[Ref. 312] GERARD BARTHEL AND JACQUES BRUCKER:
The two authors indicate an observation in Dax on October 11, 1954, appearing in the "Sud-Ouest" newspaper for October 12, 1954:
"A hunter in company of a comrade saw within rifle range a machine in the shape of a grand piano. On the top, two glazed cupolas let green-grayish gleams filter, on the side, port-holes through which filtered yellow rays. At the back were two kinds of exhaust pipes. The machine was motionless within 50 meters of them after a fulgurating descent, then described some circles and set out again vertically."
