Friday’s fire, reportedly set by a contact employee at the facility, led to the evacuation of the Chicago Air Route Traffic Control Center in Aurora, Federal Aviation Administration spokeswoman Elizabeth Cory said.

Authorities found a man in the facility’s basement suffering from apparent self-inflicted burn and knife wounds, officials said.

As of 9 a.m. nearly 500 flights to and from O’Hare and Midway airports had been canceled.
