Pushpaka Vimana is the legendary flying machine of Ravana mentioned in the Ramayana. Ravana had carried away Sita in the Pushpaka Vimana. Origin of Pushpaka Vimanam as per Vishnu Purana is associated with Surya, the Sun God. It is believed that Pushpaka Vimana was carved out using matter from Sun.

It is said that Vishwakarma requested Surya to reduce his heat and he reduced 1/8th of his heat. The flying machine was produced using the reduced heat of Sun.
Another legend has that to reduce the heat of Surya, Vishwakarma removed a part of the burning matter from Surya – it said that Surya was grounded on a grinding machine for the purpose.
The matter that was removed from Surya fell on earth and from it was created the Pushpaka Vimanam – the flying machine.
Vishwakarma created the Pushpaka Vimana and presented it to Kubera – the treasurer of Gods. Later it came into the possession of Ravana.
