Currently at the Smithsonian, ancient South American artifacts resembling airplanes or winged insects were found in a number of places including a grave. The small artifacts are made of gold, which means that conventional dating methods won’t work on them.
Even though archeologists admit that they don’t know how old they are, it can safely be assumed from their surroundings, including other “dateable” artifacts, that they are a minimum of 1000 years old.
For a number of years, a disagreement has “raged” over the “meaning” of the artifacts. Archaeologists labeled these objects as “zoomorphic”, meaning, animal shaped objects.
In 1995, a model of one the Ã¢â¬Ågolden planesÃ¢â¬Â was reconstructed. The result was that the object did correspond to the aerodynamic demands of modern airplanes.
Peter Belting, a German pilot and model-airplane builder, proved this result in an experiment with his colleagues Dr. Algund Eenboom and Conrad LÃÂ¼bbers.
They built the antique artifacts as airplane-models with radio guidance. The models were approximately 1 meter from tip to tip and were able to perform a complete programme: loops, rolls, takeoff and landings, without aerodynamic problems.

Today’s aspherically ground glasses for high precision optical instruments are generally held to be an achievement of our highly technological world, a product of the computer age. A mistaken view. Actually, the first such instruments date back to the 12th century. After several years of painstaking analyses, eyeglass experts have now confirmed that the ground rock crystal objects from the 12th century found in Swedish Viking graves were made almost to perfection.
If the lens is placed on a text page, the effect is the same as that obtained with a modern magnification glass measuring 5cm in diameter. It was not until the 17th century that mathematician RenÃÂ© Descartes successfully made theoretical calculations about aspherical lenses.
However, this precision technology was not known to have been used in practice before the 20th century. So how did they develop such sophisticated optical devices 8 centuries ago? Researchers from the University of California at Berkeley now want to further investigate the sensational “Viking” lenses.
It is generally believed that the unusual items were originally manufactured in Byzantium, where they were purchased or stolen by the Vikings.
