Two top gun pilots have been filmed giving chase to a UFO over a park full of tourists.
Alex McCall was with his school teacher daughter and grandchildren when the military jets blasted across the skies at high speed.
But they then looked up to see the unidentified flying object in front of them.
Alex's daughter was able to film the eerie moment on her iPhone as they roared over Acadia National Park, in Maine, USA.
The two military jets then vanished into the clouds.
Former pilot Alex said he was convinced from his 25 years of flying thay the white, Tic Tac-shaped UFO could not have been another plane.
He said: "My daughter took the video. It's legit, we don't know what it is.
"There are people saying it's CGI that are obviously clueless.
"She stopped filming when she couldn't see them anymore. It was taken with an iPhone.
"We were on vacation in Maine. There were dozens if not hundreds of people around.
"My kids and grandkids saw it and then heard it. My daughter got her phone out and on and pointed in the right direction but couldn't tell if she was getting video of it.
"She stopped when she couldn't see them any longer."
Alex said they weren't the only ones to witness it.
He added: "One person said his mum got a good video of it.
"It all happened so fast.
"You can hear my grandson say he likes jets. Everyone thought the white thing was another airplane until I looked at the video."
The video - filmed on June 20 - has only just come to light.
It's not the first time Alex has encountered a UFO.
"I saw a UFO in 1996 and know what I saw. Unfortunately I didn't get a picture of it," he said.
"The reason I know there is something to some of the sightings is because I saw exactly the same thing.
"Up close and personal. I don't have a clue what those jets in my video are with but I do know it's not another fighter jet.
"I also know it wasn't faked. For what it's worth, I was an airline pilot for 25 years."
Last year the Pentagon confirmed the authenticity of an in-flight video showing a Tic Tac UFO filmed by a US Navy F/A-18 Super Hornet pilot from the USS Nimitz off the coast of Mexico.
