A butterfly shaped UFO which was allegedly captured on film and posted online has produced huge excitement in the UFO research community.
The unusually shaped black craft was recorded by a father and son who were leaving a restaurant near the Kentucky/Ohio border in the US.
Tom and his son Christopher told local media that two "military helicopters" flew over the area just five minutes later.
Small flashes of light can be seen twinkling on the underbelly of the craft as it nears the horizon.
Photographs of the alleged incident also posted online by Tom and Christopher show bright lights on the underside of the object.
The footage was released by YouTube channel 'Secureteam10' which has been previously been accused of adding computer generated imagery (CGI) to video clips.
Tyler Glockner, who manages the channel, denies these accusations and maintains he is a genuine alien researcher.
"The reason I am calling this an alien craft rather than just a UFO is because of the stunning detail, where we can see the true structural characteristics of this ship.
"And guys you take a look and tell me with a straight face this has anything to do with humans.
"The features on this thing don't make any sense," he said of the mysterious object.
The video has been viewed by more than 1.1 million people.
