China launched a high-altitude balloon from Hainan, originally intended to pass over Guam and Hawaii. Prevailing winds diverted it off course, carrying it across Alaska, western Canada, and the contiguous United States. The U.S. government had been tracking the balloon since its launch, while China maintained it was a civilian meteorological airship blown off course.
From January 28 to February 4, 2023, the balloon traversed North American airspace before the U.S. Air Force shot it down over territorial waters off South Carolina near Myrtle Beach. Debris was recovered and analyzed by the FBI. Officials determined the balloon carried intelligence-gathering antennas and equipment, though its sensors were never activated over the continental United States.
The incident heightened U.S.–China tensions, with the United States declaring the balloon a sovereignty violation. Secretary of State Antony Blinken postponed a planned diplomatic visit to Beijing, and Canada summoned the Chinese ambassador. Forensic analysis confirmed no intelligence was transmitted to China. Three additional high-altitude objects were subsequently detected and shot down, though later deemed unrelated to China.
