Staff at satellite communications company Inmarsat work in front of a screen showing subscribers using their service throughout the world, at their headquarters in London March 25, 2014. Britain's Inmarsat used a wave phenomenon discovered in the nineteenth century to analyse the seven pings its satellite picked up from Malaysia Airlines Flight MH370 to determine its final destination.The new findings led Malaysian Prime Minister Najib Razak to conclude that the Boeing 777, which disappeared more than two weeks ago, crashed thousands of miles away in the southern Indian Ocean, killing all 239 people on board.
