Why? The answer is very simple. A UFO is an Unidentified Flying Object. That's it. Thats the definition, that is the final answer. A UFO is not an alien spacecraft, or swamp gas, or any of the other explanations given. If a UFO was in fact an alien spacecraft...then it wouldn't be unidentified then would it?
Thanks to many movies, and TV shows, UFO is now synonymous with Flying Saucer. And that's just wrong. It means the words themselves have been corrupted by media and others (on both sides of the fence mind you). I don't know exactly why this is, but it's happened, so we have to deal with it now. Personally, I've been ridiculed for believing in UFOs, until I explain WHAT a UFO is. Most people have the wrong definition in their head. Though many know what UFO stands for, they don't seem to make the connection that if it IS a UFO...it's really just a label for "I don't know". Again, if it WAS an alien spacecraft, that is an IDENTIFIED object. The SR-71 Blackbird was likely the cause of many UFO claims in the 60's before the US acknowledged it's existence. Now that we have more info, more cases can be put to rest. There is still at least 10% of sightings that go unexplained, be it from lack of information, or unrelieable witnesses.
There is a new term that has been floating around for a while, and people who are serious in this field should 'probably' start using this one. In reality, there isn't much difference between the two. As opposed to UFO, people are starting to use the term UAP. Unidentified Aerial Phenomenon. The only real change is taking the "flying" out. Phenomenon and Object are basically the same thing in this use of the word.
Using UAP instead of UFO would maybe lead to a better field of research in this area, since, your at least not starting off with "Flying" in the title, which is probably what puts most people off. Plus, Aerial Phenomenon is more broad ranging than Flying Object. AP's could be anything, cloud formations, swamp gas...basically, everything that has been explained as a debunked UFO...is an AP...but...an IDENTIFIED aerial phenomenon. There is still so much we do not know of this world, new things are being discovered daily.
At a certain point, more people will come to realize that we are not alone in the Universe. I don't know what's out there...but I'd sure like to see it some day.
I currently have a UFO/UAP that I'm trying to identify. It's posted below with a link to the other photos in the set. Please see notes with the photos for sequence of events that day. If you have comments or questions, leave them!
