Three flights were canceled Friday morning at Sacramento International Airport due to a fire at an air traffic control center near Chicago.
The early morning fire forced the evacuation of the control center in Aurora, about 40 miles west of downtown Chicago, and halted traffic at the Midwest city’s two airports.
Landing and departure stoppage at two of the nation’s busiest airports sent delays and cancellations rippling through the U.S. air travel network, according to the Associated Press. More than 850 flights were canceled in Chicago alone, and many more cancellations were expected.
A spokeswoman for Sacramento International said that the Sacramento flights canceled included one United departure to Chicago O’Hare Airport, one Southwest departure to Chicago Midway Airport and a Southwest arrival from Chicago Midway Airport.
There were numerous delays listed on the Sacramento International Airport website but it was unclear if they were related to the fire at the air traffic control center.
