A college student's science project prompted a panic at Dallas Love Field airport yesterday, with authorities evacuating hundreds of people and detaining 11 passengers. As college students and their professor exited a Southwest Airlines plane that had flown in from Kansas City, one left a "robotic device" on board; a passenger said it looked like a remote-control car linked to a phone. Security personnel shouted orders to evacuate the terminal, and a number of handcuffed students were escorted from the gate. A bomb squad found the gadget to be safe within an hour, the Dallas Morning News reports. (More college student stories.)
