Funny! Once, I think it was in like 1987 I thought I saw what was a UFO... it was a black triangle which was flying super low over South Hill of Spokane, Washington. It had no lights except for a red one underneath and it was fairly quiet.... and it was huge! I found out the next day that several people reported the sighting as well. A couple years later, we all found out about the B-2 Stealth bomber... and, that's exactly what it was. It was flying in the direction toward Fairchild AFB.
