Like Amelia Earhart's disappearance over the Pacific Ocean 70 years ago, the riddle of Steve Fossett's whereabouts is threatening to become one of the world's greatest aviation mysteries.
Nearly two weeks after Fossett's light plane vanished above a vast expanse of rugged Nevada wilderness, an army of rescuers and volunteers are still no closer to locating the millionaire aviator.
And as the frustrating search acres continues to yield no clues, rescue officials say there is a chance that Fossett may never be found.
"That is always a possibility," Lyon County undersheriff Joe Sanford admitted grimly to reporters at Minden Air Base this week.
Fossett has not been heard from since September 3, when he took off on a solo flight from a private airstrip south of Reno, and failed to return as scheduled three hours later.
Since then, a mini air-force of helicopters and planes have taken to the skies in an effort to locate the 63-year-old, a veteran of several world record breaking balloon and plane flights around the globe.
