On November 11 and 13, 1989, viewers of KLAS-TV in Las Vegas, Nevada, heard an incredible story from news reporter George Knapp: A scientist named Bob Lazar had come forth to reveal that the U.S. government possesses the remains of extraterrestrial vehicles. From these vehicles have come extraordinary technological breakthroughs.
A government physicist, Bob Lazar said he had worked in the S-4 section the formerly secret military base known as Area 51, a corner of the Nevada Test Site. There, he had read documents indicating the existence of ongoing research on an "anti-gravity reactor" for use in propulsion systems.
He was astonished, he said, but he was even more shocked to be shown nine flying discs "of extraterrestrial origin" stored in a hangar. As part of the gravity-harnessing propulsion, the craft used an element, 115, unknown on Earth, because it is "impossible to synthesize an element that heavy here on Earth. ... The substance has to come from a place where super-heavy elements could have been produced naturally." From the recovered craft the U.S. government had collected some 500 pounds of the stuff.
Adding apparent credibility to Lazar's testimony were persistent reports (chronicled even in the respected Aviation Week & Space Technology) of bizarre lights over the test site-craft maneuvering in ways beyond the capacity of known aviation technology. These reports are almost certainly genuine.
