There is famous scientist from Microsoft, Computer science icon Jim Gray, lost at sea.  I don’t know him, but many do, and look at this effort from Amazon, and others to pull web users everywhere into the search. 

Through a major effort by many people we were able to have the Digital Globe satellite make a run over the area on Thursday morning and have the data made available publicly. We have split these images into smaller tiles that can be easily scanned visually and stored into the Amazon S3 storage service. We then created tasks for reviewing these images and loaded then into the Amazon Mechanical Turk Service.

They arranged a satellite photo update, and have placed that online, using S3 to serve it up.  What an amazing effort, and productive use of web and willing web users to locate Jim.
