There is still no sign of Flight 370. There is no way to know which direction the plane was flying after its transponder stopped broadcasting. No one has spotted a single piece of debris from the Boeing 777. But there are plenty of theories about what may have happened. As we learn more about the signals the plane may have been broadcasting, Anderson discussed the possible scenarios with airline pilot Ron Brown, National Security Analyst and former White House Homeland Security Adviser Fran Townsend and former NTSB member John Goglia.
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.
