Chinese spy balloon in Montana. A Chinese surveillance balloon is hovering over the western U.S. state of Montana in an attempt to collect intelligence “right now,” U.S. officials said on Thursday. While the balloon is floating in airspace high above commercial aviation traffic and is not dangerous to people on the ground, defense officials are monitoring it closely and briefly considered shooting it down before deciding that would be too risky. The rural area where it was spotted is home to several U.S. military installations, including Malmstrom Air Force base, which houses intercontinental ballistic missiles.

The diplomatic consequences could be significant. The announcement came just hours before Secretary of State Antony Blinken was scheduled to depart on a visit to China, where he is planning to meet President Xi Jinping. “The decision to publicize the discovery appears to put China on notice ahead of Mr. Blinken’s Beijing visit … The sudden appearance of the balloon is bound to raise already escalating tensions between the two powers,” the New York Times noted.
