The Vaimanika Shastra is an early 20th century Sanskrit text about the science involved with the study, design, and manufacturing of airflight capable machines, or the techniques of operating aircraft and rocketry within the atmosphere.It claimed to be obtained by mental channeling, about construction of vimānas, the “chariots of the Gods.” The existence of the text was revealed in 1952 by G. R. Josyer, according to whom it is due to one Pandit Subbaraya Shastry, who dictated it in 1918-1923. A Hindi translation was published in 1959, the Sanskrit text with an English translation in 1973.
