Mumbai: The second day of the Indian Science Congress hosted at Mumbai University here Sunday saw a lecture examining ancient aviation technology in the Vedas.
The hosting of the lecture, presented by Captain Anand J Bodas, a retired principal of a pilot training facility, had recently attracted criticism from some scientists who said it undermined the empirical evidence on which the Congress was founded.
Drawing upon the ancient Vedic texts to support the view that there was flying technology in ancient India, Bodas said, "There is a reference of ancient aviation in the Rigveda."
He said Maharishi Bharadwaj spoke 7,000 years ago of "the existence of aeroplanes which travel from one country to another, from one continent to another and from one planet to another. He mentioned 97 reference books for aviation."
"History merely notes that the Wright brothers first flew in 1904," he said.
Bharadwaj, who authored the book Vimana Samhita, had written about various types of metal alloys used to build an aeroplane. "Now we have to import aeroplane alloys. The young generation should study the alloys mentioned in his book and make them here," Bodas said.
He also spoke of the "huge" aeroplanes which flew in ancient India. "The basic structure was of 60 by 60 feet and in some cases, over 200 feet. They were jumbo planes," he said.
"The ancient planes had 40 small engines. Today's aviation does not know even of flexible exhaust system," he said.
The ancient Indian radar system was called rooparkanrahasya. "In this system, the shape of the aeroplane was presented to the observer, instead of the mere blimp that is seen on modern radar systems," he said.
Bharadwaj's book mentioned a diet of pilots. It contained of milk of buffalo, cow and sheep for specific periods, Bodas said.
The pilot's dress cloth came from vegetation grown underwater, he said.
Indian Science Congress Association (ISCA) which hosts the annual event, is a premier scientific organisation of India with a membership strength of more than 30,000 scientists. It was founded in 1914 with the objective to "advance and promote the cause of science in India.
