Multiple Commercial Flights Report Severe GPS Disruptions
Multiple commercial flights, including United Airlines and Alaska Airlines, reported severe GPS jamming while operating in the airspace near Los Angeles on September 25.

According to live tracking data, an offshore sector directly off the coast of Los Angeles is currently experiencing active GPS signal disruption. Investigators are reviewing the cause of the disruption, which may have stemmed from localized ground-based jammers or military electronic testing operations. This incident was first reported by an unknown source.
