Description or the object; (2) Grapetrui t (3) Orange light (5) Not applicable b. Description or course ot object: (1) The object just appeared and was sighted by the observer who vas travelling in an automobile at the time of' the sighting. (2) 10 degrees from the horizon (3) JO degrees from the horizon. At first the object appeared to be stationery, then it started to move in a wester~ heading and grew smaller then J arger in size. 'lbe object just vanished. (6) Tbe obJect was visible ror approximately rive minutes. (1) Grollrd ...c (3) Not applicable d. Time and date or sighting: e. Location or Observer: Penna Park, Pennsylvania approx1trately 20 miles Northwest or Philadelphia, Pa. t. Identifying Information on Observer: (1) Not applicable (2) Captain, tBN, United States Naval Air Development Center, Johnsville, Pa., of the Aviation Acceleration Development Laboratory. Estimated to be completely reliable. g. Weather and Winds Aloft Conditions at Time and Place ot Sighting: (1) Overhead clear 50~ cloud cover 3000 to 7000 feet cei~ings to the South or observer toward the object. (2) Winds aloft: Surf :tee: 090/12 (3) Ceiling: 1500 (4) Viaibilit7: 10 miles (5) Cloud cover: j. Unknown k. Williams. Barnett, Captain, USAF, Chief, Intelligence Division, New York Air Defense Sector, Mcquire Air Force Base, New Jersey Preliminary ana~sis of the possible cause or the sighting indicated two possibilities: A check or tbe air traffic fl1ing in the Philadelphia, Pennsylvania area indicates that the observer 1oay have seen jet exhaust or an aircraft climbing out after takeoff and going away from the observer. The ceilings were approximate~ 1500 feet in tbe Philadelphia area and an7 Jet (connercial or otherwise) entering the cloud cover would neceasari]J disappear. The other possibility was brought out in ~ conversation with the observer. He noted some advertising searchl1 ghta sbin1 ng in the Philadelpbi a area approximately at the time or the sighting but did not think that this caused the UFO. However, if the cloud cover over the searchlight area was lower that over tbe observer, it is felt that the circling light ooul d have caused a rei'leotion on tbe clouds. Since tbe cloud cover was broken the ligbt reflection could have given tbe observer the orange light aDd size and shape or the object. No further information is available at this time.
