Encounter: Ufo, Security Threat

There is no safe place. Every day, all around the world, in the most ordinary places, regular people are spotting UFOs.

When your day job involves the oversight of missile silos, nuclear facilities or a military base, the last complication you want is a close encounter with a UFO...

These are first-hand experiences of the most terrifying kind: stories shot through with mystery, fear and endless questions.

Being on an aircraft that comes in close proximity to an object that doesn't appear on radar is a scary experience. Who are they and what do they want?

UFO sightings are at an all time high. What makes these mass sightings incredible is also what makes them terrifying, and what might happen next?

Sometimes, the mysterious unidentified objects people see in the sky touch down and leave physical evidence behind.

They keep coming back. There are areas around the world that seem to keep attracting UFOs, where objects return to the skies again and again, as if taunting witnesses below.

These are the witnesses that have been literally touched by the unknown. Do these cases hold the answer to the central question of UFOlogy?
