Why Planes Vanish

The disappearance of Flight MH370 stunned the world. In an era of smart-phones and GPS, how could a 270-ton passenger jet vanish into thin air? It was a rude awakening for all of us, showing just how far we are from the world we imagined we lived in—in which every move is monitored all the time. NOVA tells the inside story of the search for Flight MH370 and meets the key players from all corners of the globe who have spent months searching for the lost plane. In the search for answers, we'll reveal how today's planes must fly through vast radar "blind spots," and investigate new technologies that could allow ground stations and satellites to track planes automatically, without pilot intervention, even in remote areas with no radar coverage. What will it take to guarantee that in the future, nothing will ever be 'lost' again?
