Explorer: Sonar Image Was Rock Formation, Not Amelia Earhart Plane

A sonar image suspected of showing the remains of the plane of Amelia Earhart, the famed American aviatrix who disappeared over the Pacific in 1937, has turned out to be a rock formation.

Deep Sea Vision (DSV), a South Carolina-based firm, released the blurry image in January captured by an unmanned submersible of what it said may be Earhart's plane on the seafloor.

Not so, the company said in an update on Instagram this month, AFP reported.

"After 11 months the waiting has finally ended and unfortunately our target was not Amelia's Electra 10E (just a natural rock formation)," Deep Sea Vision said.

"As we speak DSV continues to search," it said. "The plot thickens with still no evidence of her disappearance ever found."

The image was taken by DSV during an extensive search in an area of the Pacific to the west of Earhart's planned destination, remote Howland Island.

Earhart went missing while on a pioneering round-the-world flight with navigator Fred Noonan.

Her disappearance is one of the most tantalizing mysteries in aviation lore, fascinating historians for decades and spawning books, movies and theories galore.

The prevailing belief is that Earhart, 39, and Noonan, 44, ran out of fuel and ditched their twin-engine Lockheed Electra in the Pacific near Howland Island while on one of the final legs of their epic journey.

Earhart, who won fame in 1932 as the first woman to fly solo across the Atlantic, took off on May 20, 1937 from Oakland, California, hoping to become the first woman to fly around the world.

She and Noonan vanished on July 2, 1937 after taking off from Lae, Papua New Guinea, on a challenging 2,500-mile (4,000-kilometer) flight to refuel on Howland Island, a speck of a US territory between Australia and Hawaii.

They never made it.

Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago.
The footprints were left in the mud by two different species “within a matter of hours, or at most days,” said paleontologist Louise Leakey, co-author of the research published Thursday in the journal Science.
Scientists previously knew from fossil remains that these two extinct branches of the human evolutionary tree – called Homo erectus and Paranthropus boisei – lived about the same time in the Turkana Basin.
But dating fossils is not exact. “It’s plus or minus a few thousand years,” said paleontologist William Harcourt-Smith of Lehman College and the American Museum of Natural History in New York, who was not involved in the study.
Yet with fossil footprints, “there’s an actual moment in time preserved,” he said. “It’s an amazing discovery.”
The tracks of fossil footprints were uncovered in 2021 in what is today Koobi Fora, Kenya, said Leaky, who is based at New York's Stony Brook University.
Whether the two individuals passed by the eastern side of Lake Turkana at the same time – or a day or two apart – they likely knew of each other’s existence, said study co-author Kevin Hatala, a paleoanthropologist at Chatham University in Pittsburgh.
“They probably saw each other, probably knew each other was there and probably influenced each other in some way,” The Associated Press quoted him as saying.
Scientists were able to distinguish between the two species because of the shape of the footprints, which holds clues to the anatomy of the foot and how it’s being used.
H. erectus appeared to be walking similar to how modern humans walk – striking the ground heel first, then rolling weight over the ball of the foot and toes and pushing off again.
The other species, which was also walking upright, was moving “in a different way from anything else we’ve seen before, anywhere else,” said co-author Erin Marie Williams-Hatala, a human evolutionary anatomist at Chatham.
Among other details, the footprints suggest more mobility in their big toe, compared to H. erectus or modern humans, said Hatala.
Our common primate ancestors probably had hands and feet adapted for grasping branches, but over time the feet of human ancestors evolved to enable walking upright, researchers say.
The new study adds to a growing body of research that implies this transformation to bipedalism – walking on two feet — didn’t happen at a single moment, in a single way.
Rather, there may have been a variety of ways that early humans learned to walk, run, stumble and slide on prehistoric muddy slopes.
“It turns out, there are different gait mechanics – different ways of being bipedal,” said Harcourt-Smith.
