Description

The year was 1952, During the Cold War. Weird sightings were seen all over the United States. As a result, The United States Air Force started a special investigation code-named "Project Blue Book" The President gave special orders to the Air Force for these investigations. One Professor and a Captian went to these unidentified scenes. When they went their witnesses got radiation poisoning or Shock of what they saw.
