Elklick Woodlands Natural Area Preserve is a 226-acre (91 ha) Natural Area Preserve located in Fairfax County, Virginia. Owned by the Fairfax County Park Authority, it is protected with a local conservation easement, and preserves a globally rare natural community known as a "northern hardpan basic oak-hickory forest". This kind of forest occurs on diabase soil with an underlay of dense plastic clay; such terrain is called "shrink-swell soil" due to extreme variations in moisture availability exhibited throughout the year. Trees which grow in such an environment are stunted, and their relatively open canopies encourage the growth of a wide variety of grasses and herbs in the understory. Such forests were once common around northern Virginia, but many have been lost due to increasing suburbanization of the area.The forest found within Elklick Woodlands Natural Area Preserve is one of the most diverse upland forests types in Virginia. The forest's overstory is composed of several species of oaks (particularly white oak) and hickories (particularly pignut hickory); other canopy trees include white ash, tulip poplar, eastern red cedar, and Virginia pine. These trees are somewhat stunted and reach heights that are, on average, about 20 feet (6.1 m) shorter than typical forest trees in the region. The understory contains redbud, ironwood, flowering dogwood, and hawthorn.The preserve is owned and maintained by the Fairfax County Park Authority. It does not include improvements for public access, and visitors must make arrangements with the Fairfax County Park Authority prior to visiting. The preserve is part of a larger tract of county-owned parkland known as the Elklick Preserve. It is continuous with other county-owned and privately conserved greenspace, as well as the nearby Manassas National Battlefield Park.

The National Reconnaissance Office (NRO) is a member of the United States Intelligence Community and an agency of the United States Department of Defense which designs, builds, launches, and operates the reconnaissance satellites of the U.S. federal government, and provides satellite intelligence to several government agencies, particularly signals intelligence (SIGINT) to the NSA, imagery intelligence (IMINT) to the NGA, and measurement and signature intelligence (MASINT) to the DIA.NRO is considered, along with the Central Intelligence Agency (CIA), National Security Agency (NSA), Defense Intelligence Agency (DIA), and National Geospatial-Intelligence Agency (NGA), to be one of the "big five" U.S. intelligence agencies. The NRO is headquartered in Chantilly, Virginia, 2 miles (3.2 km) south of the Washington Dulles International Airport. The Director of the NRO reports to both the Director of National Intelligence and the Secretary of Defense. The NRO's federal workforce is a hybrid organization consisting of some 3,000 personnel including NRO cadre, Air Force, Army, CIA, NGA, NSA, Navy and US Space Force personnel. A 1996 bipartisan commission report described the NRO as having by far the largest budget of any intelligence agency, and "virtually no federal workforce", accomplishing most of its work through "tens of thousands" of defense contractor personnel.

The Enola Gay () is a Boeing B-29 Superfortress bomber, named after Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets. On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb in warfare. The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused the destruction of about three quarters of the city. Enola Gay participated in the second nuclear attack as the weather reconnaissance aircraft for the primary target of Kokura. Clouds and drifting smoke resulted in Nagasaki, a secondary target, being bombed instead. After the war, the Enola Gay returned to the United States, where it was operated from Roswell Army Air Field, New Mexico. In May 1946, it was flown to Kwajalein for the Operation Crossroads nuclear tests in the Pacific, but was not chosen to make the test drop at Bikini Atoll. Later that year, it was transferred to the Smithsonian Institution and spent many years parked at air bases exposed to the weather and souvenir hunters, before its 1961 disassembly and storage at a Smithsonian facility in Suitland, Maryland. In the 1980s, veterans groups engaged in a call for the Smithsonian to put the aircraft on display, leading to an acrimonious debate about exhibiting the aircraft without a proper historical context. The cockpit and nose section of the aircraft were exhibited at the National Air and Space Museum (NASM) on the National Mall, for the bombing's 50th anniversary in 1995, amid controversy. Since 2003, the entire restored B-29 has been on display at NASM's Steven F. Udvar-Hazy Center. The last survivor of its crew, Theodore Van Kirk, died on 28 July 2014 at the age of 93.

The Steven F. Udvar-Hazy Center, also called the Udvar-Hazy Center, is the Smithsonian National Air and Space Museum (NASM)'s annex at Washington Dulles International Airport in the Chantilly area of Fairfax County, Virginia. It holds numerous exhibits, including the Space Shuttle Discovery, the Enola Gay, and the Boeing 367-80, the main prototype for the popular Boeing 707 airliner. The 760,000-square-foot (71,000 m2; 17-acre; 7.1 ha) facility was made possible by a $65 million donation in October 1999 to the Smithsonian Institution by Steven F. Udvar-Házy, an immigrant from Hungary and co-founder of the International Lease Finance Corporation, an aircraft leasing corporation. The main NASM building, located on the National Mall in Washington, D.C., had always contained more artifacts than could be displayed, and most of the collection had been stored, unavailable to visitors, at the Paul E. Garber Preservation, Restoration, and Storage Facility in Silver Hill, Maryland. A substantial addition to the center encompassing restoration, conservation and collection-storage facilities was completed in 2010. Restoration facilities and museum archives were moved from the museum's Garber facility to the new sections of the Udvar-Hazy Center.
