Aircraft, UFO, flying machine, ionic engine, nuclear reactor, ionic particles, accelerated particles, a circular particles accelerator, jets of ions with high velocities, galaxy, high distances.
There are real aircrafts who look like a flying saucer, but the most UFO cases (related cases) have been some illusions. A real flying saucer is an aircraft (a flying machine) with an ionic engine. The flying ship has a nuclear reactor which generates nuclear particles (ionic particles). These particles must be accelerated with a circular (flying) particles accelerator. The aircraft is a real particles accelerator (a flying circular ions accelerator). The nuclear accelerated particles are evacuating in jets with high velocities. These jets move the flying ship. The aircraft movement is opposing at the jet direction. With an aircraft acted by an ionic engine we may traverse the galaxies and one can win the distances and the time as well.
