a string! 96 REVELATIONS who used a single camera with a 50mm focal length lens working at f/100 and shooting at one one-hundredth of a second. The camera was held (probably on a tripod) about three and a half feet above the ground and it moved only a few feet from its primary location. The film used was a Valca emulsion made in Spain, with an ASA speed of 400. The original story was clearly a pack of lies. Once the geometric and optical data were known, the Toulouse analysts digitized the photographs and made the following observations: (1) the object had to be only about 8.5 inches in diameter and ten feet away from the camera in order for the sharpness of the details to match those of the landscape; (2) the object had to be translucent, including the part bearing the insignia, in order to account for the calculations of reflected light; (3) in terms of surface lighting characteristics, the dome of the object was compatible with the parameters of a small plastic cup or similar polished material. On one of the photographs, digital enhancement clearly showed that the disk was suspended from In other words, the pictures could have been taken using a small model made of plastic plates, a cup, and a black ink marker for the insignia. They could have been prepared sometime before the date of the actual sighting, in similar conditions of filtered sunlight, at the same hour of the day. Antonio Ribera disputes these findings. In a letter circulated to various colleagues, he asked: "What do you make of the circumstantial evidence represented by the actual witnesses of the craft which was flying low over San Jose de Valderas, and who describe it exactly as it can be seen in the photographs?" Poher and I think that somebody simply built a flying model of a saucer and maneuvered it, possibly by radio control, over the unsuspect- ing witnesses. One look at a map of the southwestern suburbs of Madrid shows that right between Aluche and San Jose de Valderas lie an airport and the Aerotechnical School, both of which would have been conve- nient places to build, control, and hide a disk-shaped model. The photo- graphs could have been taken several days before at the same location. From a technical point of view it was not a perfect case—only almost-
