Just out and reported by CNN, what is believed to be a Chinese surveillance balloon is crossing the USA. At the moment the decision has been made not to try to bring it down. I'm sure there'll be more said about this in upcoming days ...and the conspiracy theories will probably follow.

The US is tracking a suspected Chinese high-altitude surveillance balloon over the continental United States, a senior defense official said on Thursday.
The Pentagon has been tracking the balloon for several days as it made its way over the northern United States, Pentagon spokesman Brig. Gen. Patrick Ryder said.
“We are confident that this high-altitude surveillance balloon belongs to the [People’s Republic of China],” the senior defense official said. “Instances of this activity have been observed over the past several years, including prior to this administration.”
