Sports writer Mike Sewell made the claim during an interview with Radio 5 Live, the Daily Mail reports. Sewell said he spotted a huge "disc-shaped" object hovering above the countryside in Hertfordshire while on his way to work.
Sewell was driving from his home in the Midlands to catch an early morning flight from Stansted airport when he saw the UFO in the sky over the village of Cottered, near Buntingford, he claimed.
"I was probably about 15 or 20 miles from Stansted at 4:15 in the morning and there was this big bright light in the sky descending towards the road," Sewell said. "As it got closer it then banked to the left, and as it banked to the left and went across the countryside I could see underneath it.
"It wasn't an airplane, and it wasn't a helicopter. Certainly of a kind of -- and I dread saying this -- disc shape. It had several lights flashing all around it."
The well-respected reporter said another driver nearby also saw the UFO.
