Noonan and Earhart expected to do voice communications on 3105kHz during the night and 6210kHz during the day.

Proposals have included the uninhabited Gardner Island, 400mi (640km) from the vicinity of Howland, the Japanese-controlled Marshall Islands, 870mi (1,400km) at the closest point of Mili Atoll, and the Japanese-controlled Northern Mariana Islands, 2,700mi (4,300km) from Howland. Crystal control means that the transmitter cannot be tuned to other frequencies; the plane could transmit only on those three frequencies.

Polhemous, the navigator on Ann Pellegreno's 1967 flight that followed Earhart and Noonan's original flight path, studied navigational tables for July 2, 1937, and thought Noonan may have miscalculated the "single line approach" intended to "hit" Howland. Note 38] [194] [Note 39] Sporadic signals were reported for four or five days after the disappearance but none yielded any understandable information. Between Earhart's low-on-fuel message at 7:42am and her last confirmed message at 8:43, her signal strength remained consistent, indicating that she never left the immediate Howland area as she ran out of fuel. However, a few moments later she was back on the same frequency (3105kHz) with a transmission that was logged as "questionable": "We are running on line north and south.

The Electra failed to establish two-way radio communications with USCGC Itasca (1929) and failed to radiolocate Itasca. Earhart's 7:58am transmission said she could not hear the Itasca and asked them to send voice signals so she could try to take a radio bearing. The 157/337 radio transmission suggests they flew a course of 157° that would take them past Baker Island; if they missed this, then sometime later they would fly over the Phoenix Islands, now part of the Republic of Kiribati, about 350 nautical miles (650km) south-southeast of Howland Island. Earhart subsequently made her first attempt at competitive air racing in 1929 during the first Santa Monica-to-Cleveland Women's Air Derby (nicknamed the "Powder Puff Derby" by Will Rogers), which left Santa Monica, California, on August 18 and arrived at Cleveland, Ohio on August 26.Ric Gillespie of TIGHAR believes that based on Earhart's last estimated position, somewhat close to Howland Island, it was impossible for the aircraft to end up at New Britain, 2,000 miles (3,200km) and over 13 hours' flight time away. A slightly different version of the Japanese capture hypothesis is not that the Japanese captured Earhart, but rather that they shot down her plane. A Brandis and Sons sextant with serial number 3500 would have been made around the time of World WarI. Rather than simply endorsing the products, Earhart actively became involved in the promotions, especially in women's fashions. Amelia Earhart: The first female pilot to fly solo across the Atlantic, Amelia Earhart’s life is full of inspiration for your little adventurer.

By the time I had got two or three hundred feet [60–90m] off the ground," she said, "I knew I had to fly. Five years later in 1914, he was forced to retire and although he attempted to rehabilitate himself through treatment, he was never reinstated at the Rock Island Railroad. It is not certain, but it is likely that the dorsal antenna was only connected to the transmitter (i. These would be consistent with a Lockheed Electra 10E, such as that flown by Earhart, although they do not contain enough information to identify the wreck in question as NR16020. Around 3pm Lae time, Earhart reported her altitude as 10,000ft but that they would reduce altitude due to thick clouds.

She was booked for a passenger flight the following day at Emory Roger's Field, at the corner [50] of Wilshire Boulevard and Fairfax Avenue.
