What we appear to have here is an explanation for the German Foo-Fighters which were recorded during World War II and which seemed to fly of their own power and volition. This may or may not be so but Landzig may well have known about these and if so knew their origins. These seem to be a 'representation of the morphogenetic grid' which has something to do with what is called the Morphogenetic Field. This is simply a blueprint that stores information form how something is formed - like a 'blueprint' for the human shape or parts of the body etc. At least that is how I understand the concept. The Morphogenetic Grid, I am assuming, is linked to the Earth-Grid (Grid is an Earth-Giantess) and to Sacred Geometry.
These are 'fourth-dimensional interfaces with the Life-Force itself'; that is, this stems directly from the Life-Force of the Cosmos. They have something to do with what is called Thought-Forms (Tulkas) which are projected, vessels of creation. The power to manifest these appears to be what is called the Vril-Force.
This gives an explanation as to what the 'Balls of Light' are in the field of UFOs; these are not the 'Flying Saucers' spoken of by Viktor Schauberger and the sightings of these over the past few decades. They may be the 'Balls of Light' seen over the fields that have produced Crop-Circles; these have been photographed as one crop-circle was being made. I have myself witnessed a 'Ball of Light' passing across the skies at the time of the Hale-Bopp Comet. This was certainly not a 'Flying Saucer' but obviously a 'Ball of Light'; we have to distinguish between the two.
In the book the flying machines used to transport the subjects of the book are called by the name 'V-7' and referred to as a 'Spinning Disc'. Here we are in the realms of a physical spinning saucer-shaped disc. A flight to Prague is done in a Dostra Maschine which is some 45 metres long and made of Quettschmetall or 'crimp-metal' which is a highly compressed metal. This can do 830 kilometres per hour.
