Daily Herald (Arlington Heights, Ill., April 11) – Chicago police reported that David Dao, a passenger who was dragged off a United Airlines flight Sunday, became irate and started yelling after being asked to leave the plane, at which point Chicago Department of Aviation security officers were called. “Airlines can remove a passenger if they believe the passenger poses a threat to the flight,” says aviation security expert Sheldon H. Jacobson, a professor at Illinois.
