Chicago:
Chicago Aviation Department officials said on Thursday that a passenger plane slid off the runway at O'Hare International Airport after it returned there because of mechanical problems.
Spokesman Gregg Cunningham said that nobody was injured aboard the American Eagle plane that left the runway shortly before 9 am on Thursday.
Mr Cunningham said the plane had taken off from O'Hare headed for Tulsa, Oklahoma, when the pilot reported mechanical problems and turned around to return to O'Hare.
He said that after the plane landed, it came to a stop on a paved area and the passengers were taken by buses to another gate.
