Direction of Motion: Moving upward Satellites: (AFCIN-493, PHONE 69219) Negative Astronomical Phenomena (Meteor, Comet, Planet, etc): Ruled out Radar Analysis (AFCIN-4E1): - Natural Phenomena (Ball Lightning, etc): Ruled out Aircraft, Balloons, Airships, etc: Ruled out Other: Briefly sighted Evaluation of Source Reliability: - Analysis and Conclusions: The object sighted is apparently not a star, planet, meteor, comet, or any other astronomical phenomena known. It is believed to be an unidentified flying object. (Description omitted) The text in the document reads: The sighting of not more than one minute's duration appeared to be a flat, brilliantly lighted, metallic object of large size which moved at a very high speed over the sea leaving no trace. The object disappeared in the direction of Utlangan before the observer had time to take a clear look and estimate its size more definitely. The brilliant light radiated was observed for perhaps 5 to 10 seconds. CONCLUSION: The observer was unable to form a definite opinion as to the nature of the object observed, but stated that the sighting was so brief that he could not be certain as to its exact size, shape, or distance.
