O'Hare radars still showing ghost aircraft

May 23, 2000

"Ghosts" continued to haunt O'Hare Airport airspace over the weekend. On Saturday, three separate ghosting incidents--in which nonexistent airplanes mysteriously appeared on radar screens--were reported, air traffic controllers said.

In one instance, a ghost aircraft that was 1.5 miles behind an arriving international flight followed the real 767 when a controller ordered it to turn. A Federal Aviation Administration spokeswoman suggested more ghosts are now being reported because FAA officials encouraged better documenting of the incidents earlier this month. She said safety has not been compromised, and the matter is still being investigated. Over the last few weeks, at least a dozen such images have mysteriously appeared.
