Dennis McCormack of Rockaway, N.J., checks the departure board Friday only to find out that his flight to Newark, N.J., has been canceled at O’Hare International Airport in Chicago. All flights in and out of Chicago’s two airports were halted Friday after a fire at a suburban air traffic control facility sent delays and cancellations rippling through the U.S. air travel network. Authorities said the blaze was intentionally set by a contract employee of the FAA and had no ties to terrorism.
