A shocked witness stared in disbelief as they watched a UFO apparently being transported by a police convoy on the back of truck.
The anonymous witness said the lorry was driving near top-secret US Airforce Wright Patterson USAF (WPUSAF) base, which is believed to be one of several military bases where the authorities store alien UFOs.
The alleged sighting came to light after the man reported it to the National UFO Reporting Center (NUFORC).
Footage shows several police cars driving past before a lorry comes into shot - carrying what looks like a "flying saucer" - in the Fort Leonard Wood area of Missouri on February 1 at 10.15pm local time.
