GETTYMarc D’Antonio claims that USOs are common
Marc D’Antonio is an astronomer and chief video analyst for the Mutual UFO Network (MUFON) organisation.
He claims that while he was on board a US submarine in the North Atlantic Ocean he saw an alien craft travelling at impossible speeds - an unidentified submerged object, or USO.
He said: “As a thank you for doing some work for the Navy, they asked me if I wanted to go for a ride in a submarine so I said yes.
“Once we got under I was sitting in the sonar station and the sonar operator was sitting right next to me.
"Submarines are loud – people think they are very quiet and it’s true they are on the outside because the sound doesn’t get out. But inside you hear fans, noise - it’s a constant din on a sub.
“I was sitting there zoning out a little because I was seasick and all of a sudden the sonar kid shouts 'fast mover, fast mover'. I’m jolted awake thinking ‘what’s happening? Is it a torpedo?’
“The executive officer comes out, the operator shows him the path of the object and the officer says 'How fast is that going?'
“And the kid said 'several hundred knots'. I start to lean forward to listen in and the officer said ‘can you confirm it?’
“So he goes to another sonar machine and confirmed it wasn’t a machine anomaly, it was real. I thought ‘wow that is incredible’.
“When the sonar guy said ‘what do I do with this?’ the officer said ‘log it and dog it’ - in other words, log it and bury it.”
Mr D’Antonio said he spoke to a senior naval figure about what he saw four years later.
He added: “I asked him ‘Can you tell me about the Fast Mover Programme?'"

“He looked at me and said 'sorry Marc I can’t talk about that programme'.
“So he basically confirmed to me that the programme exists - he said everything without seeing anything.
“What that told me was that USOs are common. We even have a programme in place to classify, log and determine the speed of them and it goes into a vault.”
GETTYThe findings were revealed at Devil's Tower
The claims were revealed at Devil’s Tower UFO Rendezvous in Hulett, Wyoming, an event where Ufologists meet at the site where Close Encounters Of The Third Kind was filmed to discuss alien findings.
He also revealed that he is working on a project with Close Encounters effects supervisor Douglas Trumbell to scientifically prove the existence of alien life.
They are designing UFO detecting ground units which will combine science and standard observation by collecting sightings in a database and alerting the presence of UFOs via GPS.
MUFON is an American non-profit organisation that investigates UFOs and is one of the oldest and largest UFO-investigative organisations in the US.
