TAMPA (WFLA) — An explorer and his team believe they have found the answer to one of the greatest mysteries in U.S. history.

Deep Sea Vision, a Charleston, South Carolina-based team that provides survey equipment for deep sea exploration, said it has uncovered a sonar image in the Pacific Ocean that appears to be the Lockheed 10-E Electra aircraft that belonged to Amelia Earhart and navigator Fred Noonan, who were last seen then they took off from Papua New Guinea on July 2, 1937, near the end of their journey across the world.

The company said it scanned more than 5,200 square miles of ocean floor with a 16-person crew before finding what could be Earhart’s missing plane.

“There’s no other known crashes in the area, and certainly not of that era in that kind of design with the tail that you see clearly in the image,” Tony Romeo, CEO of Deep Sea Vision, said during an interview with NBC’s “TODAY” show.

NBC reports Romeo and his team plan to return to the site later this year or early next year to grab a better image of the possible wreckage.

“The next step is confirmation and there’s a lot we need to know about it. And it looks like there’s some damage. I mean it’s been sitting there for 87 years at this point,” Romeo said.
