Area 51, Nevada, is a focus of unidentified flying object theories because of reports of strange phenomena, and its secretive nature.  The center for classified aircraft research, it is also known as Dreamland, Groom Lake, Paradise Ranch, Home Base and Honey Airport.

Area 51  is located in the Nevada desert about 95 miles from Las Vegas.  It includes the Nellis Air Force Base’s bombing and gunnery range.  It is alleged that there is a research facility 15 miles from the center of Area 51 called S-4.  This is where Bob Lazar claimed to work in the 1980s.

Physicist Lazar is one of the most famous names associated with Area 51.  He claims the United States government employed him to help figure out how UFOs work.  He said that alien spacecraft are being housed at S-4.  Lazar produced a pay slip to support his contention that he worked at Area 51.  Some of his claims stack up.  He fits into UFO conspiracy theories.

Lazar contends that when he arrived at Area 51,  he received a briefing document.  This document stated that alien life forms did exist and had been blended into human evolution.  Bob Lazar claims that while he was at S-4, some of the Element 115 disappeared.  Scientists at the facility suspected that Element 51 was the fuel that propels UFOs, and would like to blend Element 115 with Earth materials to create a super fuel.

Alien technology is stored at S-4 to be studied. 

Soviet scientists were allowed to participate in the program, but after the disappearance of the Element 115, they were kicked out.  Guns were issued to the remaining scientists

Area 51 seems to be a center of classified aircraft research.  S-4 appears to be the center of more exotic research.  It is possible that alien technology and spacecraft are researched there.
