Missionary Pilot Bob Norton and five others have been missing for more than three years now.
Their Cessna 182 went down in the Venezuela jungle in February of 2009..but the search for the plane has never ended.
Friends of Bob Norton have staged several aerial and ground searches since then, and turned up nothing.
But a new effort was just completed using new technology to see under the dense canopy of the Amazon jungle.
Volunteers seeking the Alabama medical missionary say they now information from an eyewitness that may change the search area.
BOB EDWARDS, FRIEND AND SEARCH LEADER
"He said it sounded like the plane was not running well and he was fairly low." BUMP "if the plane was as low as he indicated, there is a 50 square mile corridor the crash site should be in."
Edwards says it's all being done on a shoestring budget.
A benefit Concert featuring an Elvis performer and other groups, is set for this Saturday night at the Choo Choo Centennial Theater.
Tickets on sale at Rock Creek.
