Amazingly, no blueprint for a mammoth slide going down the side. Paleofuture reveals:
In a series of illustrations under the bold headline, “Mammoth Flying Swing to Give Bird’s Eye Pyramid View,” we see the pyramids as they could have been — the main attractions in Giza’s own version of Disneyland.
Signed by Art Williamson in the June 1931 issue of Modern Mechanics and Invention magazine, the illustrations show three cars swirling around the top of a pyramid, driven by a huge electric motor. The thrill seekers then were supposed to board the ride by crossing a gangplank that gives me vertigo just looking at it.
So why didn’t this unbelievably irreverent idea come to pass? One suspects it might have had something to do with objections from the Egyptian government. The illustration mentions that when (not if) the government’s consent is obtained, this amazing project will become a reality.
