One night in May 1989, a reporter broadcast a story from a satellite link in Las Vegas Nevada.  A young physicist spoke under hidden identity and told us of 9 alien discs held near Groom Lake by a small, autonomous group of the American government.  He used the pseudonym "Dennis" -- which turned out to be the name of his superior at the base.  A few weeks later, he went on camera using his real name -- Bob Lazar -- and he has been the subject of worldwide curiosity, speculation, and controversy ever since. 
The following pages are the result of over 5 years work in an effort to recreate and illustrate the scientific aspects of an interstellar craft and the physics of its propulsion system.  This is a biography in database form, of the events and statements of Bob Lazar.  The result is the most complete collection of information to date regarding this subject.
Prior to Lazar's appearance in the media, Soviet satellites were photographing the Area-51/S4 area 3 times a month. After Lazar appeared on television revealing information about the project, the Soviets began photographing the Papoose lake region and S4 almost daily.
Basically, the satellite snapped a picture through filters and exposed the image on a single 12" square sheet of film.  A canister containing a roll or completed magazine was jettisoned to Earth.  Groom Lake was the primary interest to this satellite when covering the Nevada area.  An interest due in part to the Stealth and SR-71 projects which were built and tested at Groom Lake.  With Lazar coming forward and identifying S4 in 1989, the surveillance from this particular satellite increased from one every 2 weeks to one aday .  Actually, thealien technology wasn't housed at Area-51 at all but rather 15 miles south of Groom Lake at the Papoose dry lakebed.
