“It all comes down to standard physics. An electromagnetic field can create a low pressure area under an aerodyne, or flying saucer. To this can be related the peculiar property of plasma. Plasma’s magnetic field is frozen inside while it expands at unimaginable speeds, producing an electrical current. Using plasma, a belt of “free air’ can be created. The molecules of air in front of this belt are pushed aside without piling on top of each other, as they do when a normal aerofoil passes through the atmosphere fast enough to break the sound barrier.
