When a 777 lands in water its emergency locator transmitter is supposed to automatically broadcast a distress signal to satellites. That never happened with Flight 370. Anderson takes a closer look at an ELT with David Gallo,who co-led the search for Air France Flight 447, aviation analyst Les Abend, former U.S. Department of Transportation Inspector General Mary Schiavo and safety analyst David Soucie.
Anderson Cooper goes beyond the headlines to tell stories from many points of view, so you can make up your own mind about the news. Tune in weeknights at 8 and 10 ET on CNN.
