CHICAGO (AP) -- Federal officials say new runway equipment has cut the risk of planes colliding at O'Hare International Airport.
The Federal Aviation Administration says a radar-based airfield monitoring system began operating this month. That's almost two years ahead of the FAA's original schedule because of concerns over a series of recent near-collisions.
The new system is designed to give air traffic controllers an earlier warning about potential collisions.
Chicago Department of Aviation spokeswoman Karen Pride says the city's happy the system was installed sooner rather than later.
O'Hare is the eleventh U.S. airport to operate the system. FAA spokeswoman Elizabeth Isham Cory says it's scheduled for Midway Airport in 2008.
