A UFO shut down 10 nuclear warheads
US Air Force veterans have been giving accounts of their alien encounters to the American Government's All-domain Anomaly Resolution Office, which has been probing UFO sightings dating back to the 1940s.
Former intercontinental ballistic missile officer Robert Salas has testified that he was on duty at Malmstrom Air Force Base in Montana in 1967 when an orange UFO briefly hovered past.
Seconds after the sighting was reported to Salas, all 10 missiles at the base "dropped offline one after the other".
Investigators were told that the nuclear weapons were "unlaunchable" and it took "several hours" to repair them again.
A probe was launched by the military at the time but no explanation was ever found for the missile shutdown.
Salas, 82, said: "I've been wanting to tell a government agency my story for over 50 years."
