(CNN) – Malaysia Airlines Flight 370 went down in the southern Indian Ocean, Malaysian Prime Minister Najib Razak said Monday, citing a new analysis of satellite data by a British satellite company and accident investigators.
While investigators have yet to find even a piece of the plane, the Prime Minister based his announcement on what he described as unprecedented analysis of satellite data by British satellite provider Inmarsat and the British Air Accidents Investigation Branch.
CEO of the United States Geospatial Intelligence Foundation Keith Masback joins CNN's "The Lead with Jake Tapper" to discuss that data, and how this technology works.
