There is little evidence that Malaysian Airlines Flight 370 was brought down by an act of terrorism, NBC News Reported. No electronic "chatter" from known terror groups has been detected three days after the last contact with the missing China-bound flight. U.S. federal investigators are looking over surveillance video from the flight's point of origin and travel patterns corresponding with two stolen passports that were used to board the aircraft. Al-Qaeda and other fundamentalist groups normally seek credit for attacks that they've organized.
