Flying Saucers or Unconventional Aircraft

This memorandum, addressed to the Director of Central Intelligence, concerns a report of a sighting of two flying saucers or disc-like unconventional aircraft near Prague, dated 13 October 1955. The document details an interview with one of the four observers of the event. The witness reported that the objects initially rose vertically before approaching a train and passing overhead at a high altitude of approximately 5,000 feet. However, the witness failed to observe the actual body of the objects and could not confirm their shape, noting they could have been round, disc-like, or square. The author of the memorandum expresses skepticism regarding the report, suggesting that the witness's observations were likely influenced by prior knowledge of flying saucers and that the witness was not in a position to properly observe the objects. The author concludes that the testimony alone is insufficient to confirm the existence of any unconventional aircraft and recommends that the other observers be interrogated. The document also references a previous investigation led by Dr. Robertson, which concluded that flying saucer sightings posed no threat to the security of the United States.
