THERE WAS A SCIENTIST that built a VIMANA to these specifics, right down to the Mercury Engines.
It flew to a height of 1500 feet before crashing down to earth.
This was 180 years ago!
The Indian Emperor ASHOKA ordered the secrets of building VIMANAS and other ancient Indian Science be CATALOGUED and HIDDEN from Man...He was afraid of another ATOMIC WAR like the one described in THE MAHABHARATA.
Believe it or not, Folks, the CHINESE SPACE AGENCY first consulted with VIMANIC DOCUMENTS before starting their Space Program!
Alexander the Great described being attacked fleeting by VIMANAS that flew off after a half-hearted attempt at impeding his army's progress.
What is the secret of FLIGHT employed here?
NOT FLIGHT at ALL!
Somehow, the mercury engines can cancel or allow one to control the effects of GRAVITY.....
Go ahead, give it a try....
But don't blame me if you meet with MISCHIEF!
