Another thing I can elaborate on is from what I've gathered about their propulsion systems. While they are in material form. First of all, their consoles are interfaced through consciousness. They pretty much connect to their craft by entering a certain state of awareness and control it by thought and feeling. These ET crafts don't push through space. The craft has the ability the somehow warp space/time around the craft and it practically "falls" into the space in which direction it is travelling. This is how they can travel at super mach speeds without being smooshed by inertial forces. So technically They aren't really moving at all. They're just manipulating the space around the craft allowing them to be "placed" in a different position. Bob Lazar who claimed to work at Groomes Lake Facility (Area-51) described the craft that he worked on as being one solid piece. No seems or rivits, nuts, bolts. All one solid continuous piece. He said that the inside instruments look as if they were molded out of wax. All rounded and smooth edges. No sharp corners anywhere. They measured delay from on end of the craft to the next and didn't get any delay at all. It was instant. He said this is where fiber optic technology came from.
