Sector-4

S-4 (Sector Four) is said to be located at Papoose Lake, in the Restricted Air Force base, Area 51. The site came to public attention when Bob Lazar spoke about working at the site and working on circular disc shapes from other worlds. Nine hangars featuring 9 different shaped crafts are said to be featured there.

According to Lazar, S-4 consists of 9 hangers built into a mountain range just off the Papoose Lake bed. The hangars are sloped at 60 degrees and are camoflauged to blend in with the mountainside. S-4 also contains a number of interior shopping areas in addition to the hangars, such as a briefing room, a laboratory, a nurse's office, a restroom and the entrance area.

Although the hangars at S-4 contained 9 extraterrestrial craft, Lazar only had close contact with one such craft, which he nicknamed the "Sports Model". The sizes and shapes of the ET crafts at S-4 varied considerably. The Sports Model had the appearance of a classic flying saucer, while some of the other ET crafts looked like a top hat or a Jello mold.

Personnel working at S-4 would reach the base by first arriving at Groom Lake and then taking a bus to the installation via a very long and winding dirt road. Once the bus reached S-4, the bus would drive the length of the hangars and then park at the entrance area, located at the back of the installation. Lazar claims that at one time Russian scientists worked at the base, but were kicked out.

In November of 1989 Robert Scott Lazar gave a series of interviews to George Knapp on KLAS-TV in Las Vegas. Lazar claimed that while employed as a physicist by the U.S. government, he had worked on a super-secret project located in the restricted Nellis Range near Rachel, Nevada just south of the famous "Area 51."
