Intense light near a railway in Le Luc explained as a helicopter in 1984

Summary

In October 1984, two drivers in Le Luc spotted an intense light near a railway line — a white ball emitting a sharply defined beam. With their car windows closed, they heard no noise. The investigation determined it was the six-hundred-watt searchlight of a Puma helicopter approaching a nearby military base for landing. The case was resolved: what seemed unexplainable had a clearly identified origin.
