The Chinese balloon, which Beijing denies was a spy vessel, spent a week flying over the United States and Canada before President Joe Biden ordered it shot on Feb. 4. China says the balloon shot down on Feb. 4 was a civilian weather-monitoring aircraft. It has accused Washington of sending its own balloons into Chinese airspace, an allegation Beijing reiterated on Tuesday. 'COMMERCIAL OR BENIGN PURPOSE'The U.S. military said on Monday it had recovered critical electronics from the suspected Chinese spy balloon as well as large sections of the vessel itself. But it has not yet recovered debris from the most recent three objects shot down, with tough weather conditions making recovery operations difficult.
