George Knapp conducted an in-depth interview with Luis Elizondo. Elizondo spent ten years as head of a secret study of Unidentified Aerial Objects, he was also instrumental in the release of official UFO videos recorded by military pilots.
AATIP (Advanced Aerial Threat Identification Program), was a Department Of Defense Program out of the Pentagon tasked with studying the UFO phenomenon. In this interview, one of the things we learn is that the program still continues to this day.
The Pentagon study focused, in part, on Skinwalker Ranch.
