What happened to Amelia Earhart?
Earhart vanished over the Pacific in 1937 with navigator Fred Noonan, and the Navy's crash-and-sink theory remains the most accepted explanation.
Covers: The evidence and leading theories about Amelia Earhart's 1937 disappearance over the Pacific, and explains the methods modern expeditions use to locate lost aircraft, including sonar, underwater robotics and archival research. It does not cover unrelated aviation mysteries or Earhart's early life in detail.

The short answer
Evidence-backed AI-prepared starting mapAmelia Earhart disappeared over the Pacific on July 2, 1937, while attempting to become the first female pilot to circumnavigate the world, together with navigator Fred Noonan. After what was then the largest search and rescue attempt in history, the U.S. Navy concluded the pair ditched at sea after running out of fuel — the "crash and sink theory," the most widely accepted explanation. Earhart was declared dead on January 5, 1939. Alternative hypotheses have been considered, and expeditions continue to search suspected crash sites, including a team reported in 2026 heading to a remote island.123

What it means for you
Which fits you?
Pick the situation closest to yours. Each answer says what it rests on.
If you want the short version of what is known
the confirmed facts are the 1937 disappearance with Noonan and the Navy's crash-and-sink conclusion; everything beyond that is hypothesis or ongoing search.12
Evidence-backedIf you are following the 2026 expedition
it was reported as en route to a suspected crash site on a remote island; no result had been reported, so treat any claimed discovery as unconfirmed until a source states it.3
Evidence-backedIf you want to know how sonar, underwater robotics or archival research are used in aircraft searches
this page cannot yet answer that; those methods are in scope but not described by the sources gathered so far.

What happened in 1937
AI summary:Earhart disappeared over the Pacific on July 2, 1937, with navigator Fred Noonan, and was declared dead in 1939.
Evidence-backed: Amelia Mary Earhart (born July 24, 1897) was an American aviator and aviation pioneer. In 1928 she became the first female passenger to cross the Atlantic by airplane, and in 1932 the first woman to make a nonstop solo transatlantic flight, for which she received the Distinguished Flying Cross. She promoted commercial air travel, wrote best-selling books about flying, and helped found the Ninety-Nines, an organization for female pilots. On July 2, 1937, she disappeared over the Pacific while attempting to become the first female pilot to circumnavigate the world. She was declared dead on January 5, 1939.1
Evidence-backed: Earhart was flying with navigator Fred Noonan when the aircraft was lost. The disappearance prompted the largest search and rescue attempt in history up to that time. Afterwards the U.S. Navy concluded that Earhart and Noonan ditched at sea after their plane ran out of fuel — the "crash and sink theory," which remains the most widely accepted explanation. Several alternative hypotheses have also been considered, though the sources here do not set out their details.2
02
How expeditions search for lost aircraft
AI summary:Search efforts continue, with a team reported in 2026 heading to a suspected crash site on a remote island.
Evidence-backed: Search efforts have continued long after the official conclusion. A team reported in October 2026 was en route to a suspected crash site on a remote island, aiming to solve the mystery of the 1937 disappearance. The source does not say what equipment or methods the team planned to use, or what it expected to find.3
Interpretation: The wider question of how modern expeditions locate lost aircraft — through sonar, underwater robotics and archival research — is part of what this page is meant to cover, but the sources available so far do not describe these techniques, what they can detect, or how reliable they are in deep-ocean conditions. Readers should treat any general claims about search technology as not yet supported here.

Earhart disappeared over the Pacific on July , 1937, with navigator Fred Noonan, while attempting the first female circumnavigation of the world; she was declared dead in 1939.
The most widely accepted explanation is the Navy's crash-and-sink theory: the plane ran out of fuel and ditched at sea after the largest search and rescue effort up to that time.
Alternative hypotheses exist, and expeditions are still searching suspected crash sites — a team was reported heading to a remote island in 2026.

“Amelia Mary Earhart ( AIR-hart; born July 24, 1897; disappeared July 2, 1937; declared dead January 5, 1939) was an American aviator and aviation pioneer who became one of the most celebrated figures of early flight. In 1928, she was the first female passenger to cross the Atlantic by airplane. In 1932, she became the first woman to make a nonstop solo transatlantic flight, and was awarded the Distinguished Flying Cross for her achievement. She was one of the first aviators to promote commercial air travel, wrote best-selling books about her flying experiences, and helped found the Ninety-Nines, an organization for female pilots. On July 2, 1937, she disappeared over the Pacific Ocean while attempting to become the first female pilot to circumnavigate the world. Since her disappearance, Earhart has become a global cultural figure and numerous films, documentaries, and books have recounted her life.”

After the largest search and rescue attempt in history up to that time, the U.S. Navy concluded that Earhart and Noonan ditched at sea after their plane ran out of fuel; this "crash and sink theory" is the most widely accepted explanation.
