It isn't real, and shouldn't be considered so. I present my analysis:
1. Concerning the first section of the video, "The attack;" Clearly, the camera was shooting nothing but sky, before this huge thing conveniently
floats into view. It performs every maneuver you expect
it to perform, so that it looks convincing to the casual observer. It moves across the
sun, so you can observe how it interacts with the light. Then it unleashes some sort of energy weapon, and everything is wiped out. There is no reason
why the footage would have survived such an attack: you only see such parallels in movies.
2. The second section, shot from the car: was it truly implied that visible distortions were due to the craft's proximity to the car? Because if that
is the case, there should have been such distortions in the first video, where the craft appeared even closer.
3. The third section, "1968:" It is (to me) fairly obvious that this is merely 'footage' that has been run through a filter. And again
craft does the same thing; flies across the sun, so that it blots out the light. Some will recall that the Haiti footage shared this characteristic;
one which initially made it somewhat difficult to 'disprove.' Until, of course, the Vue 6 revelation.
Conclusion: don't be distracted by the craft. Instead, watch what the craft does. Also, there has to be a reason why the camera caught the craft: I
don't know how many people enjoy filming the sky, these days.
Now, if you'll excuse me, I must preserve the winter sky for posterity: in high-resolution digital video format.
