An expedition to find the remains of aviator Amelia Earhart's lost aircraft has turned up little so far, according to an NPR report.

Earhart, most known as the first woman to fly solo across the Atlantic Ocean, disappeared somewhere in the Pacific Ocean during an attempt to fly around the world.

The Niku VII expidition kicked off last July, sending Hawaiian Research Vessel Ka'imiakai-o-Kanaloa ("Heavenly Searcher of the Sea") to comb an island reef in the mid-Pacific for wreckage. The site of the search was chosen because of a photo taken off the island's coast just three months after Earhart disappeared in October 1937.

According to the most recent press release from the International Group for Historic Aircraft Recovery (TIGHAR), large pieces of wreckege were not immediately visible, but this is hardly surprising after 75 years in the island's "severe and unstable underwater environment" However, they have not yet finished going through the hours of high-definition video recordings.

The release notes that they have already begun to see possible clues in the video that they plan send to their forensic imaging specialist, and that they should have some results by the time their Discovery Channel special airs on August 19th.
