Spiral type UFOs in Mexico. Read my earlier post about spiral UFOs here. (Also on UFOMystic.)
These UFOs, the Norway spiral being the most spectacular, share some similarities. They seem to start out the same way, some develop into full out spirals, others don't make it. This is assuming of course they're of the same type of UFO. We don't know what these are: aliens, military, missiles, industrial, who knows. Interesting, for sure. What they are, well, maybe one day we'll find out.
This one is called a "wormhole" by the person who posted it on YouTube. From December 2009:
From 2010, Jamie Maussan at the UFO Congress, with clips of spirals from other countries. I'm not commenting on Maussan's interpretations, just noting the images.
