US military shoots down fourth flying object over North American airspace

Incident involved third unidentified object downed by US and Canadian jets in recent days, and follows shooting of large balloon claimed by China

The US military shot down a fourth flying object over North American airspace in a week on Sunday over Lake Huron in Michigan, confirmed the state’s governor, Gretchen Whitmer.

The high-altitude unidentified object was the third to be downed by US and Canadian fighter jets in as many days, starting with a vessel about the size of a small car off the coast of Alaska on Friday, followed by a similar flying object over Yukon in Canada on Saturday. On 4 February, a large balloon which has been claimed by China was shot down off the coast of South Carolina.
