On Sunday an octagon-shaped object was reportedly shot down over Lake Huron near the Canadian border after first being detected some 1,300 miles away over Montana on Saturday night. On Saturday a cylindrical object was reportedly shot down over Canada's Yukon territory by an American F-22, and on Friday an object "about the size of a small car" was reportedly shot down after being detected over Alaska.

Unlike the Chinese balloon that was shot down earlier this month which the US claims was an instrument of espionage, as of this writing there's still no solid consensus as to what these last three objects were or where they came from. While all three were found at high altitude like the balloon, the Pentagon is refusing to classify them as such, with the head of US Northern Command General Glen VanHerck going as far as to say it hadn't yet been determined how these objects are even staying aloft.

"I'm not going to categorize them as balloons. We're calling them objects for a reason," VanHerck told the press on Sunday. "I'm not able to categorize how they stay aloft. It could be a gaseous type of balloon inside a structure or it could be some type of a propulsion system. But clearly, they're — they're able to stay aloft."

VanHerck also made headlines for saying he couldn't rule out extraterrestrial origin for the objects.
