The retired physics professor Auguste Meessen [1] has studied the UFO phenomenon since the late 1960s. From witness reports, he concluded that these craft must use an electromagnetic propulsion system [2]. He then developed the Pulsed ElectroMagnetic Propulsion (PEMP) system [3]. The principle is that the vehicle generates an intense alternating magnetic field and ionises the surrounding air at precisely the right time and location. This produces a Lorentz force which, by reaction, propels th...
