FAA probing O'Hare plane-truck collision

CHICAGO, Oct. 19 (UPI) -- Aviation officials say they're investigating a collision between a taxiing airplane and a maintenance truck at Chicago's O'Hare International Airport.

A United Express jet, operated by SkyWest Airlines, was taxiing on a closed runway at 4:49 a.m. Saturday when it collided with a City of Chicago pickup truck, Federal Aviation Administration spokeswoman Elizabeth Cory told the Chicago Tribune. There were no passengers on the plane, which was being piloted by two maintenance workers, officials said.

"At this point what we have is contact with a city truck," Cory told the newspaper. "An incursion has to be investigated and determined. It's usually a loss of separation … between an aircraft and another aircraft that may be coming to the airport."

The Tribune reported the truck driver was treated at Advocate Lutheran General Hospital in Park Ridge, Ill., and released, while the two mechanics in the plane were treated for minor injuries at Resurrection Medical Center in Chicago.
