Referenced in ancient Sanskrit texts like the Mahābhārata and Vaimanika Shastra, Vimanas are described as flying chariots powered by “liquid air” and mercury engines, capable of crossing worlds. Scholars see them as poetic metaphors—yet some researchers claim the blueprints resemble lost aeronautical technology. The Tirumalai Hills are often cited as one of several sites where these crafts may have descended, with carvings and temple inscriptions depicting winged vehicles and sky battles. Whether divine allegory or evidence of forgotten science, the legend of India’s ancient aircraft continues to defy easy explanation.
