Check out this amazing aerial photograph of the Great Pyramid of Giza, where you can see all eight sides (not just four) in clear view. This unique concave feature, which is not visible from the ground, can only be seen in aerial photos or on certain days when the sun hits the structures at a particular angle. Interestingly, this feature was first discovered by a British Air Force pilot who stumbled upon it accidentally in 1940. However, it had already been noted by the English Egyptologist Sir Flinders Petrie back in the 1870s, who believed that it was an intentional aspect of the pyramid's design rather than a construction error.
