Sometimes there are UFO sightings that are just by eyesight, may be in remote areas,, may only be one of two witnesses and may remain unidentified ,never having a rational explanation.
But this one was different, a few days ago radar at Denver approach control was picking up something big, that they couldnt identify. It was 70 miles long and they knew they had no giant flight of airplanes. It was too big to be a flock of geese which can be the area.
They then asked pilots to be on the lookout for this, and an explanaition did result. Guess what that was?
By the way, nothing to do with this UFO but there was a report of steam coming out of a volcano which formed clouds that were saucer shaped, sort of like lenticulars but close to the ground. The photo looked so much like a flying saucer that one would think first of a movie.
