I was at work and taking a smoke break in the middle of the afternoon. Clear skies and daylight. On the horizon, not far away, i saw an object clearing the trees and comming toward me. It was shaped like a disc, but with a "handle" protruding from it. Like a frying pan. It was brown in color and moving VERY slowly. I immeadiately knew that I had no idea what this was. The only guess I had was a soaring bird. However, that thought certainly didn't last. Perhaps4-6 mph. It's course lead it DIRECTLY over my head. 100' up. It was COMPLETELY silent and totaly straight. I can't emphisize this part enough. It didn't go up, down, left, right...nothing. TOTALY straight. It was not a large object. About the size of a car hood. I used me cell phone to call a coworker inside. He came outside and witnessed this as well. The object was brown and featureless. It disappeared over the other horizon and was in my view for 3-4 minutes and for a distance of 600 yards or so.
