Context
Autumn 1954. France was in the middle of a flying saucer wave. On the night of Tuesday 28 September, two SNCF railwaymen from the Nantes depot were running a locomotive haut-le-pied, an engine with no train behind it, from Nantes towards Auray. Émile Gérard, 49, came from Savenay. Victor Paroux, 40, lived on Boulevard des Poilus in Nantes.
