 [This fragment sample] was recovered by two witnesses of an aerial phenomenon. Although the material appears to be common tungsten carbide, the original shape of the specimen was unusual and it has not been identified as an object serving a conventional use. 

According to a summary of the case compiled by Von Ludwiger (1998), the two witnesses, Stig Ekberg and Harry Sjoberg, were building a house on the island of Vaddo, about 90 kilometers north-northwest ofStockholm. At about 10 p.m., Ekberg was driving his Ford V8 pickup when they saw a bright flying object with the shape of a flattened sphere 8 meters wide and 3 meters high approaching from the right (from the east) against the clear night sky. They estimated that it flew about 1 kilometer in front of them at an altitude of 100 meters. Suddenly it made a sharp turn toward them, at which time the truck engine sputtered and died and the headlights went out. The object started “slowly gliding down.” It seemed to rock back and forth until it came to a stop in the middle of the road, about 100 meters in front of them, 1 meter above the ground. “It was illuminating the surrounding landscape with such a tremendous amount of light that even a barn, half a kilometer away, was visible as if the sun was shining.” The air smelled like ozone and smoldering insulation.

After about ten minutes the light of the object intensified, it lifted off the ground, moved to the left and up, made a sudden turn, and accelerated away in the direction from which it came. At that point Ekberg was able to restart the truck normally, and the headlights came back on. Observing that the grass at the landing site had been flattened, they investigated further and found a shiny “rock” that was hot to the touch. It was a three-sided piece of metal about the size of a matchbox, and had a heavy weight.

After several unsuccessful attempts to have the sample studied, it was taken to the SAAB airline manufacturing company, where Mr. Sven Schalin conducted a thorough analysis. Other tests were later run in laboratories in Sweden, Denmark, and Germany. The general conclusion was that the object was composed of tungsten carbide and cobalt, consistent with manufactured products. According to Von Ludwiger, “All industrial countries have companies which produce such hard metals, and the manufacturing technology is in principle the same. . . . The overall quality of the material was outstanding, but not unusual for the early 1950s.”
