the commanding officer of the 321st Observer Squadron based at Vancouver, Washington, was also on board.

Finally, there was Wah Sun Choy (also known as “Watson Choy”), of New Jersey. Mr. Choy, an American citizen born in San Francisco, California, in 1901, was the owner of a tea room in Manhattan, New York City, New York, and two restaurants in Jersey City, New Jersey. One of them was named “China Clipper.”

Mr. Sun Choy was believed to be transporting $3,000,000 in U.S. Gold Certificates for the Kuomintang, the Nationalist Party of China, which was headed by Chiang Kai-shek.

Hawaii Clipper was a Martin M-130, NC14714. It was the first of three of the type built for Pan American Airways. With the experimental registration NX14714, it had made its first flight at Middle River, Maryland, 30 December 1934. When Hawaii Clipper departed Alameda, it had flown 4,751:55 hours, TTAF. When it made its last position report, it had flown another 55 hours, 58 minutes.

The Martin M-130 was a large, four-engine flying boat of all-metal construction, designed to carry as many as 36 passengers on transoceanic flights. The M-130 was 90 feet, 10.5 inches (27.699 meters) long with a wingspan of 130 feet, 0 inches (39.624 meters). It was 24 feet, 7 inches (7.493 meters) high. The flying boat had a maximum takeoff weight of 52,252 pounds (23,701 kilograms).

The M-130 was powered by four air-cooled, supercharged Pratt & Whitney Twin Wasp S2A5-G two-row 14-cylinder radial engines with a compression ratio of 6.5:1. The S2A5-G had a Normal Power rating of 830 horsepower at 2,400 r.p.m. to 3,600 feet (1,097 meters), and 950 horsepower at 2,550 r.p.m. for takeoff, using 87-octane gasoline. The engines drove three-bladed Hamilton Standard Hydromatic constant-speed propellers through a 3:2 gear reduction. The S2A5-G was 4 feet, 8.75 inches (1.442 meters) long, 3 feet, 11.88 inches (1.216 meters) in diameter, and weighed 1,235 pounds (560 kilograms).

The airplane had a maximum speed of 180 miles per hour (290 kilometers per hour), and a cruise speed of 130 miles per hour (209 kilometers per hour). The service ceiling was 10,000 feet (3,048 meters). Its range was 3,200 miles (5,150 kilometers).

Hawaii Clipper departed its mooring at Apra Harbor at 11:39 a.m., local time (3:39 a.m., Manila time) and lifted off 29 minutes later. In addition to its six passengers, the airliner was carrying 1,138 pounds (516 kilograms) of cargo. The duration of the flight was estimated as 12 hours, 30 minutes. The M-130 carried sufficient fuel for 17 hours, 30 minutes of flight. Its gross weight was 49,894 pounds (22,632 kilograms) at takeoff, well under its maximum takeoff weight.

At 04:11 Greenwich Civil Time (12:11 p.m., local time), Radio Officer McGarty sent Hawaii Clipper‘s coded 04:00 Ded Reckoning ² position report. The deciphered message read:

Flying in rough air at 9,100 feet. Temperature 13 ˚C., wind 19 knots from 247˚ Position N. 12˚27, E 130˚40, ground speed made good, 112 knots, desired track 282˚. Rain. During past hour conditions varied. 10/10ths sky above covered by strato cumulus clouds, base 9,200 feet. Clouds below 10/10ths sky covered by cumulus clouds whose tops were 9,200 feet. 5/10ths of the hour on instruments. Last DF bearing from Manila 101˚

Great Circle line between Apra Harbor, Guam, and Manila, Luzon, Philippine Islands: 1,592 miles (2,562 kilometers). (Google Maps)

This placed the Clipper approximately 582 nautical miles (670 kilometers) east-southeast of Manila. The transmission was acknowledged. When the land-based radio operator tried to make contact one minute later to provide updated weather information, he received no reply. There were no further radio transmissions from Hawaii Clipper.

When Hawaii Clipper did not arrive at Manila, a large ocean search was begun. On 30 July, the Unites States Army transport ship USAT Meigs discovered an oil slick approximately 28 nautical miles (52 kilometers) south-southeast of the flying boat’s last reported position. The slick was described as being approximately 1,500 feet (457 meters) in circumference.

No physical evidence of the Martin M-130 has ever been found. What happened to cause its disappearance is unknown. While it is assumed that the airplane went down at sea, that might not have been the case. A telephone company employee on Lahuy Island (a small island off the coast of Luzon, east-southeast of Manila) reported having heard a large airplane above the clouds at 3 p.m., Manila Time. In 1938, the number of large airplanes operating in the Philippine Islands must have been fairly limited.

As with the disappearance of Amelia Earhart and Fred Noonan the previous year, there was no shortage of “conspiracy theories.” An example is that agents of the Empire of Japan had stowed away aboard Hawaii Clipper, hijacked the airplane and it was flown to Ulithi, an atoll in the Caroline Islands, and then on to Truk. The story goes on that the passengers and crew were murdered and their bodies buried under the foundation of a hospital then under construction.

Another story is that the Clipper was intercepted by a Japanese flying boat, such as the Kawanishi H6K Type 97 Large Flying Boat, which forced it to fly to an unknown destination, similar to the story above.

Only six months earlier, another Pan American flying boat, Samoan Clipper, a Sikorsky S-42B, NC16734, disappeared about two hours out of Pago Pago in the Samoan Islands. The airliner is believed to have exploded in midair. In that case, an oil slick and wreckage were found.

She was commissioned as a Lieutenant, W-VS, United States Naval Reserve, 4 August 1942. On 1 December 1945, she was promoted to the rank of lieutenant commander, and to commander, 1 January 1950. Mrs. Terletzky had been born at New York City, New York, 28 September 1895. She died at Miami, Florida, 4 August 1970.

² Ded Reckoning (Deductive Reckoning), often erroneously referred to as “dead reckoning,” is a method of navigation which uses a previously known position, time of flight, estimated speed and course of the aircraft based on forecast weather conditions, etc., to estimate the current geographical position. It is the standard method of navigation in the absence of radio aids or satellite position.

Amelia Mary Earhart (24 July 1897– )

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.

Although the exact date of her death is not known, Amelia Mary Earhart (Mrs. George Palmer Putnam) was declared dead in absentia by the Superior Court, County of Los Angeles, 5 January 1939. (Probate file 181709)
