NARRATOR: August 1946.
Esteemed US naval officer and explorer Admiral Richard Byrd,
one of the first pilots to fly over both the North and South
Poles, organizes Operation High Jump, the largest expedition
ever to travel to Antarctica, with 13 ships, 23 aircraft,
and over 4,700 military personnel.
This was very important that after the conclusion of World
War II, Admiral Byrd was asked if he
would mount a large armada and go for four months.
It was supposed to be that they would go in December,
January, February, and March.
And there was a list of military goals
that they were to achieve.
But by the end of February, something happened.
NARRATOR: One of the mission's official goals
was investigating sites for potential military bases
in Antarctica.
But during his explorations, Admiral Byrd
allegedly came upon something highly unexpected.
This story is said to come from his diaries--
not his published account of the trip,
but something he held back and then later
was suppressed by government authorities
that found it frightening.
In his diary, which was discovered by his son
after his death, Admiral Byrd tells an extraordinary story.
Admiral Byrd heard there was an entrance
to the center of the Earth through the South Pole.
And he took planes under the South Pole.
And when he did that, he discovered that as he flew
over the pole, suddenly he's looking at things
that shouldn't be there.
I mean, it was temperate.
His squadron flew under the Earth, into the Earth.
It turns into this lush and green area,
and he can't even believe his eyes.
But that's just the beginning of his extraordinary story.
He tells how all of a sudden he starts
to see a shimmering rainbow city that's made of crystal.
His airplane is taken control of when he suddenly
sees these flying disk-shaped objects around them that lead
him to the ground, whereupon he's escorted
into a cavernous type of an area where
he meets a being he refers to as "the master" in his diary.
The master tells him that they're
highly disappointed in what humans are doing
with nuclear weapons and how they've recently destroyed
Hiroshima and Nagasaki, and they really
are concerned about what is going
on the surface of the planet.
They tell Admiral Byrd that they hope that humanity
will ultimately stop this.
NARRATOR: For UFO researchers, this account
from Admiral Byrd's diary is particularly significant due
to the fact that the modern UFO era began right
after World War II and the detonation
of the first atomic bombs.
It has also been noted that a high number of UFO sightings
have been reported in the vicinity
of nuclear missile silos.
Admiral Byrd's story is congruent with the stories that
we hear from numerous accounts of angelic
or extraterrestrial-type beings that are
very concerned about what humanity
is doing with nuclear weapons.
Just ask the Air Force officers at the US missile
silos, the nuclear missile silos,
that have seen their silos and their nuclear arms
disarmed by what are perceived to be extraterrestrial beings.
They are very concerned that we are ultimately not just going
to destroy ourselves, but could harm our planet,
which is their world as well.
NARRATOR: If Admiral Byrd's secret diary is authentic,
does it reveal not only that there are highly advanced
beings living inside the Earth, but also
that they are monitoring what happens on the surface?
According to the diary, after this incredible encounter,
Admiral Byrd was eager to share his story,
but was ordered to remain silent.
Byrd comes back after this experience.
He is taken to a government compound, where he is told
that he is never to speak of this publicly
and that everything he says is classified.
NARRATOR: Could Admiral Byrd's story point
to a profound connection between the ancient traditions
of strange beings living inside the Earth and
the modern-day UFO phenomenon?
Ancient astronaut theorists say yes
and believe we may be fast approaching the time
when we will find ourselves face to face
with the beings of inner Earth.
