Internet users around the globe have joined in the hunt for the missing Malaysia Airlines jetliner as one of the biggest multinational search and rescue campaigns in history came up empty a sixth day.

As of Thursday, more than 100 million map views had been generated on Tomnod.com, a website that provides high-resolution satellite images of the search area for missing flight MH370, said Digital Globe, the parent company of Tomnod.

The site asked visitors to flag clues of the vanished Boeing 777-200ER, such as wreckage, oil slicks or life rafts.
