An anonymous reader invites us to join in the hunt for the missing Steve Fossett using Amazon's Mechanical Turk. DigitalGlobe, one of Google's imaging partners, has acquired new high-resolution satellite imagery of the area where Fossett disappeared on Monday. The public can now go through this imagery and quickly flag any images that might contain Fossett's plane. Flagged images will receive further review by search and rescue experts.
