The disappearance of Amelia Earhart remains a mystery to this day. One of the most prominent theories surrounding her disappearance is that her plane ran out of fuel. Earhart's last known message was We must be on you, but cannot see you, but gas is running low, indicating that she was aware of the low fuel levels. The plane's estimated fuel capacity was around 1,000 to 1,100 gallons, but the exact amount remaining when she transmitted her final message is uncertain. Some critics argue that the plane did not have enough fuel reserves to reach the Marshall Islands, while others claim that she had up to six hours of fuel remaining. The true amount of fuel Earhart had left when she transmitted her final message remains a subject of debate among experts.

The Electra's fuel capacity
Amelia Earhart was flying a modified Lockheed Model 10 Electra with extra fuel tanks totalling 1,100 gallons. The plane's fuel consumption has been estimated at about 50 gallons per hour, which would give the plane an endurance of 20–21 hours.
Given the distance from Lae to Howland Island, which was 2,560 miles, the anticipated average ground speed was about 140 mph. However, seven hours and twenty minutes into the flight, Earhart reported an average ground speed of only 110 mph, which may have impacted her fuel efficiency.
Thirteen hours into the flight, Earhart could not see Howland Island or get a radio bearing to it, and she soon reached fuel exhaustion. The plane hit the water from an altitude of 1,000 feet and sank before she and her navigator, Fred Noonan, could launch their life raft.
There are several theories about what happened to Earhart and Noonan, including the Marshall Islands landing theory, which suggests that the Electra landed in the Marshall Islands, somewhere north of Howland Island. Another theory suggests that the plane may have gone down on one of the Phoenix Group islands, which lie on the same line-of-position as Howland. Despite searches and ongoing investigations, the mystery of what happened to Amelia Earhart and her navigator remains unsolved.

Earhart's final messages
The mystery of Amelia Earhart's disappearance has captivated people for decades, with many theories and hypotheses being proposed. One of the most well-known theories is that her plane, the Electra, ran out of fuel and crashed into the Pacific Ocean. This theory is supported by Earhart's final messages, which indicated that she was experiencing difficulties and was low on fuel.
At 8:45 a.m., Earhart reported, "We are running north and south." This was the last message heard from the Electra, indicating that Earhart and her navigator, Fred Noonan, were searching for Howland Island by flying along a line of position. By that afternoon, it became evident that the plane had either crashed into the sea or landed elsewhere. Despite a massive search effort by the U.S. Navy, covering 262,281 square miles of the Pacific, neither the Electra nor its crew were ever found.
In addition to these official transmissions, there are accounts of Earhart's final, chilling pleas for help that were heard by people across North America who were listening to their radios. These messages included desperate phrases such as "waters high," "water's knee-deep—let me out," and "help us quick." A housewife in Toronto recalled hearing a similar message, "We have taken in water... we can't hold on much longer," conveying the urgency of the situation.
While the exact amount of fuel Earhart had left is unknown, it is speculated that she did not have enough reserves to reach the Marshall Islands or other potential landing sites. The "Marshall Islands landing theory," proposed by aviator and author Elgen M. Long, suggests that the Electra could not have flown an additional 600 to 800 miles from an area north of Howland Island to reach the southernmost Marshall Islands.

Potential crash sites
Amelia Earhart's disappearance over the central Pacific Ocean remains one of the greatest mysteries in aviation history. Numerous expeditions and searches have been conducted to find her plane, but none have been successful. Here are some of the potential crash sites that have been theorised and explored:
Howland Island:
Howland Island was Earhart's intended stop to refuel before she and her navigator, Fred Noonan, vanished. It is believed that their plane may have crashed into the ocean near Howland Island, and multiple deep-sea searches have been conducted in this area. In 2023, Tony Romeo and his team from Deep Sea Vision captured a sonar image of a plane-shaped object about 16,000 feet below the ocean's surface, roughly 100 miles from Howland Island.
Gardner Island:
Ric Gillespie, who has extensively researched Earhart's flight, proposed that Earhart crash-landed on Gardner Island, about 350 nautical miles from Howland Island. He claims that Earhart transmitted distress calls for nearly a week before her plane was swept out to sea. These calls were reportedly heard not only by the Navy but also by people thousands of miles away in places like Florida, Iowa, and Texas. Gillespie's organisation, the International Group for Historic Aircraft Recovery (TIGHAR), has also found forensic evidence, including bones, that may belong to Earhart.
Mili Atoll, Marshall Islands:
The Marshall Islands landing theory suggests that Earhart's plane may have reached the Marshall Islands, specifically Mili Atoll. This theory has been supported by renowned aviator and author Elgen M. Long, who argues that the Electra ran out of fuel shortly after Earhart's last message. However, critics argue that the plane did not have sufficient fuel reserves to reach the southernmost Marshall Islands from an area north of Howland Island.
Phoenix Group Islands:
TIGHAR is also investigating the possibility that the Electra missed Howland Island and turned south, reaching one of the small Phoenix Group Islands, such as Baker, McKean, or Gardner (now Nikumaroro). A search of Nikumaroro revealed aircraft parts similar to those on Earhart's Electra and a 1930s woman's shoe heel.
Siapan:
There have been reports of Earhart's plane going down near Siapan, an island closer to Howland than the Marshall Islands. Some U.S. Naval personnel shared stories of two flyers, a man and a woman, who crashed and were taken captive by the Japanese. However, remains found on Siapan were later determined not to belong to Earhart or Noonan.

The Marshall Islands theory
The disappearance of Amelia Earhart and Fred Noonan in 1937 has sparked several theories about their whereabouts and fate. One of the most well-known theories is the Marshall Islands theory, which suggests that Earhart and Noonan crashed in the Marshall Islands, which were under Japanese rule at the time.
However, critics of the Marshall Islands theory, also known as "Amelia Earhart's Mili Atoll landfall," argue that the Electra aircraft likely did not have sufficient fuel reserves to reach the southernmost Marshall Islands. It is estimated that the plane would have needed to fly an additional 600 to 800 miles, which critics consider unlikely given the fuel constraints.

The Nikumaroro hypothesis
The hypothesis was developed by The International Group for Historic Aircraft Recovery (TIGHAR) through documentary records, photos, satellite images, physical evidence, and personal testimony. Some of the evidence found on the island includes aircraft parts similar to those on Earhart's Electra, a heel from a woman's shoe from the 1930s, a compact case, a medicine vial, and a bottle of freckle concealer.
Critics of the hypothesis argue that TIGHAR's founder and executive director, Richard Gillespie, lacks credible results from his expeditions. A 2019 expedition led by ocean explorer Robert Ballard to locate Earhart's plane or evidence of it landing on Nikumaroro turned up no evidence.
However, proponents of the hypothesis point to additional evidence such as three recorded radio transmissions converging near the island and the Taraia Object, a visual anomaly believed to be the remains of Earhart's plane. The Taraia Object was first identified in satellite images from 2015 and 2016 and was also spotted in drone footage from 2017 and aerial photographs from 1938.
Research trips to Nikumaroro continue, with the hope of finding more evidence to support the hypothesis and solve the mystery of what happened to Amelia Earhart.
