Engineer, Sirenio Garcia Chavez took 2 photographs on April 12th, 1975, at about 13:30, after lunch, of UFOs over the ex-Hasienda de San Juan Ixtilmanco, in Hidalgo state of Mexico. The presence of the two flying discs above the delapitated shell of the old hacienda is indisputable. The objects were not seen at the time by Garcia Chavez, nor by either of the two neighbors seen in the complete picture. Upon analysis, the objects in the two photographs were calculated to be some 8 meters in diameter and some 40 to 20 meters respectively from the camera.
