Though not seen unless you have night vision binoculars/scope, they avoid detection and come down closer to ground level appearing as a meteor or float down invisible to bare eyes then go bright or blink, suddenly appearing in the sky.
Must be some sort of travel container or traveling porthole perhaps. Sometimes they change shape from this sphere. The end shaped crafts after they somehow transform or shape-shift is typically triangle, square, diamond, rectangle, oblong, oval or a combination – sometimes looking like upside-down pyramid – sometimes have a tail-section trying to mimic our airplanes or helicopters (holograms?) with or without lights that are steady, any color of lights, flashing or not, shape changes while flying which accounts for multiple witnesses describing different details on the same craft.
They usually fly really slow and stay small. The combination of this gives false illusion of being bigger, higher, faster flying man-made craft.
Usually silent, they can sometimes produce a false mimic sound. They have yet to show on radar reports obtained from the FAA– even as a “hit”. Perhaps portable radar like that used in Hessdalen, Norway UFO project might detect them as I believe this type to be the same technology
Just like their study, I am trying to obtain a usable spectrum of their light they produce to try to determine their fuel source that produces it.
Their technology is far far beyond ours. I cannot imagine what living being could be inside something that can expand/contract in size to such varying degrees, that that undergoes such high energy bursts and transformations.
It makes us wonder, though, if the creators of the “Transformers” movie is based upon this group of visitors to Earth. What they like in certain areas is uncertain, although mining, communications, and power production areas seem to be attractants as well as highways.
So far, all they do is fly around for 2-3 hours then shrink back down and move mostly west, I assume, to stay in darkness with the Earth’s rotation, since most activity is during the evening hours after dusk. Sometimes a couple hours before dawn they do the same — always shrinking back down into spheres/orbs and shooting back up into the sky the same way they came down.
