The great civilization of India, which is known as Hindu culture, has contributed a lot in the field of science. This shows that they never promoted superstition, nor did the people remain undeveloped and ignorant. Aeronautical science in the twenty-first century is difficult and complex. In manufacturing an aircraft, each and every part of the aircraft has to be carefully tested and evaluated. Material selection, aerofoil selection, weight of the aircraft, thrust required etc. These factors have an impact in the manufacturing of aircraft. Many things were practiced repeatedly in Indian ancient aviation. They have told the material selection making vimana, the instruments used in vimana, the technique of making instruments, the weapons of the enemy vimana, the electric power that runs the vimana, the electric wire and the cover of the wire. This is surprising. I think we should try to study the Indian ancient culture once again. Maybe we can learn something from this. We may not be able to understand those techniques but we can definitely get new ideas to make things easier.
