Update: 18:00 GMT Thanks to SpOOky for the following extra info/specualtion.
During Earhart and Noonan's approach to Howland Island the Itasca received strong and clear voice transmissions from Earhart identifying as KHAQQ but she apparently was unable to hear voice transmissions from the ship.
Her 7:58 a.m. transmission said she couldn't hear the Itasca and asked them to send voice signals so she could try to take a radio bearing They couldn't send voice at the frequency she asked for, so Morse code signals were sent instead. Earhart acknowledged receiving these but said she was unable to determine their direction
Also Losts Amelia Looks quite like Amelia Earheart (Atleast to me )
In the episode Not in Portland there is a Anagram with her´s last name ( Herarat Aviation )
Some bio about her
" In 1937, as Earhart neared her 40th birthday, she was ready for a monumental, and final, challenge. She wanted to be the first woman to fly around the world. Despite a botched attempt in March that severely damaged her plane, a determined Earhart had the twin engine Lockheed Electra rebuilt. "I have a feeling that there is just about one more good flight left in my system, and I hope this trip is it," she said. On June 1st, Earhart and her navigator Fred Noonan departed from Miami and began the 29,000-mile journey. By June 29, when they landed in Lae, New Guinea, all but 7,000 miles had been completed. Frequently inaccurate maps had made navigation difficult for Noonan, and their next hop--to Howland Island--was by far the most challenging. Located 2,556 miles from Lae in the mid-Pacific, Howland Island is a mile and a half long and a half mile wide. Every unessential item was removed from the plane to make room for additional fuel, which gave Earhart approximately 274 extra miles. The U.S. Coast Guard cutter Itasca, their radio contact, was stationed just offshore. Three other U.S. ships, ordered to burn every light on board, were positioned along the flight route as markers. "Howland is such a small spot in the Pacific that every aid to locating it must be available," Earhart said.
At 12:30 p.m. on July 2, the pair took off. Despite favorable weather reports, they flew into overcast skies and intermittent rain showers. This made Noonan's premier method of tracking, celestial navigation, impossible. As dawn neared, Earhart called chief radioman Leo G. Bellarts and asked for Itasca's location. She failed to report at the next scheduled time, and afterward her radio transmissions, irregular through most of the flight, were faint or interrupted with static. At 7:42 A.M. the Itasca picked up the message, "We must be on you, but we cannot see you. Fuel is running low. Been unable to reach you by radio. We are flying at 1,000 feet." The ship tried to reply, but the plane seemed not to hear. At 8:45 Earhart reported, "We are running north and south." Nothing further was heard from Earhart.
A rescue attempt commenced immediately and became the most extensive air and sea search in naval history thus far. On July 19, after spending $4 million and scouring 250,000 square miles of ocean, the United States government reluctantly called off the operation. In 1938, a lighthouse was constructed on Howland Island in her memory. Today, though many theories exist, there is no proof of her fate. There is no doubt, however, that the world will always remember Amelia Earhart for her courage, vision, and groundbreaking achievements, both in aviation and for women. In a letter to her husband, written in case a dangerous flight proved to be her last, this brave spirit was evident. "Please know I am quite aware of the hazards," she said. "I want to do it because I want to do it. Women must try to do things as men have tried. When they fail, their failure must be but a challenge to others.""
