Alien Base: The Evidence for Extraterrestrial Colonization of Earth: INVESTIGATIONS
Donald Smythe made out a report of the incident which initially was sent to Victor Killick, a retired professor of astronomy, who forwarded it to officials at Mather Air Force Base. On 25 September 1964, Smythe was interviewed at his home by a Captain McCloud and Sergeant R. Barnes of McClellan Air Force Base. Smythe offered his full co-operation and handed over one of his arrowheads for analysis. Nothing unusual was found. He also provided the Air Force investigators with a map of the area. Before leaving, the investigators suggested the following possible explanations for the incident: (a) a group of Japanese; (b) a group of teenagers playing a prank; or (c) a group of Air Force trainees. Suggestions of drinking and hallucination were also voiced by McCloud.
Two or three weekends later, Smythe returned to the scene of the incident, together with his brother, a friend, and one of the hunters. Apart from a few of his cigarette butts, none of the materials he had left there could be seen.
Civilian investigators were impressed by Smythe. ‘Having just reviewed the case files on this fascinating and unusual encounter,’ wrote Paul Cerny in 1995, ‘there is absolutely no doubt in my mind that this incident is factual and authentic. I have spent considerable time and many visits with the main witness, and along with the testimony of the other witnesses, I can rule out any possibility of a hoax.
