Your expert UFOlogists, of which I am not one, will tell you that among the recurring type of Unidentified Aerial Phenomena that are most commonly spotted are your glowing orbs, the prototypical "saucer" craft such as this:
… what's described as a glowing cube inside a transparent sphere, and solid, metallic triangles with lights along the sides, as in the illustration above.
And that last type was just captured on video hovering above Indiana:
MSN - “Flying Triangles” or “Black Triangles” are one of the more commonly seen types of UFOs. They’ve been reported all over the world for as long as folks have been reporting UFOs. The reports all bear a striking similarity: enormous, silent black triangular craft that hover mysteriously in the sky. They move slowly, with no visible means of lift or prolusion, and can also zip away at near-instantaneous speeds. … They like to show up at military bases or in populated areas, and just hang in the sky, as if observing whatever is going on down below.
Indeed, one of the most interesting facts about these types of UFOs is that they do not exhibit Andy cloaking ability or evasive actions.They don’t seem to care that we see them.
This sighting, in Indiana, is of a massive triangle with blue lights that appears to just be hanging in the sky.
The family, driving along back roads, spotted the object through their car window, and filmed it for several minutes.
Some people, upon viewing this video, said it’s nothing more than holes in the clouds of the overcast sky, but they are remarkably even ones to form this perfect triangular shape, and the light shining through is very bright indeed.
Yup, that's it alright. Just another one of those overcast skies where the clouds get circular, bright blue holes in them, lined up to form perfectly symmetrical triangles. Who among us hasn't see that? It happens practically every cloudy night.
Sarcasm aside, this is, like I said, among the most common UFO types spotted. Most famously - or infamously - the "Phoenix Lights" incident from March of 1997:
Wikipedia - Lights of varying descriptions were seen by thousands of people between 7:30 pm and 10:30 pm MST, in a space of about 300 miles (480 km), from the Nevada line, through Phoenix, to the edge of Tucson. There were two distinct events involved in the incident: a triangular formation of lights seen to pass over the state, and a series of stationary lights seen in the Phoenix area. The United States Air Force identified the second group of lights as flares dropped by A-10 Warthog aircraft that were on training exercises at the Barry Goldwater Range in southwest Arizona. Witnesses claim to have observed a huge carpenter's square-shaped UFO, containing five spherical lights or possibly light-emitting engines. Fife Symington, the governor of Arizona at the time, years later said he witnessed this incident, describing the object as being "otherworldly."
Yeah, about that. First of all, the thousands of people who observed these phenomena called bullshit on that "flares" explanation because what they saw wasn't just lights; it was a solid object with lights on it. Also, the lights didn't simply fall like flares would. They stayed in formation, hovering and moving together, like they were all attached to the same craft. Because they were. And also, why would the USAF be dropping flares over urban areas when they've got thousands of square miles of desert to practice in? Lastly, Fife Symington did nothing but piss off the entire UFOlogy community by calling a press conference where he was going to speak on the record about what he saw. Only to have some aid come out in stupid Spirit Halloween alien costume and make a big joke out of it. It was only years later when he admitted to seeing the same things as the thousands of his taxpaying citizens that he mocked with that goofy, pointless stunt.
An earlier incident took place at the RAF Rendlesham Forest air base in Woodbridge, England. Often referred to as "Britain's Roswell, a triangular UFO actually landed and was investigated by officers of both the RAF and the USAF. Some claimed to have been close enough to touch it and see markings on its side. Later research found imprints in the ground from three landing gear, all of which were emitting signatures of radiation.
Again from Wikipedia - The UK Ministry of Defence has stated the event posed no threat to national security, and therefore, it was never investigated as a security matter. Sceptics have explained the sightings as a misinterpretation of a series of nocturnal lights: a fireball, the Orfordness Lighthouse and bright stars.
As both these stories demonstrate, our government and those of our allies used to be willing to say anything, no matter how ridiculous, to try and make these stories go away. The thought of our best and brightest personnel, who have dedicated their lives to air defense, not being able to tell the difference between a thing they saw and approached sitting on the ground and a lighthouse or some stars is even dumber and less imaginative than talk about signal flares. Or online comment sections droning on about holes in clouds. Eventually their lies started to sound more preposterous than the truth.
Which is these things are up there. They don't care that they're being detected. And we are getting more and better images of them almost daily. Our governments are slowly admitting it. It's time the rest of us stop denying the evidence and admit it too.
