In the midst of the Cold War on several occasions, nuclear missiles at US Air Force bases were mysteriously shut down, according to US servicemen who said they witnessed the failure of the heavily guarded missile systems.
But they don’t blame America’s Cold War enemy, the Soviet Union; they say aliens from space did it.
“This was something Russia could have developed, but it turns out they didn’t develop this and we don’t have it either – to be able to shut down nuclear weapons with a beam of light,” David Scott, a former sergeant in the US Air Force, told RIA Novosti at a conference in Washington on encounters with extraterrestrials.
Scott and three retired Air Force officers told a panel of six former members of the US Congress at the conference about their experiences with extraterrestrial “visitors” who meddled with US nuclear weapons systems.
