Observer after reading reports about disc-shaped aircraft recalled a nearly forgotten incident which occurred some 20 miles NW of Habberbishopshiem, Germany after the last war.

Object first sighted some 8 to 10 miles to observers' front - at approx 5,000 ft high. It rapidly approached, descending slowly. About a mile away it stopped its horizontal motion but continued a slow oscillating descent similar to a descending parachute. Then it suddenly dropped in a spiral motion. Tried to locate the place where it fell but it became too dark. The first impression of the observer was that it was a cloud but it was traveling at right angles to the wind.
