Just who owns it and where it is destined remains a mystery.
Fox News reports the DoD and Federal Aviation Administration (FAA) first detected and tracked the unmanned balloon off the coast of Hawaii on April 28.
It was floating at about 36,000 feet, a DoD spokesman said.
When the balloon crossed into U.S. airspace over Hawaii, it did not transit over critical infrastructure used for defense or any other U.S. government sensitive sites, the spokesman said, nor did it pose a threat to the military or those on the ground.
