Project 10073 Record Card — Wegenstetten, Germany, 13 September 1955

This document consists of a Project 10073 record card and an accompanying report regarding a sighting on September 13, 1955, in Wegenstetten, Germany. The primary witness, identified as a doctor and his wife, reported observing a rectangular object traveling at high speed. The object was described as having lights along its side and being four times as long as it was wide. The witness provided a detailed account in German, noting that the object appeared to be made of an aluminium-bronze material on one side and was dark on the other. The observer estimated the object's speed at 150 km/second and its altitude at 1200 km. The report includes a sketch of the object, which depicts a rectangular structure with a grid-like pattern of windows. Despite the detailed description provided by the witness, the official conclusion recorded on the ATIC form is that the sighting was a meteor. The document also references a discussion at an astronautical congress regarding rocket propulsion and ion-based propulsion systems, which the witness seemingly attempted to relate to the observed phenomenon.
