None of this occurs with flying discs which are propelled by diamagnetism, i.e., etheric forces. It goes without saying that Flying Saucers encounter no heat barrier since they generate a negative pressure and diamagnetism, Their metal or glass air frames are no more heated than the shell of an implosion engine. On the contrary, they cool to their specific zone of anomaly. It would be impossible to imagine more perfect air vehicles. They have no sound barrier, no heat barrier, and they require no costly propellant because they generate their own motive power, that is diamagnetism. THE UNIVERSAL SOURCE OF ENERGY An abundance of this energy, Diamagnetism, is available throughout the universe. Therefore, such a diamagnetic aircraft could travel around the earth not once, but two or three times at any given altitude without having to refuel. Actually, it could travel in outer space for years, or as long as the crew did not have to replenish its food supplies. The following observations may serve as proof that the Fly- ing Saucers are diamagnetically propelled. As already mentioned in our chapter on diamagnetism, copper is a diamagnetic metal. When the UFO's fly at a relatively low rate of speed, they are surrounded by a light greenish hue. The spectral line, of burning copper has been observed to fall within this specific green. Furthermore, air samples taken from the atmosphere in the regions where, beginning in 1947, the UFOs have been frequently observed, have shown high concentrations of copper particles in very fine dispersion. On the other hand, air samples taken before the appearance of the Flying Saucers, show a complete absence of copper. Of course, none of the observations made so far regarding the UFO's speed, performance, take-off characteristics, and various light effects can be brought in line with the familiar laws of physics. This, however, is no proof that unknown types of air vehicles can not exist. After all, the mechanism of implosion and the nature of diamagnetism are ignored in modern physics and remain to be investigated and formally clarified.
