Mr. Heard’s theories are based in historical records of mysterious emanations since 1877, suggesting they are peaceful observation spaceships piloted by intelligent Greys from our sister planet, Mars. The reason for their coming is concern over the cataclysms on Earth, wars, atomic bomb explosions, etc., which create spots on the Sun. While the factual content can be taken with many grains of salt, the presumption of the moral issues of war and atomic weapons is the evident intention of the book. A must have volume from the Golden Era of Flying Saucers. A splendid collector copy of this classic UFO work.
