Donnybrook (North Dakota) — August 19, 1966 (1650)
A border patrolman saw a bright, shiny disk on its edge, 10 m in diameter, 5 m high, floating down the side of a hill, wobbling from side to side 3 m above ground. It reached the valley floor, climbed to about 30 m, and moved across to a small reservoir where it assumed a horizontal posi- ion. A dome then became visible on top of the disk. It hovered for one min and seemed about to land less han 80 m away, but tilted back on edge and flew into he clouds at high speed. (Atic)
