White round object over Thumeries

Summary

In April 1982 four people in Thumeries observed a white, bright, round object. One witness described it as a shiny ball that left a red line as it moved away. A helicopter was considered but the lack of noise raised doubts.

The official investigation was limited: only two testimonies reached investigators, and they lacked essential data such as viewing angles, exact duration or additional confirmation. Imprecise details about the direction of movement and the object's description hindered any conclusive analysis. Nothing contradicts the helicopter hypothesis, but there is not enough solid data to confirm it either. The case was classified C.
