Among all countries in the world, India has inherited
the largest number of ancient manuscripts from time
immemorial. They were written on the widest range of
subjects known to humans.
India had many ancient Sanskrit texts on aeronautics.
The Yantra Sarvaswa of Maharshi Bharadwaja, Vimaana
Chandrika of Maharshi Narayan, Vyoma Yaana Tantra of
Sounaka, and Vyoma Yaanarka of Dandi Natha are some of
them. They contained topics like Maargadhi Karana
(Navigation and control of speed during flight),
Lohaadhi Karana (alloys used for various components of
the aircraft) and Saktyaadhi Karana (production and
usage of various fuels used in aircrafts). Para Sabda
Grahakata is a subject of monitoring the flight tracks
of aircrafts, navigatory communication system, and
monitoring the conversation of the pilots in the
aircrafts. Maharshi Gouthama mentioned 32 models of
aircrafts used in Treta Yuga; only one model among
them, called Pushpaka Vimaanam, became popular in the
Ramayana. The Vaimaanika Sastra describes Tripura
Vimaanam that uses solar powered engine to travel at
three levels - on the land, under the surface of water,
and in the air. Sakuna Vimaanam is a cross between an
aircraft and a rocket - a space shuttle. The British
have robbed most of our Sanskrit manuscripts during
their rule in India. In 1895, Sivasankar Thalpad of
Bombay had constructed an aircraft with an engine which
flew to an altitude of 1500 feet. He was a Vedic
scholar and used to teach at the J.J. School of Arts.
He obtained the technology from some rare Sanskrit
manuscripts. He also wrote a book in Marathi named
Praacheena Vimaana Vidye Chaasodha. Lalaji Rayanji,
Maharaja of Baroda, was one of the many witnesses who
had seen the flying of that aircraft.
Dr.Roberto Pinotti, an Italian scientist, presented a
paper on 'Aeronautics in ancient India' at the World
Space Conference conducted at Bangalore. He told the
conference delegates that those aircrafts were similar
to modern jet-propelled aeroplanes. He agreed that they
represent the most complex and sophisticated designs.
Some of them used radars and imaging technology
Off late, Indians are trying to utilise the technologies
given in the ancient Indian manuscripts.
The Birla Science Center at Hyderabad has produced some
alloys after studying some Hindu manuscripts like
"Vimaana Sastra" and "Amsu Bodhini". The alloys possess
some extra-ordinary properties which are unknown to the
