David Talbott continues his presentation on Martian mysteries, from the forthcoming DVD, "The Cosmic Thunderbolt" (Episode Two in the series SYMBOLS OF AN ALIEN SKY).
Additional glimpses from Episode 2:
"The Cosmic Thunderbolt," Part 1
"The Cosmic Thunderbolts," Part 2
"Planet of a Thousand Mysteries"
Since this video is part of a much larger presentation of evidence, and all of the evidence is interlinked, it is best to start at the beginning.
