## CONFIDENTE STRICTED ## ```markdown ``` Observer first noticed a white smoke trail and while searching for its source he saw an object 4 to 6 ft in length x 10 to 14 inches wide and of a metal color which gave off a very bright reflection like highly polished chromium. It was first observed at 1030 position to the automobile. Upon reaching a 1200 position it was engulfed in a puff of dark gray smoke about 10 ft in diameter. There was no change in the color of the smoke. The object was traveling at terrific speed and seemed to be in a very shallow dive. When the puff of smoke appeared the object disappeared completely; no particles were observed falling from it. The point of disappearance seemed to be about 800 yards in front of Switzer. There was no possibility of being hidden by vegetation or terrain. It appeared rectangular for the most part but once it appeared to have a very slightly curved top surface. It seemed more rocket-like than disc-like, and seemed tilted in a semi-circle. Agent notes that the point of observation would afford a sweeping view thru 40° of the canyon and the south side of Webber Creek. (Switzer was not definite as to what part of the field of view he had seen the object and indicated that it could have been as far as the horizon.) Any object or particles thereof would be in a six square mile area of wooded mountainous terrain full of canyons and ravines. Agent thought that witness could have seen a conventional type aircraft which due to the distance from which it was observed presented no distinguishing features for the short period it was under observation. However, agent could not account for the smoke trail. CONFIDENTIAL RESTRICTED
