2025 Potomac River mid-air collision

The National Intelligence University (NIU), formerly known as the Defense Intelligence School, the Defense Intelligence College, the Joint Military Intelligence College, and the National Defense Intelligence College is a federally chartered research university in Bethesda, Maryland. NIU is the United States Intelligence Community's (IC) institution for higher learning in fields of study central to the profession of intelligence and national security. NIU awards undergraduate and graduate degrees, a graduate certificate, and prestigious research fellowships to prepare personnel for senior positions in the IC and the broader national security enterprise. Since 1963, more than 80,000 military and civilian students have attended the university. Formerly located at the Defense Intelligence Agency headquarters in Washington, D.C., NIU's primary campus is now located at Intelligence Community Campus-Bethesda (ICC-B) with four additional locations around the world. National Intelligence University's interdisciplinary programs emphasize education through scholarly and applied research designed to help U.S. intelligence officers better understand the diverse range of geopolitical, strategic, and technological threats and opportunities affecting intelligence and national security. The university is organized into two separate academic units: the College of Strategic Intelligence and the Anthony G. Oettinger School of Science and Technology Intelligence. Combined, the college and school cover a diverse and evolving range of international affairs issues and adversarial threats and capabilities, from cultural and religious conflicts to WMD proliferation, cybersecurity threats, terrorism, transnational crime, and more.Congressionally chartered and publicly funded but with admissions restricted solely to current U.S. Intelligence officers holding a Top Secret/Sensitive Compartmented Information clearance, NIU is a small, non-resident university. Admissions are highly selective, but tuition is paid by the United States Government.

Joint Base Anacostia–Bolling is a 905-acre (366 ha) military installation, located in Southeast, Washington, D.C., established on 1 October 2010 in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. The legislation ordered the consolidation of Naval Support Facility Anacostia (NSF) and Bolling Air Force Base (BAFB), which were adjoining, but separate military installations, into a single joint base, one of twelve formed in the country as a result of the law. The base hosts the Defense Intelligence Agency Headquarters amongst its other responsibilities. The only aeronautical facility at the base is a 100-by-100-foot (30 by 30 m) helipad (ICAO: KBOF).

Bolling Air Force Base or Bolling AFB was a United States Air Force base in Washington, D.C. In 2010, it was merged with Naval Support Facility Anacostia to form Joint Base Anacostia–Bolling. From its beginning, the installation has hosted elements of the Army Air Corps (predecessor to today's Air Force) and Navy aviation and support elements.

United States Coast Guard Station Washington is a United States Coast Guard station located on Joint Base Anacostia-Bolling in Washington, D.C. The station was commissioned on September 23, 2003.

The Anacostia River is a river in the Mid Atlantic region of the United States. It flows from Prince George's County in Maryland into Washington, D.C., where it joins with the Washington Channel to empty into the Potomac River at Buzzard Point. It is approximately 8.7 miles (14.0 km) long. The name "Anacostia" derives from the area's early history as Nacotchtank, a settlement of Necostan or Anacostan Native Americans on the banks of the Anacostia River. Heavy pollution in the Anacostia and weak investment and development along its banks have led to it becoming what many have called "D.C.'s forgotten river." In recent years, however, private organizations, local businesses, and the D.C., Maryland and federal governments have made joint efforts to reduce its pollution levels in order to protect the ecologically valuable Anacostia watershed.

