Two times during the weekend, U.S. fighter jets were deployed to intercept civilian planes flying over Palm Beach, Florida, where President Trump was staying at his Mar-a-Lago estate. According to the North American Aerospace Defense Command (NORAD), the most recent event took place around 1 p.m. on Sunday. NORAD planes were required to accompany a civilian aircraft out of the restricted area after deploying flares to attract the pilot’s attention. It is important to note that the airspace above Trump’s property is under a continuous flight restriction, with a radius of 30 nautical miles expanding when the president is present at the estate. NORAD said its aircraft have responded to more than 20 “tracks of interest” since Trump took office on Jan. 20. The agency reported three interceptions just last week. The military command reminded pilots to stay current on the “Notice to Airmen,” or NOTAMs, issued by the federal government, which include Temporary Flight Restrictions, or TFRs. “The excessive number of recent TFR violations indicates many civilian aviators are not reading” the notices, Air Force Gen. Gregory Guillot, Commander, NORAD and U.S. Northern Command, said in a news release. Sunday’s incident took place as Trump finished a round of golf at his West Palm Beach golf course. Jets also conducted an intercept on Saturday morning shortly after Trump arrived at the course from his private Mar-a-Lago club and residence. Trump’s schedule was not affected over the weekend, officials said. The Associated Press contributed to this report.
