Temple of Seti I Helicopter hieroglyphs

The Temple of Seti I was constructed in memory of the 19th Dynasty and it was completed by his son, Ramessess II. Part of the plaster in the overhang has crumbled, revealing some interesting and unique hieroglyphics. They depicted strangely similar modern machines that caused eyebrows to raise wondering if Egyptians knew about modern technology.
Background
Pharaoh Seti I
Seti I was the son of Ramses I and Queen Sitre. He followed the footsteps of his father, which was to become a military man. While in the military, he earned multiple titles, like troop commander, vizier and head archer, and this made him to be considered a powerful man throughout Egypt. He reigned from 1291 to 1279 BCE. Since his father only reigned Egypt for 2 years, people claimed that Seti was the real founder of the greatness of the Ramessids. During his reign, he led his army northward to restore Egyptian prestige. He battled in northern Palestine and Syria, but ended it with a peace treaty that may have established the frontier at Kadesh on the Orontes River. Seti truly made Egypt prosper during his reign. He fortified the frontier, dug wells, open mines, rebuilt temples and shrines that have been falling apart, and continued the work of his father in completing the great hypostyle hall at Karnak, which is deemed to be the most magnificent monument in Egyptian architecture.
