The Salt Lake City International Airport's radar system crashed on Friday, but no planes did during the six-hour outage.

Airport officials said the radar outage between 8:30 a.m. and 2:30 p.m. did not put the public in danger, and no flights were canceled, but air traffic in and out of the airport was slowed."(The radar units) were scheduled for shutdown later that night for repairs . . . but it didn't wait for them," said airfield operations manager Frank Ratliff. "There was no jeopardy (to passengers) involved."

Ratliff said such unexpected shutdowns are rare, but the airport can continue to operate safely for short periods without its radar.
