Soirans (from our part. corresp.). -- Hunting in the forest, Mr. Eugène Bonnaire, from Soirans, near Auxonne (Côte-d'Or) was intrigued by a mysterious object located at the top of an oak tree.
Climbing up the tree to unhook this mysterious craft, after finding by the police... it was a "Modulator 32 944 US" weather balloon.
It wasn't a flying saucer, as one might have thought!
