Large Black colored triangle shaped ship. Eugene, OR 1984

A large trianglar craft was hovering silently about 30 in the air, along side the road. About 50 feet from the road. The craft was about 40 feet across. It had flat sides that were about 4 feet thick.. and looked to be made of metal, a dark none-metalic looking in color, with a lot of tubes and stuff all over it. There were three bright white lights, one on each corner, with a bright silver metalic colored ring around each light that was spinning. The rings had slits in them. There was a small red light in the middle that floated down to the ground and back up. There was a strong blowing wind or breeze.. but no sound at all. Other people were pulling off the side of the road to watch it. We left as soon as we discovered that it wasn't anything we'd ever seen before. I was only 17 years old, and my boyfriend at the time was 20, it scared as to death. The next day it was on the local radio.
Date in March 1984 is approximate.  PD
