Yes, he does talk about Fix's hypothesis in the Atlantis Rising article. In fact, he even states the man's name and his theory with proper accredition...Not sure why you all are thinking that he's "borrowing from somebody else's idea" and not giving proper credit. I believe he credits Fix's hypothesis directly with being from Pyramid Odyssey, 1978, p. 93... From what I understand, this piece by Dr. Schoch is to basically set the tone of what it was like to visit the chambers and some of his reflections while he was in there...including reflecting on other's theories...
