[Ref. 50:] CHARLES GARREAU ET RAYMOND LAVIER:
From a newspaper clipping of their personal files, the two ufologists report that a landing occurred on October 27, 1954, in Plemet in the Côtes-du-Nord.
In conclusion for their description of that case, they add that in Treglamus, in the Côte-d'Armor also, at 50 km in the North-West of that landing, "several people saw a similar machine."
[Ref. 223] MICHEL FIGUET AND JEAN-LOUIS RUCHON:
The two authors indicate that in Tréglamus, near Guinchamp, in the department of Côtes-d'Armor, on October 27 1954 at an unspecified time, numerous witnesses observed a brilliant disc.
