A high altitude balloon floats over Billings, Mont., on Wednesday, Feb. 1, 2023. The U.S. is tracking a suspected Chinese surveillance balloon that has been spotted over U.S. airspace for a couple days, but the Pentagon decided not to shoot it down due to risks of harm for people on the ground, officials said Thursday, Feb. 2, 2023. The Pentagon would not confirm that the balloon in the photo was the surveillance balloon. (Larry Mayer/The Billings Gazette via AP)
