Map showing Area 51, NAFR, and the NTS
Area 51 is a section of land of approximately 60 sq. mi. / 155 kmē in Lincoln County, Nevada, USA. It is part of the vast (4687 sq. mi. / 12139 kmē) Nellis Air Force Range (NAFR). The area consists largely of the wide Emigrant Valley, framed by the Groom and Papoose mountain ranges (to the North
and South respectively) and the Jumbled Hills to the East. Between the two ranges lies Groom Dry Lake (37°16′05″N, 115°47′58″W), a dry alkali lake bed roughly three miles (5 km) in diameter. A large air base exists on the southwest corner of the lake (37°14′N 115°49′W) with two concrete runways, one of which extends onto the lake bed, and four unprepared runways on the lake bed itself.
High-resolution satellite images have shed some light on the facility's complex runway layouts. Area 51 has two operating
runways, the main is 14L/32R, a concrete runway constructed in the 1990s, measuring 11,980 x 200 ft (3651 x 61 m) with a 1000
x 100 ft (304 x 30 m) overrun at each end and the secondary, shorter runway is 12/30 which also doubles as a taxiway, measuring
5,420ft x 150ft (1,652m x 45m). The older runway is exactly six miles (9656 m) long. It is composed of 12,500 ft of concrete,
11,080 ft of asphalt, and 5560 ft and 2540 ft of now dismantled asphalt on the north and south ends respectively. At least
three sets of old runway markings are found, suggesting that the full six-mile length was probably never used in its entirety.
Currently only a 6,600 ft (2011 m) stretch of the concrete section is marked for use, forming runway 14R/32L. The dirt lakebed
runways, comprising two twin airstrips, measure up to 11,270 ft (3435 m) in length and 100 to 170 ft (30 to 52 m) in width.
Area 51 shares a border with the Yucca Flats region of the Nevada Test Site (NTS), the location of many of the U.S. Department of Energy's nuclear weapons tests. The Yucca Mountain nuclear storage facility is approximately 40 miles (64km) southwest of Groom Lake.
The designation "Area 51" is somewhat contentious, appearing on older maps of the NTS but not newer ones, but the same
naming scheme is used for other parts of the Nevada Test Site.
The area is connected to the internal NTS road network, with paved roads leading both to Mercury to the northwest and west
to Yucca Flats. Leading northeast from the lake, Groom Lake Road (a wide, well-conditioned dirt road) runs through a pass
in the Jumbled Hills. Groom Lake Road was formerly the track leading to mines in the Groom basin, but has been improved since
their closure. Its winding course takes it past a security checkpoint, but the restricted area around the base extends further
east than this (unauthorized visitors who travel west on Groom Lake Road are usually observed first by guards located on the
hills surrounding the pass, still several miles from the checkpoint). After leaving the restricted area (marked by numerous
warning signs stating that "photography is prohibited" and that "use of deadly force is authorized") Groom Lake Road descends
eastward to the floor of the Tikaboo Valley, passing the dirt-road entrances to several small ranches, before joining with
Nevada State Route 375, the "Extraterrestrial Highway", south of Rachel.
Operations at Groom Lake
Groom Lake is not a conventional airbase, and frontline units are not normally deployed there. It appears, rather, to be
used during the development, test and training phases for new aircraft. Once those aircraft have been accepted by the United States Air Force, operation of that aircraft is generally shifted to a normal air force base. Groom is reported, however, to be the permanent
home for a small number of aircraft of Soviet design (obtained by various means). These are reportedly analyzed and used for training purposes.
Soviet spy satellites obtained photographs of the Groom Lake area during the height of the Cold War, but these support
only modest conclusions about the base. They depict a nondescript base, airstrip, hangars, and so forth, but nothing that
supports some of the wilder claims about underground facilities. Later commercial satellite images show that the base has
grown, but remains superficially unexceptional.
Senior Year / U-2 program
Groom Lake was used for bombing and artillery practice during World War II, but was then abandoned until 1955, when it was selected by Lockheed's skunkworks team as the ideal location to test the forthcoming U-2 spy plane. The lakebed made for an ideal strip to operate the troublesome test aircraft from, and the Emigrant Valley's mountain
ranges and the NTS perimeter protected the secret plane from curious eyes.
Lockheed constructed a makeshift base at Groom, little more than a few shelters and workshops and a small constellation
of trailer homes in which to billet its small team. The first U-2 flew at Groom in August 1955, and U-2s under the control
of the CIA began overflights of Soviet territory by mid-1956.
During this period, the NTS continued to perform a series of atmospheric nuclear explosions. U-2 operations throughout
1957 were frequently disrupted by the Plumbbob series of atomic tests, which exploded over two dozen devices at the NTS. The Plumbbob-Hood explosion on July 5 scattered fallout across Groom and forced its (temporary) evacuation.
As the U-2's primary mission was to overfly the Soviet Union, it operated largely from airbases near the Soviet border,
including Incirlik in Turkey and Peshawar in Pakistan.
