An American Airlines flight made an emergency landing in Dulles after the plane's first officer became ill during the flight.

American Airlines spokesman Kent Powell said the first officer complained of feeling ill, and decided to land the plane at about 11:15 a.m. on Saturday. There were 141 passengers on board the Dallas-bound plane out of Newark. Passengers boarded another aircraft at about 2 p.m.

Powell said the officer has been released from the hospital, but did not say what his ailment was.
