On Wednesday morning, a United Airlines pilot reported a potential collision with a drone while approaching San Diego International Airport. The incident occurred during the descent of a Boeing 737 flight from San Francisco, at an altitude of approximately 3,000 to 4,000 feet, which is well above the federal altitude limits for drone operations. The pilot described the drone as a small, shiny red object flying westward. Despite the reported encounter, the flight, which had 48 passengers and six crew members, landed safely, and maintenance crews found no damage to the aircraft. The Federal Aviation Administration (FAA) stated that no other pilots in the vicinity reported seeing a drone during the incident. Drone operations near airports are heavily regulated, with strict altitude and distance limitations to ensure safety.
