January 20, 1952 — Spokane, WA
7:20 p.m. Two master sergeants, both intelligence specialists, are walking down a street at Fairchild AFB near Spokane, Washington, when they notice a large, bluish-white, spherical object approaching from the east. It passes north of their position, traveling horizontally and silently, and disappears in the west. They notice it has a long blue tail. It travels underneath low cloud cover at 4,700 feet at 1,400 mph. [Eberhart]
