In the Vedic literature of India, there are many descriptions of flying machines that are generally called Vimanas.
India's national epic, The Mahabharata, is a poem of vast length and complexity.
There are no physical remains of ancient Indian aircraft technology but references to ancient flying machines are commonplace in the ancient Indian texts. Several popular ancient epics describe their use in warfare.
Depending on one's point of view, either it contains some of the earliest known science fiction, or it records conflict between beings with weapons as powerful and advanced as anything used today.
The VIMANA are spacecraft, land leviathans, airplanes and interdimensional craft described in great technical detail in the ancient Vedic literature of India.
Some were said to be as fast as thought itself.
