UFOs once appeared to disable the nuclear missiles being housed at a US airbase, a politician has claimed.
Tennessee Republican Tim Burchett claims he received the bombshell information just as two other officials denied while being questioned that it was being looked at by the Unidentified Aerial Phenomena (UAP) task force.
Congress recently held a public hearing on UFOs with key witnesses Scott Bray and Ronald Moultrie.
Both Mr Bray, deputy director of Navy Intelligence, and Mr Moultrie, undersecretary of defence for intelligence, claimed that the UAP task force has not looked at the alleged incident.
Rep. Burchett told The Sun Online as the pair were speaking, he received a message saying it wasn't true.
He said: "The interesting thing is that I received a text at that time from somebody in the know.
"And that said 'in fact, they’re not telling the truth – this a documented thing. I’ve seen the file on it – it’s there, it exists. They’ve either not been shown it or they’re lying."
During the hearing, Mr Bray was asked about the reports about UAPs flying over "sensitive military facilities housing our nuclear forces".
He said: "One such incident occurred at Malmstrom air force base."
Tennessee Republican Burchett said if Congress is serious about getting to the truth then the pilots who witnessed these UFOs need to testify.
It comes as a former US Air Force captain has said his team saw a giant UFO disable 10 live nukes at a top-secret base in Montana over 50 years ago.
Captain Robert Salas was the on-duty commander of a secret underground launch control facility when the alleged incident happened on March 24, 1967.
He said he was in charge of ten nuclear missiles and was 60ft underground when a UFO came over and hovered the facility.
The captain said all the guards saw the UFO and reported the incident to him - and then the missiles were mysteriously deactivated.
Captain Salas said: "While the object was up there we lost all ten missiles due to guidance and control failure."
Salas, who was then a Captain, said the bizarre incident unfolded in, 1967, while he was the on-duty commander of a secret underground launch control facility at Montana’s Malmstrom Air Force Base.
He added it was impossible that the ten nuclear missiles shut down at the same time because they were all running on independent systems.
