300-400 foot boomerang-shaped object moving at 200 mph?, one-half mile distant at about 2,000 ft altitude. Clear skies, daytime.This sighting occurred in June 1983 in Borger, Texas. I had not reported this earlier because at the time it occurred I had no corroborating witnesses, no photographs, essentially nothing to substantiate the claim. I doubted that anyone would have believed what I saw at the time. However, this sighting stays in the back of my mind, so I am reporting it, if for no other reason, than to have closure.The sighting occurred about 17:30 (Local Time, Central Time Zone) in June 1983. I was in my residence and heard what I thought was a really, really, loud jet. It was so loud that I stepped out on my front porch to see what it was. I looked up and the object was probably one-half mile away at an altitude of probably two thousand feet. (These are only estimations.) It was huge.I had a pair of 10 X 35 binoculars in the living room, so I quickly stepped back inside and grabbed the binoculars. By that time the object was receding, so I might have been better off not using the binoculars. I remember the object filled the binocular’s field of view, which at the time made me wonder just how big this thing actually was.What I saw was a large black boomerang-shaped object, moving from east to west. It was travelling at a modest speed, maybe 200 miles per hour (again, it’s hard to estimate something in the sky without reference points.) I remember as I looked at the object, there were three specific things that struck me. The first was the size…I can only guess that it was 300-400 feet side-to-side and maybe 75-125 feet front-to-back. The second was the tremendous noise the object made. It was LOUD. And, third, the fact that the object was lopsided; that is to say it was asymmetrical. I wondered how it stayed in the air…it didn’t look aerodynamic.I think another reason I never reported this is the fact that it sounded like a really large jet. Maybe it was…if so, it was like nothing I had seen before and have not seen since. The jet sound made me think it was a conventional aircraft, but the shape and the size made me think it was something beyond classification. I did not notice any exhaust or smoke behind the craft.Since then I have seen video of the A1 bomber and other stealth aircraft. On one occasion I saw an A1 pass directly overhead. Believe me, the thing I saw in 1983 makes the A1 look like a toy.By definition, what I saw was a UFO, because it was not identified, it was flying and it was an object. Whether it was of terrestrial origin or somewhere else, I don’t know I wish I did.((NUFORC Note: Witness indicates that date is approximate. PD))
