As the fear of UFOs grips the United States, the Federal Aviation Administration ordered the airspace over parts of Lake Michigan to be closed temporarily on Sunday. The latest development came after a cluster of 20-30 balloons was seen flying over the area in the skies.

Photos and videos of the balloon cluster were posted by a Twitter user named Patrick J Forkin, who wrote in the caption: “Spotted over Lake Michigan in Chicago. A cluster of 20-30 balloons floating around. #faa #lakemichigan #chicago #ufo #baloon.”
