Aviation officials say this morning's glitch in a regional radar system caused about 100 departure delays at airports in Southern California and an unknown number of arrival delays.
FAA spokesman Ian Gregor say LAX had 37 departure delays, while Lindbergh Field in San Diego had 29.
He says the FAA grounded every flight in the western United States headed for Southern California for about an hour this morning.
Lindbergh spokeswoman Sharie Shipley says "everything's back up and running but that "it's probably going to take all day to work through the backlog."
The problems started this morning at around 5:30, when the computer mapping system that controllers in San Diego use to guide flights at 21 area airports failed.
Another radar facility in Palmdale handled the incoming flights for the region during the roughly one-hour outage.
