(ABC News) A United Airlines flight was diverted and a family with small children met by the FBI and removed from the plane, all because the parents asked that the movie “Alex Cross” be turned off from the overhead movie screens on their flight.

In a letter to The Atlantic Magazine, the family — who have not been named — said that on United flight 638 from Denver to Baltimore, the PG-13 movie was “Alex Cross,” about a homicide detective that has violent scenes. The parents believed the movie was inappropriate for their 4- and 8-year old boys, but because it was being shown on drop down screens, they couldn’t turn it off themselves.

“Alarmed by the opening scenes, we asked two flight attendants if they could turn off the monitor; both claimed it was not possible,” the letter reads. One of the flight attendants said it was not possible to fold up the screen.
