It’s been five days since adventurer Steve Fossett disappeared in the Nevada desert. So far, searchers have found half a dozen previously unknown crash sites, but no sign of Fossett’s plane.

Amazon is now involved and has set up a Mechanical Turk project where volunteers can view recent satellite photos and search for the plane. The project is located here. Amazon also gives instructions on that page to view the images in Google Earth.

A similar project was created to search for computer scientist Jim Gray when he was lost at sea earlier this year, but Gray was never found.
