September 22, 1954 — nr. Marshfield, MO
11:00 a.m. Private pilot Jack N. Williams and Ernest J. Ash see a thin, translucent, tan, asymmetrical boomerang-shaped object about 6–7 ft wide, revolving as it hovers to the southwest at about 600 ft altitude and 600 ft distance. The object ascends to 1,500 ft in 20 seconds, descends, then tumbles down behind some trees after emitting a white puff of smoke or vapor. Marks are found in the ground, “pulverized.” The sighting lasts 15 minutes.
