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.
