I witnessed an object pass over my neighborhood at an unknown altitude but below the cloud cover(1000-2000 ft.). I'm assuming from my own depth perception and the amount of ground illumination striking it that the object was about the size of a small plane and flying at about 1000 ft.above me. I happened to glance up just as I got out of my truck in the driveway and noticed it above the roof of my neighbors house. At first I thought it was a light colored garbage bag carried in the wind-it was blowing pretty hard-when I realized it was moving at a steep angle to the wind and in a steady, straight line.

I saw one object, approximately the same size as a small plane, pass over my neighborhood under the low cloud cover. It was circular in shape and at least flat on the bottom. The only illumination was reflected ground light-I live in a city of 60000-and I would estimate the object to have been about 1000' up. It moved in a steady, straight line to the NNW while the wind was wind was strong from WSW. I was, and remain, stumped. I have kept a close eye on the sky for over 30 years and this is the first time I saw something I can't explain, and I've seen some interesting things. I will try to provide more info on actual weather stats if I can track them down.
