Triangular UFOs: An Estimate of the Situation

Rate this book
For years, serious researchers have known that triangular-shaped UFOs are one of the most common types observed. The phenomenon has sparked intense debate among many and excited the imagination of many others. But until now, there has never been a book-length treatment of this fascinating subject.Finally, we have one. David Marler has provided a comprehensive analysis of “the triangles.” He has collected, collated, and analyzed hundreds of reports. In the process, he has created a detailed profile of these objects and written a rich narrative of their history.Marler is well-suited to the task, having at his disposal an enormous collection of newspaper archives, declassified military reports, UFO books and journals, and the transcripts of many first-hand interviews he has conducted. He has also received input from many prominent individuals from within the military, FAA, Aerospace, and UFO research field.He tackles the arguments made by skeptics that dismiss these triangular UFO reports outright. He also address the claims of so-called insiders who claim these objects are a creation of the U.S. military.The results of his years of research are documented in his book, Triangular An Estimate of the Situation. It is a book that has long been needed, not only by the UFO research community, but the general public, as it opens up an entirely new discussion that has long been who is making the triangles?

Fascinating, Jim. Seriously, this is fascinating stuff and what's been observed in the 11,000 documented sightings up until 2013 has been fairly consistent. I know someone who has seen this triangular vehicle and thinks it belongs to British Aerospace as it came from the direction of their site, but there have been reports of what might be the same model appearing since 1882, before the Wright Brothers flew. Although, there has been a massive uptick in the slow, quiet triangle being seen since the 1980s. 2,742 reported it from 1882 up to 2004 and then about 8,250 reported it in just 9 years between 2005 and 2013 (always at night, most frequently in the UK and US, but also in two other NATO countries). Now I've done my journalistic homework, I think I should make an effort to interview people who have seen it.

This is an excellent survey of the Triangle UFO phenomenon. And it goes back a lot farther than I originally thought. My knowledge said that the 1970s saw our first sightings. But Marler shows that sightings of this particular design go back to at least the late 1800s. And after surveying a select, but solid, list of reports, we come down to the primary characteristics that span them all regardless of time frame:

Beams of light emitted (as if searching for something), three bright lights (one at each point), large in size, ability to hover, ability to make flat turns, silent in flight, slow speed, low-altitude flight, sharp turns at high speeds, and rapid acceleration. Secondary characteristics are also examined but this is enough for our review.

Now for me, I've always assumed that what people were seeing with triangles was experimental stealth bombers, Skunk Works stuff. As I said, I was under the impression the triangle made its appearance during very human secret testing of the stealth. But, as noted, Marler shows us these “ships” go back over a hundred years and demonstrate the same characteristics. So what followed in the book after the examination of said characteristics was my favorite part.

Chapter 8: Aerospace Experts.

A valuable interview between Marler and Professor John E. Allen is within. Now retired, he's basically the guy with decades of aerospace experience you want to talk to about flying triangles. The summary of the interview is that to this day (published 2013), we have no ships or technology that can do what these triangles are reported to be doing. Nothing today exists in our current technology that can match the primary characteristics of these triangles. Dr. Allen is left with simply saying he's open to further study but seems certain most, if not all sightings, are simply mistaken observations.

But if Dr. Allen is right, how come we can pin-point similar characteristics? Are we to think everyone for the past hundred years saw something in the sky with the descriptions? If there is nothing tangible in the sky regarding this but people worldwide are reporting them using the same explanations, it says something about the human brain that begs for examination. Jungian archetypes anyone? But that wouldn't explain multiple people seeing the same thing.

I was left with this volume where I usually do with most others. This is interesting stuff and makes me keep reading and searching the skies. But we're dealing with anecdotal information and that is not scientific. Despite all these years of triangle reports, why do we have almost no pictures? No video? No pieces? (None that can pass the hoax test). Marler acknowledges this. It was even telling there were no photographs in the book, only drawings. Granted, it's only been about ten years just about everyone had a device in their pockets to whip out at a moment's notice to capture a photo. Maybe some are coming? Even so, I'm afraid the field is so plagued with hoaxes and photoshopping we'll never believe it even if the genuine thing shows up.

In his conclusion, Marler notes, “These triangular UFO reports are not ambiguous, like the majority of UFOs over the years, involving simple 'lights-in-the-sky'. These are apparent structured craft of appreciable size. They appear to defy physics as we know it. The over-all consistency in reports over decades indicates a specific subset of UFOs (triangles).”

I admit, this is impressive. The evidence in this book would persuade a jury in a legal trial. But that's not enough for a scientific conclusion. Thankfully, Marler acknowledges this. Because the same could be said about Bigfoot. So until we get something beyond anecdotal reports, more sightings will give us nothing more than we already know. I highly recommend this book. It's the best we're going to do until better evidence comes forth to prove tangible triangles in the sky. I'd like to think it will. One can be hopeful.

Well worth reading

Nuts and bolts reporting of a manageable sub-set of the phenomena, refreshingly free of the "nuts" aspects so prevalent with speculative and conspiracy theory driven works. Avoid the rabbit hole and stick with credible, corroborated sightings. It's been noted that 90-95% of sightings are crap. Ufology books are pretty much the same. If I find a good one, I let people know.

This is a book where a lot of research was involved. There is a great collection of sightings here. What I could say to the author is, that the other events in the UFO lore are not bunkers or crazy, that is the same treatment skeptics treat the subject. The patterns actually add up when put together. Open minds are important to get to the bottom of it.

Very thorough research! Mr Marler is very careful to present the facts, not theories. I was surprised to find out that sightings of triangular craft go back to the 1950s.

Many, many, many new sightings of triangular UFOs!

The author does not go into very much detail on these sightings, but that's okay. You gather so much information as it is, its nearly overwhelming!

The author's discussions are thought provoking. I will definitely re-read this awesome book again and again
