Rectangular object with possible windows over Agen

Summary

On 24 March 1978, a witness in Agen (Lot-et-Garonne) saw an intense red light apparently surrounding a rectangular object. Inside it, two yellow circles — possibly windows — were visible. The object moved horizontally before vanishing abruptly, leaving a faint pinkish trail. The description is clear but brief, with no additional data or witnesses. GEIPAN classified the case C — a one-off observation with no confirmation or follow-up.
