It marvels me how the engineers behind this were able to put up something so amazing in the 1970s considering the technology level and civilization timeline at that time. This propeller system is truely wonderful.

The 1970s were not the Middle Ages. Many of the technologies we are using now were already invented.
I am quite aware of that fact. But I still feel these men deserve our commendation. Engineers today have far more to work with compared to the ones who birthed these things 48 years ago.
