The Aurora Highlands Historic District is a national historic district located at Arlington County, Virginia. It contains 624 contributing buildings, 2 contributing sites, and 1 contributing structure in a residential neighborhood in South Arlington. Aurora Highlands was formed by the integration of three subdivisions platted between 1896 and 1930, with improvements in the form of modest single-family residences. The district is characterized by single family dwellings with a number of twin dwellings and duplexes, three churches, a rectory, two schools, two landscaped parks, and commercial buildings. The oldest dwelling is associated with “Sunnydale Farm” and is a Greek Revival-style dwelling built about 1870. The predominant architectural style represented is Colonial Revival.In the early 1970s, spillover commuter parking in Aurora Highlands by workers at the adjacent Crystal City complex led the county to establish the first residential zoned parking in the U.S. with the goal of reducing air pollution and protecting the neighborhood character as well as its quality of life. A lawsuit was filed to block it as a violation of the Equal Protection Clause of the Fourteenth Amendment. The plaintiffs prevailed in trial court and then on appeal to the Virginia Supreme Court, which held it unconstitutional since it granted residents of the permit zone greater rights over the public streets than their neighbors outside of it. The county appealed to the U.S. Supreme Court, which reversed the lower courts in Arlington County Board v. Richards, holding that discrimination based on residency alone was not unconstitutional if it rationally furthered a legitimate state interest such as those embraced by the ordinance.It was listed on the National Register of Historic Places in 2005.

Prospect Hill in Arlington County, Virginia is the former location of a Federal style mansion built in 1841 by successful contractor James Roach in Arlington County (then named Alexandria County). The house was built on Arlington Ridge Road. In 1861, the land was seized and vandalized by Union soldiers during the construction of Fort Runyon and Fort Albany. The house was demolished in 1965, but an historic marker has been placed at the site. Roach had also supplied most of the materials for the Alexandria Canal, the Aqueduct Bridge, and the Alexandria, Loudoun and Hampshire Railroad.After the September 11 attacks, Prospect Hill became a popular spot for photographs to take photos of The Pentagon after it was crashed into by American Airlines Flight 77.The site is also home to the 0.4 acre Prospect Hill Park.

Fort Albany was a bastioned earthwork that the Union Army built in Arlington County (known at the time as Alexandria County) in Virginia. The Army constructed the fort during May 1861 as part of its Civil War defenses of Washington (see Washington, D.C., in the American Civil War).The fort had a perimeter of 429 yards and emplacements for 12 guns.Fort Richardson, Fort Craig and Fort Tillinghast provided supporting fire for the fort. A May 17, 1864, report from the Union Army's Inspector of Artillery (see Union Army artillery organization) noted the following:Fort Albany, Captain Rhodes commanding.–Garrison, one company First Massachusetts Volunteers–5 commissioned officers, 1 ordnance-sergeant, 145 men. Armament, two 24-pounder field howitzers, four 24-pounder siege, two Parrotts, one Coehorn mortar, one 10-inch mortar. Magazines, two; dry and in good order. Ammunition, full supply and in good condition. Implements, complete and in good order. Drill in artillery, fair. Drill in infantry, fair. Discipline, fair. Garrison of sufficient strength. No trace of the fort remains, although a historic marker shows the location where the fort once stood, guarding the approach to the Long Bridge along the Columbia Turnpike, near the modern-day Pentagon. The ground on which the Fort stood was cut away during the construction of the Henry G. Shirley Memorial Highway, in 1942.

Fort Runyon was a timber and earthwork fort constructed by the Union Army following the occupation of northern Virginia in the American Civil War in order to defend the southern approaches to the Long Bridge as part of the defenses of Washington, D.C. during that war. The Columbia Turnpike and Alexandria and Loudon Railroad ran through the pentagonal structure, which controlled access to Washington via the Long Bridge. With a perimeter of almost 1,500 yards (1,400 m), and due to its unusual shape it was approximately the same size, shape, and in almost the same location as the Pentagon, built 80 years later.Runyon was built immediately after the entry of Union forces into Virginia on May 24, 1861, on the land of James Roach, a Washington building contractor. Fort Runyon was the largest fort in the ring of defenses that protected Washington during the Civil War and was named after Brigadier General Theodore Runyon, commander of the Fourth Division of the Army of Northeastern Virginia during the First Battle of Bull Run. Union soldiers garrisoned the fort until its dismantling following the end of the Civil War in 1865. Today, no trace of the fort remains on the site, though a historical marker has been constructed by the Arlington Historical Society.

The Pentagon Memorial, located just southwest of The Pentagon in Arlington County, Virginia, is a permanent outdoor memorial to the 184 people who died as victims in the building and on American Airlines Flight 77 during the September 11 attacks.Designed by Julie Beckman and Keith Kaseman of the architectural firm of Kaseman Beckman Advanced Strategies with engineers Buro Happold, the memorial opened on September 11, 2008, seven years after the attack.

American Airlines Flight 77 was a scheduled American Airlines domestic transcontinental passenger flight from Washington Dulles International Airport in Dulles, Virginia, to Los Angeles International Airport in Los Angeles, California. The Boeing 757-223 aircraft serving the flight was hijacked by five Saudi men affiliated with al-Qaeda on the morning of September 11, 2001, as part of the September 11 attacks. They deliberately crashed the plane into the Pentagon in Arlington County, Virginia, near Washington, D.C., killing all 64 aboard (including six crew and themselves) and another 125 in the building. Less than 35 minutes into the flight, the hijackers stormed the cockpit and forced the passengers, crew, and pilots to the rear of the aircraft. Hani Hanjour, one of the hijackers who was trained as a pilot, assumed control of the flight. Unknown to the hijackers, passengers aboard made telephone calls to friends and family and relayed information on the hijacking. The hijackers crashed the aircraft into the western side of the Pentagon at 09:37 AM ET. Many people witnessed the crash, and news sources began reporting on the incident within minutes. The impact severely damaged an area of the Pentagon and caused a large fire that took several days to extinguish. A portion of the building collapsed. The damaged sections of the Pentagon were rebuilt in 2002, with occupants moving back into the completed areas that August. The 184 victims of the attack are memorialized in the Pentagon Memorial adjacent to the crash site. The 1.93-acre (7,800 m2) park contains a bench for each of the victims, arranged according to their year of birth, ranging from 1930 to 1998.

Pentagon Transit Center is a split platform station on the Washington Metro located adjacent to The Pentagon in Arlington, Virginia. The station was opened on July 1, 1977, and is operated by the Washington Metropolitan Area Transit Authority. Providing service for both the Blue and Yellow Lines, the station is where the two lines diverge and thus acts as a transfer point. Northbound, the Blue Line continues through Virginia and the Yellow Line crosses the Potomac River into the District of Columbia. The station opened on July 1, 1977 with the completion of 11.8 miles (19.0 km) of rail between National Airport and RFK Stadium.

The Space Development Agency (SDA) is a directorate of the United States Department of Defense's office of the under secretary of defense for research and engineering (OUSD (R&E)) which supports space development in the interests of U.S. national security. By design, the functions for acquisition and sustainment (A&S) are the responsibility of another under secretary of defense; this separation of function decouples the technology development of a working prototype system, even the systems as complicated as those taken on by the SDA, from overcomplication induced by the processes of the DoD. The SDA was created in 2019 to implement the National Defense Space Architecture (NDSA). The SDA plans to transfer to the United States Space Force around October 2022, although details are still uncertain.
