One of the reasons Malaysia Airlines flight MH370 hasn't been found is because the plane couldn't be tracked continuously over the ocean. In fact, nearly 3/4 of the globe is untrackable by ground-based radar, the typical way to keep track of aircraft since the 1940s. VOA's Carolyn Presutti explains how one company plans to deploy space-based tracking payloads so that 100% of the earth is trackable and no plane will ever be "lost" again.
