There is no safe place. Every day, all around the world, in the most ordinary places, regular people are spotting UFOs. A day trip to the beach…a walk in the woods…an after work drink on the back porch…these very common moments become the point of entry for the most inexplicable, otherworldly and terrifying phenomena. Whether they are lights in the sky, multiple objects flying in tandem or craft that travel and maneuver in ways that defy our understanding of physics, lives are changed forever in these moments. These witnesses will never see the night sky the same way, ever again – and neither will viewers.

It’s the worst case scenario imaginable. When your day job involves the oversight of missile silos, nuclear facilities or a military base, the last complication you want to deal with is a close encounter with a UFO. Here’s the bad news: UFOs seem to be seen at these vital sources of power and defense more than anywhere else. Here, an already frightening phenomenon turns positively chilling for the eyewitnesses involved: a mystery colliding with our national security and the well being of our entire species.

Sometimes, the mysterious unidentified objects people see in our skies touch down to Earth leaving physical evidence behind. Are these attempts to communicate? Scientific studies by extraterrestrials? The next inevitable step toward contact? This evidence takes many forms and is as perplexing as it is all consuming. Visitations that leave behind metal objects, radioactive landing sights or witnesses traumatized and sick give us fascinating, tangible evidence. With these visitations come questions: what do they want and how long have they been here, among us on Earth?

A UFO detected on military radar, landed near crucial NATO bases. Around 3:00 am on December 26th, a security patrol near RAF Woodbridge spotted descending lights. Servicemen – Jim Penniston, John Burroughs, Ed Casabang – investigated, finding a glowing metallic object with colored lights. It moved through trees, agitating nearby farm animals. Penniston documented the craft for 45 minutes in a notebook, including sketches of hieroglyphic inscriptions. Deputy base commander Lieutenant Colonel Charles Halt and team, armed with an AN/PDR-27 radiation meter, visited the site next day. Radiation readings were taken in the depressions’ triangle and surroundings. Halt recorded the events on a micro-cassette recorder famously known as “The Halt Tape”.
