A nuclear submarine was buzzed by an unidentified object – travelling under water faster than the speed of sound.
The claim came from a scientist who had been carrying out classified work on board USS Hampton.
Bob McGwier told fighter pilot turned UFO researcher Chris Lehto how the sub was passed at astonishing speed while it was “running deep and fast” in the late 1990s.
He said the encounter was confirmed by a member of the crew who was shocked by the speed of the Unidentified Submerged Object or USO.
McGwier told the Lehto Files YouTube channel: “We were under way and all of a sudden I hear the sound. It’s really strange because it’s clear that what is going on is something is whizzing by us and it’s moving so fast I just can’t believe it.
“This thing blew by us like we were standing still.”
He added: “A person with knowledge of onboard systems came out and said ‘this goddam thing is going faster than the speed of sound underwater – but that’s faster than the speed of sound in air’.”
