Amelia Earhart, whose 115th birthday is celebrated on Google's home page Tuesday, disappeared with her navigator over the Pacific Ocean in 1937. A new search for her remains has returned nothing definitive.
Even though a monthlong voyage for Amelia Earhart's plane wreckage turned up nothing definitive, the searchers devoted to the hunt say they have a trove of evidence to examine that will help shed light on what happened to the famed aviator 75 years ago.
The expedition to a remote atoll roughly 2,000 miles (3,200 kilometers) southwest of Hawaii was well on its way back to Honolulu on Tuesday as Earhart's family and others marked what would have been the American icon's 115th birthday.
Google honored Earhart by changing the logo on its homepage, while her family said on their website that Earhart's legacy remains relevant.
"The aviation pioneer, who was the first female pilot to cross the Atlantic Ocean, continues to make lasting impressions on people all over the world," the statement posted Tuesday said.
Pat Thrasher, president of The International Group for Historic Aircraft Recovery, said plans are already in the works for a land-based expedition to the Kiribati atoll of Nikumaroro next year.
The voyagers looked at footage as it initially came in from a tethered underwater vehicle rigged with cameras and lights. But the group expects to learn more through repeat viewings, picking up new insights on the underwater landscape where they believe the plane went down. The group has countless hours of high-definition video and sonar data.
