It was parked (floating) there, how long, I dont know...I went out the backdoor and sat at the stairsteps. I estimate about 1/2 an hour later when I tilted my head back to take a drink of my beverage I noticed this object parked (floating) about 200-300 yards out and about 3 stories high. I placed my drink down and looked at it and wondered, what is that? As soon as I looked at it I would estimate about 20 seconds it then began to move forward very slowly. The aircraft did not fly over me, it went on a 45 degree angle and passed over about 50 yards from my left. While it was approaching my position where I was sitting at I noticed there was no sound, no panels with nuts or bolts, no windows at all and most of all the leaves on the trees did not move and the dirt did not kick up. I also noticed it had a white light underneath it located on the left side of the aircraft and it was moving back and forth in a slow motion like a scanner or copy machine would do. Im very familiar with aircrafts since I worked around them and I assumed it was an AF stealth stationed at Holloman AFB. Our Stealths are "NOT" built with the larger side on front and the smaller end at the back. This aircrat (object) is triangular and the size of a stealth bomber and it had a very sleek and shiny black color close to charcoal. When it flew over I heard a whoooo sound such as the wind hitting a telephone line. I estimate its speed must have been about 25-35 mph. I know it was not a military plane, this one floated with no sound and no pulsion. I dont know why I did not get up and look to see where it went, I know I sat there in dismay and maybe a little shocked at what I saw. Once in awhile at night time I see streaks through the sky, I can tell what is a commercial airline, and I have seen falling stars but this is unique, it disappears into the night. To this day I carry my camera.((NUFORC Note: Date is approximate. Witness elects to remain totally anonymous. PD))
