On September 4, 2026, San Diego International Airport temporarily halted operations following multiple pilot and air traffic control reports of unauthorized drones and a high-altitude balloon near the airfield. Recently released FAA records, obtained via a Freedom of Information Act request, confirm that military personnel were notified and prepared to engage an unauthorized drone, with air traffic control audio referencing a potential shootdown. While the incident caused significant flight delays, the exact identity and origin of the objects remain under investigation by authorities.
