What happened
AI-written · may contain mistakes. Written from the advisory text and weather only.
Cause: The airport had more flights than it could handle at once, so departures headed there were held back. Weather was not the problem; visibility was 10 miles.
The ground stop began at 00:37 UTC on October 23 and was scheduled to run until 6:45 pm Pacific time. It ended at 01:31 UTC, after 54 minutes. Departures were held from several air traffic control centers, and an advisory had warned the stop might be extended.
