Supersonic or not, I personally witnessed two bizarre craft myself not too long ago. Like in the Socorro case, they were not rotating. UNLIKE the Socorro case, they weren't exactly saucer-shaped. They were kind of rounded/circular on the bottom, but more "bulbous" shaped at the top. NOT something you would typically think of as being all that aerodynamic. I personally did not see them at close enough range to accurately describe their shape. My brother and his friend, however, did, so they described best as they could to me, and from what I saw myself, I can say they were indeed bizarre looking. Silent too. Extremely. They floated along. Actually, drifted is a better word to describe it. In fact, one of them looked like it was kind of swaying a little, as if it were lighter than air (possibly?). My brother and I both thought they acted as if they were kites. They were traversing the sky rather slowly, as well. By that, I mean, UNLESS they were lighter-than-air (or suspended by some type of field), a regular airplane would probably have fallen straight to earth. And remember, these things didn't have wings, and were making no discernible sound, though both other witnesses recalled two things that somewhat resembled arms or appendages at the side. Watched it through the binoculars. I would say they had gotten at least two miles or so to the south, and by that time, it was hard to see them with the naked eye. Then, what really freaked me out: one of them began moving very erratically at a very high rate of speed. This was my expression while watching the display!---> Please Register or Log in to view the hidden image! Imagine a common housefly. Think of its flight pattern. Erratic. Not straight like a hornet's, but almost drunken. That's how this thing was moving around! It would zip from side to side, back and forth, up and down, with little consistency to its flight path. It was just buzzing around madly, to put it simply. I believe, from what I saw through the binoculars (and TRIED to see with my naked eyes) that it was routinely traversing probably 45 degrees from east to west. This was looking south at what must have been a distance of at least two or three miles. I'm not so sure how big the objects were in the first place, so it is not an extremely accurate guess! However, it did that in a matter of seconds, like TWO seconds. Sometimes, when looking through the binoculars, all I saw was a black streak or blur zipping across my field of view. Both my brother and myself watched it. We had to share one pair of binoculars, and I wished we had had a more powerful set! Okay, I've been to airshows. We have an air base nearby, and I am familiar with the speed at which the jets routinely travel, because I've seen it hundreds of times. This zippy little object could not, in my semi-unprofessional opinion, have been going less than 400 miles per hour. And judging by how quickly it was going back and forth, I would say that it could very easily have been going as fast or faster than those jets normally travel. And mind you, it did not at all appear to lose speed when it changed trajectory. It want forward and in reverse, up and down, with effortless ease. And mind you, I'm not an expert in this field either, but I'm guessing the g-forces from that kind of flight would have caused very serious consequences for any normal pilot under normal conditions. And mind you, it STILL wasn't making any noise. My brother was the only one who saw it leave the area. He said it went from due south in a westerly direction, and disappeared on the horizon within a few short seconds. He couldn't stop saying how fast the thing had taken off. We were both like Please Register or Log in to view the hidden image! !!! It was obviously not normal jet propulsion. And what the hell, may I ask anyone, was it DOING flying like that? What was it trying to accomplish, other than showing off? In my semi-professional opinion, I will say it was either a very strange and secretive drone aircraft of the military, or it was not human in origin. I've done a small amount of reading on drone aircraft, and I've seen several models. Most of them are jet-powered. The only thing I can think of that could have powered these things would be some type of ultra-silent, high-powered fan. And the craft would probably have been lighter-than-air, to keep it aloft. Also, all of the drones I've ever seen are pretty aerodynamically shaped, unlike these things. As far as size goes, unfortunately, I did not see them close enough, but between the other two witnesses, it seems they were somewhere between a car and a van as far as size. I thought they were larger, but again, I didn't see them too closely. So the size may be right for a drone. What kind of drone? Something highly unusual.
