India had many ancient texts on Aeronautics. 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, navigation and communication system, and monitoring the conversation of the pilots in the aircraft. Maharishi Gouthama mentioned 32 models of aircrafts used in Treta yuga; only one model among them, called Pushpaka Vimana, became popular in the Ramayana. The Vaimaanika Sastra describes Tripura Vimna that uses Solar powered engine to travel at three levels - on the land, under the surface of water, and in the air. Sakuna Vimaana is a kind of mix of an aircraft and a rocket - a space shuttle. The British have stolen most of our ancient manuscripts during their rule in India. In 1895, Sivasankar Thalpad of Bombay had constructed an aircraft, which flew to an altitude of 1500 feet. He was a Vedic scholar and used to teach at J.J. School of Arts. He obtained the technology from some rare ancient manuscripts. he also wrote a book in Marathi named Praacheena Vimaana Vidye Chaasodha. Lalaji, Maharaja of Baroda, was one of the many wtnesses, who had seen the flying of that aircraft. After untimely death of Prof. Thalpad, his legal heirs sold all his scripts and materials to the British.
