COLUMBIA, S.C. (AP) 鈥 A grainy sonar image recorded by a private pilot has reinvigorated interest in one of the past century鈥檚 most alluring mysteries: What happened to Amelia Earhart when her plane vanished during her flight around the world in 1937?
have turned up nothing, only confirming that swaths of ocean floor held no trace of her twin-tailed monoplane. Tony Romeo now believes his new South Carolina-based sea exploration company captured an outline of the iconic American鈥檚 Lockheed 10-E Electra.
Archaeologists and explorers are hopeful. But whether the tousled-haired pilot's plane lies at the roughly 16,000-foot (4,800-meter) depth remains to be seen. And debates abound about the proper handling of whatever object is discovered.
Archivists are hopeful that Romeo鈥檚 Deep Sea Vision is close to solving the puzzle 鈥 if for no other reason than to return attention to Earhart鈥檚 accomplishments.
Regardless, the search is on for the .
HOW DID DEEP SEA VISION DETECT THE OBJECT THAT COULD BE EARHART'S PLANE?
Romeo wanted more of an adventure than his commercial real estate career. His father flew for Pan American Airlines, his brother is an Air Force pilot and he has a private pilot's license himself. Hailing from an 鈥渁viation family,鈥 he'd long held interest in the Earhart mystery.
Romeo said he sold his real estate interests to fund last year's search and buy a $9 million underwater drone from a Norwegian company. The state-of-the-art technology is called the Hugin 6000 鈥 a reference to its ability to break into the deepest layer of the ocean at 6,000 meters (19,700 feet).
A 16-person crew began a roughly 100-day search in September 2023, scanning over 5,200 square miles (13,468 square kilometers) of seafloor. They narrowed their probe to the area around Howland Island, a mid-Pacific atoll between Papua New Guinea and Hawaii.
But it wasn't until the team reviewed sonar data in December that they saw the fuzzy yellow outline of what resembles a plane.
鈥淚n the end, we came out with an image of a target that we believe very strongly is Amelia鈥檚 aircraft," Romeo told The Associated Press.
The next step is taking a camera underwater to better examine the unidentified object. If the visuals confirm the explorers' greatest hopes, Romeo said the goal would be to raise the long-lost Electra.
Ultimately, Romeo said his team undertook the costly adventure to 鈥渟olve aviation's greatest unsolved mystery.鈥 An open hatch could indicate that Earhart and her flight companion escaped after the initial impact, Romeo said, and a cockpit dial could lend insight into what, exactly, went wrong.
FROM ALIEN ABDUCTION TO JAPANESE EXECUTION, THEORIES ABOUND
Earhart and her navigator, Fred Noonan, disappeared while flying from New Guinea to Howland Island as part of her attempt to become the first female pilot to circumnavigate the globe. She had radioed that she was running low on fuel.
The Navy searched but found no trace. The U.S. government's official position has been that Earhart and Noonan went down with their plane.
Since then, theories have veered into the absurd, including abduction by aliens, or Earhart living in New Jersey under an alias. Others speculate she and Noonan were executed by the Japanese or died as castaways on an island.
鈥淎melia is America鈥檚 favorite missing person," Romeo said.
Deep Sea Vision鈥檚 is hardly the first foray. David Jourdan said his exploration company Nauticos searched in vain on three separate expeditions between 2002 and 2017, surveying an area of seafloor about the size of Connecticut. Those efforts were preceded by a $1 million hunt in 1999 from Nevada-based Dana Timmer. As recently as 2014, Timmer had not given up and sought to raise nearly $2 million for another go.
Between 1988 and 2002, the International Group for Historic Aircraft Recovery made six trips to a different island in the western Pacific Ocean under the impression that Earhart crash-landed on a flat reef 1,800 miles (2,900 kilometers) south of Hawaii.
Hillary Clinton, then the U.S. Secretary of State, encouraged the group in 2012 when it launched a new search for the wreckage fueled by analysis of a 1937 photo believed to show the Lockheed Electra鈥檚 landing gear jutting out of the island鈥檚 shoreline.
鈥榃E NEED TO SEE MORE鈥
Maritime archaeologist James Delgado said Romeo鈥檚 potential find would change the narrative, but 鈥渨e need to see more.鈥
鈥淟et鈥檚 drop some cameras down there and take a look,鈥 said Delgado, senior vice president of the archaeological firm SEARCH Inc.
Delgado said Romeo's expedition employed world-class, cutting-edge technology that was once classified and is 鈥渞evolutionizing our understanding of the deep ocean."
But he said Romeo鈥檚 team must provide 鈥渁 forensic level of documentation鈥 to prove it鈥檚 Earhart鈥檚 Lockheed. That could mean the patterns in the fuselage鈥檚 aluminum, the configuration of its tail and details from the cockpit.
Jourdan, of Nauticos, would have expected to see straight wings and not swept wings, like the new sonar suggests, as well as engines. But that could be explained by damage to the aircraft or reflections distorting the image, he acknowledged.
鈥淚t could be a plane. It certainly looks like a plane. It could be a geological feature that looks like a plane,鈥 he said.
Dorothy Cochrane, an aeronautics curator at the National Air and Space Museum, said Romeo's crew searched in the right place near Howland Island. That's where Earhart desperately sought a runway when she disappeared on the last leg of her flight.
If the object really is the historic aircraft, the question for Cochrane will be whether it is safe to raise. How much of the machinery is still intact would be determined in part by how smoothly Earhart landed, she added.
鈥淭hat's where you have to really look at this image and say, 鈥榃hat have we got here?鈥欌 said Cochrane.
WHAT IF EARHART'S LOCKHEED ELECTRA HAS BEEN FOUND?
If the fuzzy sonar images turn out to be the plane, international standards for underwater archaeology would strongly suggest the aircraft remain where it is, said Ole Varmer, a retired attorney with the National Oceanic and Atmospheric Administration and a senior fellow at The Ocean Foundation.
Nonintrusive research can still be conducted to reveal why the plane possibly crashed, Varmer said.
鈥淵ou preserve as much of the story as you can,鈥 Varmer said. 鈥淚t鈥檚 not just the wreck. It鈥檚 where it is and its context on the seabed. That is part of the story as to how and why it got there. When you salvage it, you鈥檙e destroying part of the site, which can provide information.鈥
Raising the plane and placing it in a museum would likely cost hundreds of millions of dollars, Varmer said. And while Romeo could conceivably make a salvage claim in the courts, the plane鈥檚 owner has the right to deny it.
Earhart bought the Lockheed with money raised, at least in part, by the Purdue Research Foundation, according to a blog post by Purdue University in Indiana. And she planned to return the aircraft to the school.
Romeo said the team believes the plane belongs in the Smithsonian. Acknowledging the 鈥渦ncharted territory鈥 of potential legal issues, he said his exploration company will "deal with those as they come up."
