evidence: Some context: The US has been tracking the suspected Chinese spy balloon, which was first spotted in Montana and is believed to be moving eastward. CNN meteorologist Jennifer Gray said Friday evening that based on the wind direction, it could end up over the Carolinas or Virginia in the next 24 hours. [...] The suspected spy balloon flies over Billings, Montana on Wednesday, February 1. [...] A suspected Chinese spy balloon currently above the US resulted in an hours-long grounding of commercial flights in a swath of airspace at least 200 miles long, according to a new statement from the Billings, Montana, airport and a source familiar with the situation.
