D3-UFOB-3-55 — 1955-05-15 — New York City, New York

On 15 May 1955 at 2000Z, Warren Stagmond, a 31-year-old television technician, was on the roof of his New York City apartment when he saw a large opaque object at 45 degrees elevation that hovered, moved rapidly north on a bouncing trajectory, returned to its original position with the same motion, and repeated the cycle before disappearing north. Sighting lasted about 1.5 minutes; the object gleamed as though metallic with no sound or visible exhaust trail.
