The department's electromagnetic and laser systems expert, who has asked to be anonymous to safeguard his career, claims to have seen an extraordinary phone receiver-shaped UFO over woods in Ontario, Canada, during a hunting trip.
The man gave his account during a 40-minute interview with the Mutual UFO Network (MUFON), the world's biggest alien investigation organization.
He said he was part of a three-man team of hunters on the trip on August 28 2013 at about 9.40pm, when the "craft" was seen just 400 feet away for about six minutes.
The two other men have also not been identified.
He claims to have observed it through a rifle sight. The man gave a detailed account to MUFON.
In a video interview for MUFON, he said:
"We were driving down a logging route to the main highway when there was this craft at low enough altitude to see it through the windscreen.He described it as of "brilliant brightness" giving off as much light intensity as stadium lighting.
"I would say it was at highest 150 to 175 feet in altitude. I grabbed my rifle scope out the pack, wound the window down and hung out the open side window to observe the craft."
"I have been involved in operating systems in the past and this thing was coherent light, it was salty to the eyes to look at, like looking at a laser that had been passed through a de-fraction grading or something of that nature.The man said he made several mental notes on the object, estimating it was 170 feet long, 20 to 21 feet thick, with an outer diameter of about 60 feet.
"It was not a focused laser, it was a defocused laser.
"One of the witnesses next to me was worked up and said 'what is it?' and the other just said shoot it, but I said I can't shoot a round into something I can't identify."
"It looked as if it was made out of a forged piece of mercury. It was brilliant in polish. There were absolutely no lines, no rivets.The witness claimed that for most of the experience no cameras would work, but that after the craft got to a quarter of a mile away or more, it started to work.
"I'm a pilot so was looking for all things you would see on an aircraft, I was looking for lines in the fuselage that would indicate a door or landing equipment."
He said they were able to record an electromagnetic signature from it. But the man is not claiming it was definitely an alien craft.
He believes it could just as easily be a top-secret technology created by government departments on Earth.
DoD whistleblower scientist
He is calling for anyone who has seen a similar craft, or any advanced scientists with knowledge of high frequency radio frequency field generation systems.
"The primary reason I am doing this is I am looking for help to try to find out how this vehicle flew."The case is being investigated by the MUFON branch in Indiana, USA.