Blackbird (OXCART / A-10 / A-11 / A-12 / SR-71) program
Even before U-2 development was complete, Lockheed began work on its successor, the CIA's OXCART project, a Mach-3 high altitude reconnaissance aircraft later known as the SR-71 Blackbird. The Blackbird's flight characteristics and maintenance requirements forced a massive expansion of facilities and runways
at Groom Lake. By the time the first A-12 Blackbird prototype flew at Groom in 1962, the main runway had been lengthened to
8500 ft (2600 m), and the base boasted a complement of over 1000 personnel. It had fueling tanks, a control tower, and a baseball diamond. Security was also greatly enhanced, the small civilian mine in the Groom basin was closed, and the area surrounding
the valley was made an exclusive military preserve (where interlopers were subject to "lethal force"). Groom saw the first
flight of all major Blackbird variants: A-10, A-11, A-12, RS-71 (renamed SR-71 by USAF Chief of Staff Curtis LeMay and not by a presidential error as popularly believed), the abortive YF-12A strike-fighter variant, and the disastrous D-21
Blackbird-based drone project.
Have Blue / Senior Trend / F-117 program
The first Have Blue prototype stealth fighter (a smaller cousin of the F-117 Nighthawk) first flew at Groom in late 1977. Testing of a series of ultra-secret prototypes continued there until mid-1981, when testing
transitioned to the initial production of F-117 stealth fighters. In addition to flight testing, Groom performed radar profiling,
F-117 weapons testing, and was the location for training of the first group of frontline USAF F-117 pilots. Subsequently active-service
F-117 operations (still highly classified) moved to the nearby Tonopah Test Range and finally to Holloman Air Force Base.

Since the F-117 became operational in 1983, operations at Groom Lake have continued unabated. The base and its associated
runway system have been expanded, and the daily flights bringing civilian commuters from Las Vegas continue. Some commentators,
after examining recent satellite photos of the base, estimate it to have a live-in complement of over 1000 people, with a
similar number commuting from Las Vegas. In 1995 the federal government expanded the exclusionary area around the base to
include nearby mountains that had hitherto afforded the only decent overlook of the base. Subsequently, limited views of the
area are available only from the summits of several distant mountains, particularly Tikaboo Peak (37°20′40″N, 115°21′32″W), around 26 miles (42 km) to the east.
Rumored aircraft that have supposedly been tested at Groom include the various classified UAVs, a small stealthy VTOL troop-transport aircraft, a stealthy cruise missile, and the hypothetical Aurora hypersonic spy plane. Some also claim the initial testing of the Northrop Tacit Blue stealth demonstrator aircraft was conducted at Groom.
Area 51 commuters
EG&G JANET 737s at McCarran.
Defense contractor EG&G maintains a private terminal at McCarran International Airport in Las Vegas. A number of unmarked aircraft operate daily shuttle services from McCarran to sites operated by EG&G in the extensive
federally controlled lands in southern Nevada. These aircraft reportedly use JANET radio call signs (e.g., "JANET 6"), said
to be an acronym for "Joint Air Network for Employee Transportation" or (perhaps as a joke) "Just Another Non-Existent Terminal".
EG&G advertises in the Las Vegas press for experienced airline pilots, saying applicants must be eligible for government
security clearance and that successful applicants can expect to always overnight at Las Vegas. These aircraft, painted white
with red trim (the livery of now defunct Western Airlines), include Boeing 737s and several smaller executive jets. Their tail numbers are registered to several unexceptional civil aircraft leasing corporations.
They are reported to shuttle to Groom, Tonopah Test Range, to other locations in the NAFR and NTS, and reportedly to Naval Air Weapons Station China Lake. Observers counting departures and cars in the private EG&G parking lot at McCarran estimate several thousand people
commute on JANET each day.
A bus runs a commuter service along Groom Lake Road, catering to a small number of employees living in several small desert
communities beyond the NTS boundary (although it is not clear whether these workers are employed at Groom or at other facilities
in the NTS). The bus drives down Groom Lake Road and stops at Crystal Springs, Ash Springs, and Alamo.
The Government's position on Area 51

The U.S. government does not explicitly acknowledge the existence of the Groom Lake facility, nor does it deny it. Unlike
much of the Nellis range, the area surrounding the lake is permanently off-limits both to civilian and normal military air
traffic. The area is protected by radar stations, and uninvited guests are met by helicopters and armed guards. Should they
accidentally stray into the exclusionary "box" surrounding Groom's airspace, even military pilots training in the NAFR are
reportedly grilled extensively by military intelligence agents.
Perimeter security is provided by uniformed private security guards working for EG&G, who patrol in desert camouflage
Jeep Cherokee and Hum-Vee vehicles. Although the guards are armed with M16s, no violent encounters with Area 51 observers have been reported; instead the "camo dudes" generally follow visitors near
the perimeter and radio for the Lincoln County sheriff. Modest fines (of around $600) seem to be the norm, although some visitors
and journalists report receiving follow-up visits from FBI agents. Some observers have been detained on public land for pointing camera equipment at the base. Surveillance is also
conducted using buried motion sensors and by HH-60 Pave Hawk helicopters.
The base does not appear on public U.S. government maps; the USGS topological map for the area only shows the long-disused
Groom Mine, and the civil aviation chart for Nevada shows a large restricted area, but defines it as part of the Nellis restricted
airspace. Similarly the National Atlas page showing federal lands in Nevada does not distinguish between the Groom block and other parts of the Nellis range. Although officially declassified, the original
film taken by U.S. Corona spy satellite in the 1960s has been altered prior to declassification; in answer to freedom of information queries, the government responds
that these exposures (which map to Groom and the entire NAFR) appear to have been destroyed (Corona image). Terra satellite images (which were publicly available) were removed from webservers (including Microsoft's "Terraserver") in 2004
