Bob Lazar is a former government physicist who made headlines world-wide in 1989 when he came forward via investigative reporter George Knapp with his account of reverse-engineering an alien propulsion system for the U.S. military.
Lazar claims to have worked during the years 1988 and 1989 as a physicist at a site called S4, near the now famous Area 51 test facility in Nevada. According to Lazar, S4 served as a hidden military location for the study and research of extraterrestrial spacecraft, or flying saucers. Lazar claims he saw nine different extraterrestrial vehicles at the facility, and has provided detailed information on the mode of propulsion and other technical aspects of a disc-shaped vehicle he called the sport model. He also claims to have been working with the exotic fuel, an element with an atomic number of 115 which allows the space crafts to warp time/space—and essentially pull the desired destination toward the ship. This method of travel is said to allow for the crossing of vast distances almost instantaneously.
Lazar currently runs a scientific equipment and supply company out of Laingsburg, MI, called United Nuclear.
