Flying Vimanas, is this inspiration for current NASA technology? Many years ago, some Sanskrit documents from the 4th Century BC, which had been recovered from Lhasa, Tibet, were sent to the University of Chandrigarh where they were translated into English by no less than a certain Dr Ruth Reyna.
Dr Reyna went on to claim that the documents contain instructions on how to build an aircraft with interstellar capabilities. According to Reyna, these aircraft used anti-gravitational propulsion. The document suddenly gained a lot of attention when it was announced that China would be including parts of the information for study as part of their space program.
