NORAD says it has "detected a small balloon at an altitude varying between 43,000-45,000 ft. The balloon was intercepted by NORAD fighters over Utah, who determined it was not maneuverable and did not present a threat to national security. NORAD will continue to track and monitor the balloon. The FAA also determined the balloon posed no hazard to flight safety. NORAD remains in close coordination with the FAA to ensure flight safety.”

A US official confirms to VOA News the balloon does not appear to be a threat.
