Javion Hill, 35, of Kings Mountain, North Carolina, says he took several photos of the object during a storm on the night of Aug. 18, as he drove on U.S. 74 southwest of Charlotte.
The images feature something square hovering above the treeline, with its edges fringed in lights. Hill told the Charlotte Observer the craft frightened him to the point that he didn't sleep that night.
"I was on my way home with my wife on the speaker phone, and it looked like there was a tornado coming, so I was trying to take a picture of the clouds for my wife," says Hill.
"But then I saw something that wasn't normal and I was, like: 'Oh my god, what is that?' I started trying to take as many pictures of it as possible while I was driving."
Hill says he pulled over at the next exit to try and get video, but the aircraft had vanished. A heavy rain followed instantly, he said.
North Carolina is in the top 10 among the 50 states when it comes to alleged UFO sightings, according to the National UFO Reporting Center in Davenport in Washington state.
