The US Federal Aviation Administration briefly closed airspace over Lake Michigan on the border with Canada. The department told AFP that this was necessary to “support the activities of the Department of Defense.”
It is not specified what kind of activity the Pentagon is talking about. The airspace is now open again.
The US air regulator made a similar decision earlier on February 12: the airspace over the state of Montana on the border with Canada was partially closed. The North American Joint Aerospace Defense Command explained that it had found “an anomaly on the radar”, but the check did not reveal any suspicious objects. Shortly before this, US and Canadian aircraft took to the skies to destroy an unidentified object in northwestern Canada.
In the United States and Canada, three objects invading their airspace have already been shot down. In the United States, two balloons were destroyed, at least one of which belonged to China. Ottawa did not specify which and whose object was shot down over Canadian territory. According to media reports, we can also talk about a balloon.
