The latest in a spate of US air traffic controller suspensions involves an employee at the Cleveland Air Route Traffic Control Centre viewing a movie on a portable DVD player while working a radar position.
"For a little more than three minutes, the controller's microphone was inadvertently activated, transmitting the soundtrack of the movie over the radio frequency of that airspace," says FAA.
The problem was brought air traffic control's attention by the pilot of a military aircraft using an alternate frequency, the agency explains.
Both the controller and the front line supervisor have been suspended from operational duties pending an investigation.
FAA reiterates its policy prohibiting the use of portable DVD players and other devices from being used on the floor of the radar room.
