Metallic triangular object reported years later in Strasbourg

Summary

A witness recalls seeing in Strasbourg, sometime between 1990 and 1991, a metallic-grey triangular object with three bright lights and geometric designs. According to the account, the object momentarily blocked the sun, drifted slowly and silently, then suddenly vanished at high speed. The testimony was not given until 2008, and the lack of a precise date or additional information prevents any conclusive investigation. No concrete hypotheses could be confirmed.
