Moon Dust
Moon Dust was a tag-line used to notify the USAF that an object from space had crashed and was available to retrieve and potentially exploit. Moon Dust teams were called in to retrieve these objects all over the world.
Kevin Randle wrote a book about Moon Dust and other UFO stories. He has reported that a new edition will be coming out this year.
