May 1, 1952 — Tucson, AZ
9:10 a.m. Air intelligence officer Maj. Rudolph Pestalozzi and an airman standing outside the Davis-Monthan AFB base hospital, Tucson, Arizona, watch two shiny, round objects overtake a B-36 flying above. The objects slow down to match the plane’s speed and remain in formation with them for 20 seconds.
Then they make a sharp, no-radius turn away from the B-36, moving away a bit. Then one of the objects stops and hovers. Both are silent, and the crew estimates they have a diameter of 20–25 feet and a thickness of 10–12 feet. [Eberhart]
