Pilots Advised Of Large White High-Altitude Balloon East Of Hawaii (Updated) The balloon was supposedly called-out by the FAA as being roughly 600 miles east of Hawaii at between 40,000 and 50,000 feet.
According to multiple reports, the FAA notified pilots of a sighting of a large white balloon at between 40,000 and 50,000 feet roughly 600 miles east of the Hawaiian Islands. Subsequent ACARS (Aircraft Communications, Addressing and Reporting System) messages show aircraft in the area — which is normally quite busy as it sits on the route from the U.S. west coast to Hawaii — acknowledging the alert, which includes a request to report back if they spot any such object.
