Factual error: Air Force personnel are retrieving supposedly alien debris from a forest. They are wearing dress blues, ties and all. This would never happen. They should be wearing what were then called "fatigues", essentially a precursor of the BDUs in use today. (00:16:00)
Other mistake: The West Virginia News publishes a headline about the Flatwood Monster dated October 18, 1952. The incident took place on September 12, which was 36 days before. It does not make sense that a newspaper would print a headline story 36 days after it happened. (00:25:20)
