Castetnau-Camblong 1979, brief triangular observation

Summary

In July 1979, a witness in Castetnau-Camblong observed a triangular object with a rusty orange color. While using an astronomical lens to view the landscape, the witness noticed a stationary object that quickly disappeared behind fog. The observation lasted less than 30 seconds, limiting the details that could be recorded. Although initially thought to be a tetrahedral weather balloon, the witness's description did not fully match that hypothesis. Without an exact date, it was impossible to verify balloon launches or weather conditions, leading to the case being classified as "C," meaning unexplained with the available data.
