Does the 'Vaimanika Shastra' prove that ancient Indians built working aircraft?
Indian claim not supported by evidenceTechnology & engineering
Indian claim
The Vaimanika Shastra, said to come from the sage Bharadvaja, describes ancient flying machines (vimanas) such as the Rukma, Sundara, Shakuna and Tripura, with their metals, engines and pilot training. A paper at the 2015 Indian Science Congress (Mumbai) repeated that vimanas could fly between planets.
Evidence for the Indian claim
- The Ramayana and other epics and Puranas describe flying chariots such as the Pushpaka Vimana, showing that the idea of flight is very old in Indian imagination.
- The text was presented by G.R. Josyer in 1952 as dictated by Pandit Subbaraya Shastry (1866–1940), who said it was revealed to him.
Commonly credited to
Aeronautical engineers say the text is modern and the machines it describes could not fly; powered heavier-than-air flight dates from 1903.
Evidence for the other claim
- A 1974 study by five IISc Bangalore aeronautical engineers (H.S. Mukunda, S.M. Deshpande, H.R. Nagendra, A. Prabhu, S.P. Govindaraju) concluded that the text is of early 20th-century origin.
- The same study found the craft were 'poor concoctions' that showed no grasp of aeronautics, and judged them impossible to fly.
- No ancient manuscript of the text has been found; it was dictated in 1918–1923.
- Many Indian scientists publicly criticised the 2015 Science Congress paper.
What historians and scientists say
The flying chariots of the epics are a rich literary and religious image, not engineering records. The Vaimanika Shastra is a 20th-century text, and the IISc study found its aircraft could not fly.
