A partial outage occurred at an air traffic control facility in Colorado on Monday, according to the Federal Aviation Administration (FAA). The outage lasted approximately 90 seconds and affected some pilots flying over a large portion of the western United States. Controllers were able to re-establish communications using another frequency, ensuring aircraft remained safely separated. This incident follows recent radar outages at an air traffic facility in Philadelphia, which caused significant flight delays at Newark Liberty International Airport. The FAA is currently investigating the cause of the Colorado outage. — new from The New York Times
