Hopkinsville - S2-E4
Other mistake: Mr. Shoemaker tells Dr. Hynek and the Captain that the aliens he saw had three-fingered hands. A short while later he is caught giving a description of the aliens to a reporter. The picture drawn - based on Mr. Shoemaker's description - shows five-fingered hands. Plus later Dr. Hynek discovers a bio-luminescent hand print on a tree. It shows four fingers. (00:10:55)
Suggested correction: This is proved as a hoax so what the man said about the alien having three fingers could just have him mis-remembering the hoax details.
I can see that. OK.
