MP: The last two posts between you and MJT have made very interesting reading and imo very constructive. One thing that surprises me is your agreement that the granit plugs were built in. Firstly do most Egyptologists agree with you both on this? Secondly, if the plugs were fully surrounded by masonary at an early stage of the building process surely this would suggest that the ascending passage above the plugs was never used? If that were the case then nothing was ever transported upwards from the GP entrance, (unless perhaps from the base of the well shaft). Is that how you see it?
SC: Egyptologists do not agree with this view at all since it would, as you pointed out, render it impossible for anything to be moved up the Ascending Passage and it is this very passage that the Egyptologists insist Khufu's mummified body passed through (via the Grand Gallery and Ante Chamber) to his supposed final resting place within the King's Chamber. One can hardly imagine that Khufu's mummified remains would be dragged up the extremely narrow Well-Shaft.
This not inconsiderable problem for the tomb theory in no way presents a barrier to the RVT since the RVT proposes that the recovery contents be be lowered into the chambers from the open roof of the KC or the Ante Chamber. The chamber would finally be sealed and the pyramid construction then continues until completion. The RVT does not require to wait until the king has died for the chambers to be sealed and the pyramid completed.
There's an interesting article here about the granite plugs and how it seems unlikely that they could have served as a security measure. Again this goes against the conventional tomb theory but lends further support to the RVT.
