After a good deal of research, I have been of the train of thought that many of the UFO sightings are not actually UFOs, but are human built X Craft. These X Craft utilize an advanced antigravity type of propulsion, usually termed Magneto-hydrodynamic and/or electrogravitic propulsion.

Some believe that this technology was obtained from reverse engineering alien technology from retrieved crashed UFOs.

I do not agree with this point of view, and believe that this technology was the brainchild of Nikola Tesla, and originated around the 1880s, and only in the past 40 years has been developed into usable technology.

The following excerpts come from the book "The Lost Journals of Nikola Tesla" by Tim Swartz.

At high voltage and frequency, electricity flows over a surfac, even human skin, rather than into it. This is a base 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 hazard, and has the hardness and strength of armor, besides being transparent to magnetic fields.

The inner hull is covered on its outsides by wedge shaped thin metal sheets of copper or aluminum, bonded to the ceramic. Each sheet is three to four feet wide at the horizontal rim of the hull and tapers to a few inches wide at the top of the hull for the top set of sheets, or at the bottom for the bottom set of sheets. Each sheet it separated on either side from the next sheet by a couple inches of uncovered ceramic hull.

The top set of sheets and the bottom set of sheets are separated by about 6 inches of uncovered ceramic hull around the horizontal rim of the hull. The outer hull protects these sheets from being short circuited by rain or other contaminants.

In space, the outer hull with a slight negative charge would absorb hits from micro meteorites and cosmic rays. If any object doesnt already have a negative charge, it would obtain one on impact with the outer hull, and be repelled by the positively charged inner metal sheets before it could penetrate the inner hull.

The hull can be made in a variety of shapes: sphere, football, disc, streamlined, or triangle, as long as the metal sheets are of considerable area and arranged along the enveloping surfaces of very large radii of curvature.

Electricity is fed into a number of capacitors, one for each metal sheet. An automatic switch closes and the electricity is raised in frequency by a transformer. The electricity comes out of the transformer at the high voltage end and goes by wire through the ceramic hull to the wide end of the metal sheet. The electricity arcs out on and flows over the metal sheet, giving off a very strong magnetic field, controlled by the transformer. At the narrow end of the metal sheet, most of the high voltage push having been given off, the electricity goes back by wire through the hull to a circuit breaker.

In bright sunlight, the aircraft/spacecraft may seem surrounded by hot air, a slight magnetic distortion of the light. In darkness the metal sheets glow, even through the thin ceramic outer hull, with different colors. The visible light is a by product of the electricity flowing over the metal sheets according to the frequencies used.

Timing is important in the operation of the machine. For every three metal sheets, when the middle one is briefly turned off, the sheet on either side is energized, giving off the magnetic field. The next instant, the middle sheet is energized while the sheet on either side is turned off briefly, to allow the capacitors to recharge.

There is a time delay in the capacitors recharging themselves, so that at any given time half of all the metal sheets are active and half are charging, alternating around the hull. This balances the machine, giving it very good stability. This balance is less when fewer of the circuits are in use.
