Nikola Tesla, inventor of alternating current motors, did the basic research for constructing electromagnetic field lift-and-drive aircraft/space craft. From 1891 to 1893, he gave a set of lectures and demonstrations to groups of electrical engineers.
As part of each show, Tesla stood in the middle of the stage, using his 6′ 6″ height, with an assistant on either side, each 7 feet away. All 3 men wore thick cork or rubber shoe soles to avoid being electrically grounded. Each assistant held a wire, part of a high voltage, low current circuit.
When Tesla raised his arms to each side, violet colored electricity jumped harmlessly across the gaps between the men. At high voltage and frequency in this arrangement, 
electricity flows over a surface, even the skin, rather than into it. This is a basic circuit which could be used by aircraft / spacecraft.
The hull is best made double, of thin, machinable, slightly flexible ceramic. This becomes a good electrical insulator, has no fire danger, resists any damaging effects of severe heat and cold, and has the hardness of armor, besides being easy for magnetic fields to pass through. Read more….
