Earhart saw her first aircraft at the Iowa State Fair in Des Moines, and her father attempted to interest her to take a flight. But it wasn’t until 1920, when Earhart was 23, that she started taking flying lessons.

▲Born in Atchison, Kansas, Earhart and her little sister Grace, whom she called Pidge, were not raised to be "nice little girls," according to the Amelia Earhart Project’s website.

▲In 1932, Earhart became the first woman to fly across the Atlantic solo.

▲Earhart, however, lost control of her Lockheed Electra 10E on takeoff and had to send her plane to the factory for repairs.

▲In June 1937, she went to Miami to resume her attempt to fly around the world, this time with Fred Noonan as her navigator.

▲The pair chose to leave important communication and navigation instruments behind for unknown reasons. One theory is that they wanted to make room for additional fuel for the long flight.

▲The pair arrived in New Guinea 21 days later. The next leg was to fly from New Guinea to Howland Island, a tiny island in the middle of the Pacific Ocean.

▲In March 1937, Earhart flew to Hawaii with fellow pilot Paul Mantz to begin the flight that would have made her the first person of any gender to circumnavigate the globe at the Equator, the earth’s widest point.

▲Earhart was last heard from on July 2, 1937, when she last communicated with a nearby Coast Guard ship. She, Noonan, and her famed plane were never seen again.

▲The U.S. Navy conducted a massive search for more than two weeks. Unable to accept that Earhart had just disappeared and died, many of her admirers began to formulate the theory that she was a either a spy or was captured by enemies of the United States.

▲Two years later in 1939, the US government legally declared both Earhart and Noonan dead, though their remains were never found.

▲In the summer of 2017, a documentary team with the History Channel unearthed a photo that reportedly showed her in the Marshall Islands. The running hypothesis was that she had survived the crash and stayed in the Pacific.

▲After the photo surfaced, however, two bloggers found the original photo in a Japanese photo book displaying a date: 1935, when Earhart was around and well. The mystery continued.

▲In 1940, British officials discovered 13 human bones on Nikumaroro, an uninhabited island in the South Pacific.

▲That same year, physician D.W. Hoodless analyzed the bones and determined that they belonged to a short, European man.

▲In 1998, a group of researchers from the International Group for Historic Aircraft Recovery reexamined Dr. Hoodless’s measurements and concluded they could have belonged to a tall woman.

▲In 2001, a previous search crew found possible signs of a castaway, including the remains of various campfires, and US-made items such as a jackknife, a woman’s compact, a zipper pull, and glass jars on the island.

▲Earhart was about 5 ft 7 in or 5 ft 8 in, so hope and interest were reintroduced.

▲In June 2017, the same international group sent an expedition of archaeologists with forensic dogs to Nikumaroro in search of other bones, but it was unsuccessful.

▲It had been three years since Earhart had gone missing. The search party also found part of a shoe, apparently a woman’s, an old-fashioned sextant box similar to the kind she used, and a Benedictine bottle, something Earhart was known to carry.

▲The group suggested that Earhart and Noonan may have landed on Nikumaroro and survived for at least several days, sending distress signals.

▲Adding to the mystery surrounding Earhart’s story, the bones disappeared after being examined in the late 1990s. All that remains are measurements of the skull, tibia, humerus, and radius.

▲Richard Jantz, emeritus professor and director of the University of Tennessee’s Forensic Anthropology Center, set out to conduct a more in-depth analysis.

▲In his published findings, Jantz concluded that the remains have a high statistical probability of belonging to Earhart.

▲Using different investigative techniques, including a computer program that estimates sex, ancestry, and stature from skeletal measurements, Jantz concluded that Hoodless was incorrect in his gender assessment back in 1940.

▲

Jantz determined that “until definitive evidence is presented that the remains are not those of Amelia Earhart, the most convincing argument is that they are hers.”

▲In his paper, Jantz wrote that “Earhart is more similar to the Nikumaroro bones than 99% of individuals in a large reference sample.”

▲Jantz compared the bones' measurements to Earhart’s measurements taken by a seamstress. The document was kept in the George Palmer Putnam Collection of Amelia Earhart Papers at Purdue University.

▲Jantz also considered the possibility that the bones belonged to one of the 11 British men who died near the island in a 1929 shipwreck. However, no documentation supports this hypothesis. Besides, the 2001 search party found a shoe and other objects commonly associated with women at the site.

Sonar images captured in January revealed an object resembling an airplane on the ocean floor, about 100 miles (161 kilometers) from Howland Island in the Pacific. This island was Amelia Earhart’s intended destination before her disappearance. The finding reignited global interest in the enduring mystery, with many believing it could be the wreckage of her missing Lockheed 10-E Electra.

However, on November 1, Deep Sea Vision, a Charleston-based ocean exploration company responsible for the discovery, revisited the site and determined that the anomaly was, in fact, a natural rock formation. This revelation has prolonged the quest to uncover the fate of the pioneering aviator.
