South Table Mountain (Colorado) — 1950

Mr. Quintana of Denver saw a silvery-green ovoid object hovering about 15 m above a slope and landing slowly in a small ravine. Then it shot upward at very high speed. Its diameter was about 20 m, and it had a revolving middle band. A greenish light flashed under it, and the witness felt a rush of air and a pungent smell. (FS July, 59)
