The glow on the left is not the UFO. That's a street light. The blue orb in the center of the screen is the UFO. As is always true with night imagery, it's impossible to tell much except that the light is blue and probably too bright to be a star.
There is no reason to believe that this video is fake, but it is strange that the person making it thought so little fo the incredible UFO outside the plane that he simply panned away from it. For this reason, graded C.
Hopefully this is not a warning of more intense volcanic activity. However, objects are routinely seen around volcanoes such as Popocatapetl in Mexico, and there is generally no subsequent increase in activity.
For years, UFOs were frequent visitors to the Mexico City International Airport, and now Latin American UFO Investigator Scott Corralles reports that they came back in 2010, most recently in the form of a glowing blue object that hovered over the airport and was observed, as were the others, by many aviation professionals.
If these are ordinary object, why don't they just say so? Two reasons: first, the are not allowed to propaganize the American public and therefore cannot lie; second, they are not allowed to admit the objects are unknown until the military says they aren't dangerous, which they will not do. Thus the silence.
An interesting photo. Of course, it could as easily be made of rubber or ceramic, but the whole presentation has a feel of authenticity--as a good hoax would, too, of course. For this reason, we cannot grade this A, but we can give it a grade of B until and if evidence of a hoax emerges.
Werner Herzog was allowed to film 6 days in Chauvet Cave, which was discovered in southern France in 1994. Many of the creatures depicted in the cave could only be found thousands of miles south, in central Africa, when the paintings in the cave were created 24,000 to 32,000 years ago, and some of them are of creatures entirely unknown. The public is not allowed in the cave due to the fragility of the art, and the film's release next April is one of the first extensive showings of its contents.
They come in like this every day from all over the world. Once, this story would have stunned the entire planet. Now, it's completely ordinary. Why? Because we have no idea what they are, and we've lost interest in the secret! Well done, visitors, you've got what you want: total openness and complete secrecy.
