An America West Airbus jet made an emergency landing at Kansas City International Airport after someone left a note in the plane's bathroom that said: "Taliban is Here."
The plane was flying from Phoenix to Boston Thursday when a passenger saw the note, KCI spokesman Joe McBride said.
The passenger notified the flight crew and the pilot landed the plane at KCI about 1:30 p.m., authorities said.
The FBI, airport police and the Transportation Security Administration responded and police dogs searched the plane. No one was detained or arrested, McBride said.
The passengers were allowed to board the plane again shortly before 4:30 p.m.
