Thirteen countries, 57 ships and 48 aircraft are currently looking for Malaysian Airlines flight MH370, which has been missing since last Friday.
But since a few hours after the plane and its 239 passengers disappeared, the search has been joined by some 2.3 million ordinary internet users, who are using the Tomnod website to scan more than 24,000 sq km of satellite imagery to help locate the missing aircraft.
Tomnod is run by commercial satellite company DigitalGlobe, which soon after the plane’s disappearance repositioned two of its five satellites over its last known location in the Gulf of Thailand, and have since moved them as the search headed west.
