U̳F̳O̳ watchers are stumped after mind-blowing footage captured a strange black shape in the skies over America’s third largest city.
Aiyana, who asked that her second name be withheld, recorded the clip from the roof of her home in Chicago, Illinois, and is at a loss to explain it.
In her video, a long black wishbone shape can be seen hanging in the air, with both its wings ending in some sort of sphere.
Aiyana said: “I literally have no idea what it was. There is nothing comparable.
“It was a ball of some sort with two long strings or belts hanging from it. The strings had knobs in the middle and bottom. I felt total confusion and a bit creeped out.
“In the video, you can hear my son and me talking about it and trying to figure out what it was. Neither of us had any idea what we were seeing.”
Searching for answers, a friend of Aiyana’s shared the video with U̳F̳O̳ watchers online.
A few viewers suggested it was some kind of balloon, but nobody could explain how such a thing could float so calmly above the famously “windy city”.
One person wrote: “I’ve never seen a balloon just hang still in the open air like that. It should bob, even if just a little. There must be absolutely zero wind there.”
Another called it “bizarre”.
They wrote: “I have no explanation. It looks like something hanging from a helicopter, except there is no helicopter”.
The unexplained sighting is just one of several in the US in recent weeks.
