Denver International Airport spokesman Chuck Cannon says a radar problem that grounded outbound flights at Denver International Airport for about an hour this evening has been fixed.
Cannon says the problem was reported about 6 p.m. and the radar was back on shortly after 7 p.m.
Cannon says operations were back to normal by 8:30 p.m.
Some flights landed during that time with the help of another FAA traffic control center, says Mike O'Connor, an FAA regionalduty officer, in Renton, Washington.
23 flights were stopped on the runways. Pilots were shutting down the planes to conserve on fuel.
