I just want to mention that in the book I refer to The Hall of Maat and Graham Hancock message boards. I also refer to the work of Robert Bauval(OCT) and the late Clive Ross. I include a post by Jon Bodsworth regarding the originally planned size of Khafre's pyramid, and Snell's law being applied to the Giza design(Don Barone and Jonny McAneney posts).
