I saw a dark v cloud fly over my head at 2000 mphI was out back of my aunts house smoking it was chilly and a little breezy. Then all of a sudden I hear a whoosh of air heading my way with some speed it reminded me of the mlrs rockets I have witnessed before but with no engine sound. I look up to try and locate the air rushes source and I see a large boomerang shaped cloud moving very low and very very very fast but the only sound that was heard was the wind rushing over it looked like a flock of geese flying in a v shape over head moving at 2000+ mph I kid you not. It was so incredible I never knew such a thing existed however I know now that this is real. I could not believe when I typed into google search UFO sightings in Dallas that the first description I read matched my sighting to the t, that really reinforced exactly what I just saw 20 min ago. I believe we have a new technology out there gentleman. One that is not "out of this world". I don't believe in "ufos" thats why. I'm a ! vet. Infantryman.
