The Silver Dome over Huningue

At around seven in the evening on 26 May 1980 two people out walking at Huningue, in the Haut-Rhin, noticed something odd in a clear sky. One of them was an "officier mécanicien naviguant", a flight engineer officer who flies as aircrew. He described an object that looked metallic. It sat on a round base and rose into a silver dome. It hung stationary 200 or 300 metres above the ground and seemed to rock on its axis. Its lower half was darker and now and then gave off a reddish glow. For six minutes they heard no sound and saw no vapour trail. Then it went up into the clouds in a series of steps and was gone.

What is on the record

GEIPAN is the unit of the French space agency CNES that investigates unidentified aerial phenomena. It holds this case as HUNINGUE (68) 26.05.1980 and classes it D. Class D means GEIPAN investigated and could not explain it.

The investigation reached the airport. At Bâle/Mulhouse airport, a few kilometres away, a radar echo was recorded. GEIPAN calls it "noyé dans le trafic de la navigation privée et générale et donc peu exploitable" (drowned in private and general aviation traffic, and so of little use). The echo cannot be tied to the object. Inquiries found no other witness and no other information on the French side or in the neighbouring German border area. GEIPAN's conclusion is short: "Ce phénomène reste inexpliqué" (this phenomenon remains unexplained). Its page names no specific hypothesis that was tried and rejected, and it lists no documents.

The flight engineer's trade is what gives the account its weight, since he flew for a living. It is still one description. GEIPAN lists a single testimony, and his companion's view is not given separately.

Why it sits where it does

L0 · SINGLE ACCOUNT. GEIPAN withholds the identities of its witnesses. The record gives the engineer's job but not his name, and he saw the object while out walking, not in the course of his work. So it carries no identified witness. The tier measures sourcing, not the quality of the investigation or of the witnesses. What hovered over Huningue is not resolved here.
