BRUSSELS (AP) — The chairman of the Joint Chiefs of Staff says the first U.S. missile fired at an unidentified object over Lake Huron missed the target and “landed harmlessly” in the water, but a second one successfully hit. The acknowledgment Tuesday by Gen. Mark Milley of the errant strike comes amid questions about whether the shootdown of aerial objects that military officials say didn’t pose a threat is creating unnecessary risk. The object taken down Sunday was the third in as many days to be shot from the skies. The White House has said the objects differed in size and maneuverability from a Chinese surveillance balloon that U.S. fighter jets shot down earlier this month
