UFOs Past Past Present and Future - A Review

I was looking into a story about a UFO landing at home and Air Force base. And ran into one of my favorite seventies documentaries, it has begun,. First released in 1974 as UFOs past present and future. Rod Serling as a main narrator. Burgess Meredith shows up who's a for air Jacques Valet, Jalen Heineck. William Coleman takes the camera crew on a tour through the Pentagon and talks about UFO cases. The Thomas Mantell incident gives a little history. It's a real nice slice of history.
