position at the edge of the level, about 45 m away from the traces that will be observed after the departure of the object. Then he discovers a sort of ovoid vehicle, with the general shape of two half-spheres of unequal volume, clearly separated by a flat ledge, extending at least 15 cm and forming a ring around the metallic mass which has a lead-aluminum appearance. The top part extends above the retaining wall, hence the machine has a height between 2 and 2.5 m. The witness does not see any antenna, any porthole, any opening. He notices no extension, no external mechanical peculiarity. The whole thing seems smooth and compact to him. He estimates the horizontal diameter of this machine to be larger than its height. He has no time to continue his observation. The machine lifts off making a slight amount of dust and with a soft whistling. Then it seems to tilt, exposing its underside and it takes off at lightning speed, passing exactly between the two tall trees, at the exact spot from which it had seemed to "fall."

The witness has noticed that the landing trajectory is not identical to the take-off trajectory. When the machine rises and tilts on its departing path the witness notices
