Pushpak Viman, ("Flower chariot") is the most renowned of the flying
automobiles in Hindu mythology.
Vishvakarma, the celestial architect, designed the Pushpak
Viman.
The term essentially describes an inanimate transport air/space craft that could navigate the Earthly and Celestial realms.
Sanjna, Vishvakarma's daughter, has married the Sun, but she
is so dazzled by his radiance that she asks her father to dim his radiance so
she may be with him.
Vishvakarma does this by removing part of the sun's rays,
which are then fashioned into the Pushpak Viman and other divine weapons.
For a while, the minor god Kubera had possessed the Pushpak
Viman, which he obtained as a reward for practicing extreme physical austerity
(tapas).
It is eventually snatched from Kubera by the demon-king
Ravana, who uses it to perpetrate many acts of oppression, culminating in the
kidnapping of Rama's wife Sita.
Rama uses the Pushpak Viman to return to Ayodhya after
killing Ravana, and then returns the automobile to Kubera.
