A robotic device accidentally left aboard a Southwest Airlines jet shutdown Dallas' Love Field and resulted in law officers detaining 11 passengers.
According to Southwest Airlines spokesman Paul Flanagan, crews prepping a jet after a flight from Amarillo found the device on a plane behind the cockpit around 4 p.m.
In a statement, the City of Dallas said Air Marshals detained 11 passengers related to the robot.
"It was determined that the device was not dangerous and was a student's science project," the statement said. "The student was traveling with fellow students and a professor. That student told authorities the robot was accidentally left on the plane."
Dallas' Love Field was shut down until the all clear was given.
Southwest Airlines said several flights were delayed from departing or arriving at Love Field while the incident was investigated. But flights resumed normal schedule by 5 p.m.
