Vaimanika Shastra: Sanskrit Epics, Ancient Astronaut Theories, Maharishi, Indian Institute of Science, Bangalore, Vimana, Shivkar Bapuji Talpade, Chariots of the Gods

The Vaimanika Shastra is an early 20th century Sanskrit text on aeronautics, claimed to be obtained by mental channelling, about construction of vimanas, the "chariots of the Gods", self-moving aerial cars mentioned in the Sanskrit epics. 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. It has 3000 shlokas in eight chapters and was attributed by Shastry to Maharishi Bharadvaja, which makes it of purportedly "ancient" origin, and hence it has a certain notability in ancient astronaut theories.
