Mechanics in Ancient Aircraft In Ancient Aeronautics

Research of ancient air craft PUSHPAKA VIMANA is my dream. The views about ancient aircraft struck my mind when I read about SETHU SAMUTHIRA project of India. SETHU SAMUTHIRA project is posing a great challenge to India, not only India but to the whole world. Though there are advanced technologies in India we still do not understand the complicated techniques used by our ancestors .so I decided to understand the technology used in the vimana .which was developed before B.C, by reading many Sanskrit books of RAMAYANAM.I got a proof that they used mercury as fuel for the aircraft, and the surprising fact that was revealed was they used gravity neutralization method, but the steps of constructing aircraft were not in the text books. After some calculations I assumed this theory. As years have gone by our country lost many text and details related to the techniques they used in those periods
