Shaneika Joyner and six-year-old India filmed the bizarre ‘UFO’ while waiting at a set of traffic lights in South Carolina.
The pair were driving on Highway 52 in Goose Creek when they spotted a small dark grey object floating in front of them.
Shaneika managed to capture footage of the peculiar item flying through the sky.
In the clip, taken on July 1, India can be heard saying “oh my god, is something in there?” as the shape drifts above the signals ahead.
The child then asks: “Is it a ship?” as the object, darker than the clouds behind it, appears to twist in midair before disappearing behind some trees.
Stay-at-home mum Shaneika, 41, said she had “absolutely no idea what it was”.
“India asked if it was a ship when she first saw it fly past,” she said.
“It was going fast but it slowed down enough for me to record it. It looked like it spun a little when it got by the trees.
“In my 41 years on this planet I have never seen anything like it before. I was in awe.”
Shaneika said the object was visible for “less than one minute” and was actually one of two, but she “couldn’t keep eyes on them both at the same time”.
She added: “At first I thought it may have been a plastic bag but I was like, that’s too fast and too high.
“Some people have said it’s a balloon or a trash bag. However, some have said they believe it’s a cloaked ship.”
Shaneika’s footage sparked debate after being uploaded online, with speculating commenter’s explanations ranging wildly.
One person said: “Drone with cloaking tech.”
Another asked: “Lower atmospheric cloud caught in a back-wind?”
However, one commented: “That’s a damn plastic bag.”
