A passenger on a JetBlue flight opened an emergency exit door and deployed the slide while the plane was taxiing at Logan Airport Tuesday night, the FAA said.

A man will face charges after officials say he opened the door of a plane departing Boston’s Logan Airport on Tuesday night, startling fellow passengers and triggering a large police response.

The passenger on the JetBlue flight opened an exit “for unknown reasons” while the airplane was taxiing, or moving on the runway.
