Many people are scouring up-to-date satellite images of Nevada to try to spot Mr Fossett’s downed plane or wreckage.
The project is being co-ordinated via Amazon’s human-powered problem solving scheme called the Mechanical Turk.
It comes after a frustrating weekend in which searchers failed to turn up any sign of Mr Fossett.
Mr Fossett went missing on 3 September after taking off in his single-engine Citabria aircraft from the Flying M Ranch near Yerington, Nevada. The trip was supposed to last a maximum of three hours.
