Bob Lazar speaks with the measured calm of a man who has long since made peace with disbelief. Seated across from our correspondent in an undisclosed location, he does not flinch, does not embellish. He recounts the events of the late 1980s as a physicist might describe a laboratory procedure: matter-of-factly, with an almost unnerving absence of drama.
"I worked at a site designated S-4," he says. "It was a facility built into the mountainside, south of the main Groom Lake complex. The hangars were wedge-shaped, flush against the rock. Inside were nine disc-shaped craft of non-human origin. My assignment was to understand and replicate the propulsion system."
The propulsion, Lazar explains, was based on an element he had never encountered in any terrestrial periodic table — what he would later call Element 115, Moscovium, now officially confirmed by the scientific community in 2003 and added to the periodic table in 2016. At the time, his knowledge of its existence was itself evidence, detractors would concede, of something extraordinary.
