Removed this line: Project Sign was acknowledged as the reinstated C23 descendent of Project Blue Book, an organisation created in the middle C20 to research reports of U.F.O.s. Besides the curious abbreviations for 23rd century and 20th century, and its seemingly random placement within the article, the description previously given of Project Sign suggests the only thing it has in common with Project Blue Book is the word "Project". If this factoid is factual and relevant, I hope it will be better explained. --Seventy 01:44, 1 November 2006 (UTC)

It was stated in Spectre and Dark Victory themselves that Project Sign is the reinstated Project Blue Book. Is that a good enough explanation? [User: Stripey].
