LOS ANGELES: A mission aimed at locating the plane flown by aviation legend Amelia Earhart has ended without finding any evidence of the wreckage, organizers said.

“As is usually the case with field work, we're coming home with more questions than answers,” the Earhart Project said on its website Monday.

“We are, of course, disappointed that we did not make a dramatic and conclusive discovery, but we are undaunted in our commitment to keep searching out and assembling the pieces of the Earhart puzzle.”

The expedition searched the area around Nikumaroro island in Kiribati to test the theory that Earhart survived the apparent crash of her twin-engine Lockheed Electra aircraft.

The searchers, part of the non-profit International Group for Historic Aircraft Recovery, said they would analyze the video taken during the mission launched July 3 for potential evidence.

“We have volumes of sonar data and many hours of high-definition video to review and analyze before we will know whether we found it,” the statement said.

“Due to the limitations of the technology, we were only able to see standard-definition video images during actual search operations. Now that we're examining the recorded high-definition video, we're already seeing objects we want our forensic imaging specialist, Jeff Glickman, to look at.

“We'll also be getting expert second opinions on our best sonar targets.” Earhart was flying with navigator Fred Noonan during the final stage of an ambitious round-the-world flight along the equator when her plane disappeared on July 2, 1937.

The holder of several aeronautical records, including the first woman to cross the Atlantic by air, Earhart had set off from New Guinea to refuel at Howland Island for a final long-distance hop to California.

Several search-and-rescue missions ordered after her disappearance by then-president Franklin Roosevelt turned up no trace of Earhart or Noonan, who were presumed dead at sea.

Google paid tribute Tuesday to Amelia Earhart with the search page “doodle”showing an artist's rendering of the aviation legend, marking the 115th anniversary of her birth.

The doodle is one of many used by the Internet giant to mark occasions or honor individuals.
