CHICAGO — A contract employee who recently was told he was being transferred to Hawaii set a fire at a suburban Chicago air traffic control center where he worked, bringing two of the nation's busiest airports to a halt Friday, according to a criminal complaint filed Friday.
The complaint filed in U.S. District Court in Chicago charges Brian Howard, 36, of Naperville, Illinois, with one count of destruction of aircraft or aircraft facilities, a felony offense.
The FBI said Friday that Howard remains hospitalized due to his injuries and that no court date for him has been scheduled.
A relative who saw a suicidal Facebook note posted on Howard's account early Friday alerted authorities, according to the complaint. Meanwhile, a 911 call from the control center brought a suburban fire department to the scene, where paramedics followed a trail of blood past a gas can, two knives and a lighter, the complaint said.
When they found Howard, he was trying to cut his own throat and told the paramedics to "leave me alone," the complaint said.
Delays and cancellations rippled through the air-travel network from coast to coast after the fire. The ground stoppage at O'Hare and Midway airports immediately raised questions about whether the Federal Aviation Administration has adequate backup plans to keep planes moving when a single facility has to shut down.
By late afternoon, about 1,950 flights in and out of Chicago had been canceled. A few flights resumed around midday, after a nearly five-hour gap. The planes were moving at a much-reduced pace, officials said, and no one could be sure when full service would be restored.
The early morning fire forced the evacuation of the control center in Aurora, about 40 miles west of downtown Chicago. It was the second unexpected shutdown of a Chicago-area air traffic facility since May.
Howard worked for the FAA contractor that supplies and maintains communications systems at air traffic facilities, said Jessica Cigich, a spokeswoman for Professional Aviation Safety Specialists, the union that represents FAA technicians.
"We don't know what his state of mind was at the time," said Thomas Ahern, a spokesman for the Bureau of Alcohol, Tobacco, Firearms and Explosives, which was taking part in the investigation.
The man used gasoline as an accelerant, he said.
When the center was evacuated, management of the region's airspace was transferred to other facilities, FAA spokeswoman Elizabeth Cory said.
But hours after the ordeal began, the region's air traffic was still a mess. The Aurora facility — which had become a crime scene — remained shut down.
The flames badly damaged the center's fiber-optic equipment, leaving controllers unable to talk with pilots, Cigich said.
A control center in Indianapolis called in staff on overtime to patch together inbound and outbound routes for the Chicago area, said Douglas Church, a spokesman for the National Air Traffic Controllers Association labor union. But the process was slow and painstaking because there was no way for other Chicago-area controllers to send flight plans to computers in Indianapolis. That information normally gets routed through the Aurora facility.
"They have had to revert to entering flight-plan information on those aircraft into (their) system by hand," Church wrote in an email.
That led some observers to call for better backup plans.
"This is a nightmare scenario when we thought systems were in place to prevent it," said aviation analyst Joseph Schwieterman of DePaul University in Chicago. "Technology is advancing so fast that ... there's less of a need for air traffic control to be so geographically oriented. I think the FAA's going to find itself under a microscope."
The disruption was also likely to deliver a financial hit to airlines, Schwieterman said.
An FAA spokeswoman in Chicago did not respond to a request for comment about the agency's backup planning.
The shutdown quickly spread travel misery around the country, with airports as close as Milwaukee and as far as Dallas canceling flights. Online radar images showed a gaping hole in the nation's air traffic map over the upper Midwest.
Passengers already in the air headed for Chicago wound up elsewhere. Flight-tracking services showed some Chicago-bound American flights doing loops over Michigan before diverting to Detroit.
Southwest Airlines said it scrapped all of its flights at Midway and Milwaukee for the entire day.
Some passengers simply gave up and returned home.
Brothers Glenn and Gary Campbell, of suburban Chicago, had planned to travel to the Orlando, Florida, area to attend their father's 80th birthday party. Instead, they settled for refunds.
"That it is so easy to disrupt the system is disturbing," said Gary Campbell, a carpenter from Crystal Lake, Illinois. "They need to see how to make sure this kind of thing doesn't happen again."
In May, an electrical problem forced the evacuation of a regional radar facility in suburban Elgin. A bathroom exhaust fan overheated and melted insulation on some wires, sending smoke through the facility's ventilation system and into the control room. That site was evacuated for three hours, and more than 1,100 flights were canceled.
The Aurora facility, known as an enroute center, handles aircraft flying at high altitudes, including those approaching or leaving Chicago airports. Air traffic closer to the airports is handled by a different facility and by the control towers located at the airfields.
