A fire at an air traffic control facility outside of Chicago, which authorities said was intentionally set by a contract employee of the Federal Aviation Administration, grounded all flights into and out of two Chicago airports on Friday.
The fire forced the evacuation of the air traffic control facility in Aurora, about 40 miles west of Chicago. The man believed to have set the fire was found in the basement of the building with a self-inflicted wound and was taken to the hospital.
The early morning fire was not deemed a terrorist act.
Once the facility was evacuated, management of the region’s airspace was transferred to other facilities, said FAA spokeswoman Elizabeth Cory, reported the Associated Press.
Passengers were waiting in long lines at Chicago O’Hare International Airport to check on their delayed flights.
The Chicago Tribune reported that flights out of the airports started to resume at “a reduced rate” at around 11:45 a.m. EDT.