Ronald Reagan Washington National Airport (IATA: DCA, ICAO: KDCA, FAA LID: DCA), also known as National Airport, Washington National, Reagan National Airport, DCA, Reagan, or simply National, is a national airport in Arlington, Virginia, across the Potomac River from Washington, D.C. It is the smaller of two airports operated by the Metropolitan Washington Airports Authority (MWAA) that serve the National Capital Region (NCR) around Washington (the larger airport being Washington Dulles International Airport about 25 miles (40 km) to the west in Virginia's Fairfax and Loudoun counties). The airport is 5 miles (8.0 km) from downtown Washington, D.C., and the city is visible from the airport. The airport's original name was Washington National Airport. Congress adopted the present name to honor President Ronald Reagan in 1998; however, locals are often split on what to call the airport. MWAA operates the airport with close oversight by the federal government due to its proximity to the national capital. Flights into and out of the airport are generally not allowed to exceed 1,250 statute miles (2,010 km) in any direction nonstop, in an effort to send coast-to-coast and overseas traffic to Washington Dulles International Airport, though there are 40 slot exemptions to this rule. Planes are required to take unusually complicated paths to avoid restricted and prohibited airspace above sensitive landmarks, government buildings, and military installations in and around Washington, D.C., and to comply with some of the tightest noise restrictions in the country.The airport's small size constrains its capacity, but Reagan National currently serves 91 nonstop destinations. Reagan is a hub for American Airlines. The airport has no United States immigration and customs facilities; the only scheduled international flights at the airport are those from airports with U.S. Customs and Border Protection preclearance facilities, which generally encompasses flights from major airports in Canada and from some destinations in the Caribbean. Other international passenger flights to the Washington, D.C. area use Washington Dulles International Airport or Baltimore–Washington International Thurgood Marshall Airport. Prior to the COVID-19 pandemic, there were five scheduled international routes to cities in Canada, the Bahamas, and Bermuda; Bermuda and Ottawa have yet to be resumed as of early 2022.The airport served 23.5 million passengers in 2018. In 2019, DCA served 23,945,527 passengers, an increase of 1.8% over 2018, and a new passenger record for the airport.

The Defense Intelligence Agency Headquarters (DIA HQ) is the main operating center of the Defense Intelligence Agency. It is located on the premises of Joint Base Anacostia–Bolling in Washington, DC.

Naval Support Facility (NSF) Anacostia was a United States Naval Base in Washington, D.C., close to where the Anacostia River joins the Potomac River. On 1 October 2010 the base was conjoined with the adjacent Bolling Air Force Base to form the Joint Base Anacostia–Bolling in accordance with congressional legislation implementing the recommendations of the 2005 Base Realignment and Closure Commission. NSF Anacostia fell under the command of Naval Support Activity Washington.

Hains Point is located at the southern tip of East Potomac Park between the main branch of the Potomac River and the Washington Channel in southwest Washington, D.C. The land on which the park is located is sometimes described as a peninsula but is actually an island: the Washington Channel connects with the Tidal Basin north of the park and the Jefferson Memorial. The island is artificial: it was built up from Potomac dredging material from 1880 to 1892.

The Editors Building, also known as the Kiplinger Building, is a historic office building located in Washington, D.C.. The ten-story structure was built between 1949 and 1950, and was originally constructed as the headquarters of the Kiplinger Washington Editors, a financial advice publishing firm based in the city. It was built by the D.C.-based architect Leon Chatelain Jr. and designed in the Stripped Classical style, featuring a mostly unornamented façade with significant vertical massing. W.M. Kiplinger, the business's founder, was an avid collector of D.C.-area memorabilia, and he displayed his 7,000-piece collection in the Editors Building's lobby, hallways, and offices. The publishing agency kept its headquarters located in the building until selling it in 2011. The new owners kept the exterior intact while gutting the interior, and in 2013 it reopened as a Hampton Inn hotel. The building was listed on the National Register of Historic Places in 2015.

Shepherd Parkway is part of the Civil War Defenses of Washington. It includes two forts (Forts Greble and Carroll), of which some remains still exist. The parkway runs along the high ground opposite the Anacostia Freeway (Interstate 295) from Joint Base Anacostia–Bolling in the District of Columbia. Shepherd Parkway is bordered on the north by St. Elizabeths Campus and the District of Columbia neighborhoods of Congress Heights and Bellevue and on the south (near Oxon Run) by Bald Eagle Hill.

A 9-foot bronze statue of Ronald Reagan was installed in Arlington, Virginia, in 2011.
