2023 Alaska high-altitude object

On February 10, 2023, the United States Air Force shot down a high-altitude object that had entered U.S. airspace over Alaska a day before. The object was shot down onto the Beaufort Sea. The Department of Defense said it was the size of a small car and flying northeast at approximately 40,000 feet (12,000 m), posing a risk to civilian flight. On February 16, 2023, US President Joe Biden stated that the downed object was probably a civilian-owned balloon and "most likely tied to private companies, recreation or research institutions".
