1999-03-17 - Chicago, IL - Triangle

I was inside my house and I looked up thru my skylight to see if there was a full moon. I saw a triangle shaped craft moving from south to north-northwest. There was a white spotlight at one corner and a green light at the two other corners. After about 20 minutes I went out my front door to get a better look. It was a cold and windy night but the sky was clear. I stood on the sidewalk and saw the triangular craft again and then I noticed the other two craft and the lights were the same on them. Now they didn't seem to be moving. A man and a woman came by and I asked them if they believed in UFO's. The man said they were in a hurry and they kept walking down the street. Then a couple of minutes later another couple, a man and woman, came by and I asked them what did they think the lights were up in the sky. After a minute the guy said he thought it might be a comet. The woman said she thought she saw blue or green lights. Then they left after a few minutes. The craft still didn't seem to be moving and after about fifteen minutes I saw a small airplane, flying from north to southeast, fly under the large triangular object. In comparison to the plane, the object seemed to be at least five times bigger than the plane. After another 15 minutes observing the objects, the clouds started to move in and I went inside my house and didn't see them anymore.
