Aviation security under the microscope
Federal officials are trying to figure out how a man was able to bring explosive material and ignite it on board a Northwest Airlines flight on Saturday. That the incident didn't turn tragic was due in part to the actions of the passengers on the plane. In the meantime, flyers will experience new travel security restrictions that vary depending on where you're flying.
