When UFOs Act Hostile | Close Encounters 212

Go head-to-head with an aggressive, barn-size UFO that swoops down on a teen trying to thumb a ride. Then meet a retired French engineer who gets close to a crashed flying saucer before it tries to scare him off with a bizarre, high-pitched whistle.

B-52 vs B1-B Survival of the Fitness, and Oldest

Join Outskill’s two day AI Skills weekend here and get $5000 of bonus material https://link.outskill.com/CURIOUSDROIDMAR4
The B-52 and B1-B bombers are still the heavy weights when it comes strategic bombers. One comes from the 1950s and one from the 1970s, both are old air craft and yet they are all over the news. But how did the two old aircraft become the default when much new versions should by all right be in their place. In this video we look at why there made and why they are still here and what comes after.

UFOs in the Most Unexpected Places | Encounter UFO 101+102

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.

Oumuamua: Why This Object Shocked Scientists | Encounter UFO 106

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?
