Richard Branson: Soon we'll fly anywhere in the world in 30 minutes

More than 1,800 flights were canceled Friday after a contractor started a fire and attempted to commit suicide at an air traffic control center in Illinois. All it took was one man's actions to completely snarl air traffic across the United States. But Virgin Group founder Richard Branson says that could soon become a thing of the past. He has a new book "The Virgin Way." In interview with CNN's Erin Burnett, Branson explains why he believes supersonic travel is coming soon.
