In East Antarctica, a team of scientists drilled a hole in the Vostok ice sheet to take a sample of the subterranean lake 2.2 miles below the surface.
It was the deepest drill ever performed through ice anywhere in the world.
When the results of the core sample were published, it was highly scientific, and revealed a unique snapshot of the Earth's atmosphere 15 million years ago.
Within hours, elite military teams from the U.S., Great Britain, Russia, and Australia had converged on the site - which meant somebody had revealed what they had really discovered buried beneath the snow...
Something that the world was never meant to know.
