Washington Dulles International Airport (IATA: IAD, ICAO: KIAD, FAA LID: IAD), typically referred to as Dulles International Airport, Dulles Airport, Washington Dulles or simply Dulles ( DUL-iss), is an international airport in the Eastern United States, located in Loudoun County and Fairfax County in Virginia, 26 miles (42 km) west of Downtown Washington, D.C. Opened in 1962, it is named after John Foster Dulles (1888–1959), the 52nd U.S. Secretary of State who served under President Dwight D. Eisenhower. The Dulles main terminal is a well-known landmark designed by Eero Saarinen, who also designed the famous TWA terminal (now the TWA hotel) at New York's JFK airport. Operated by the Metropolitan Washington Airports Authority, Washington Dulles Airport occupies 13,000 acres (20.3 sq mi; 52.6 km2) straddling the Loudoun–Fairfax line. Most of the airport is in the unincorporated community of Dulles in Loudoun County, with a small portion in the unincorporated community of Chantilly in Fairfax County. Dulles is one of the three major airports in the larger Baltimore–Washington metropolitan area, the others being Reagan National Airport and Baltimore/Washington International Airport, and by land size and amount of facilities is the largest of the three. Dulles is considered the region's international air hub, with dozens of nonstop international flights. Dulles has the most international passenger traffic of any airport in the Mid-Atlantic outside the New York metropolitan area, including approximately 90% of the international passenger traffic in the Baltimore–Washington region. It had more than 20 million passenger enplanements every year from 2004 to 2019, with 24 million enplanements in 2019. On a typical day, more than 60,000 passengers pass through Dulles to and from more than 125 destinations around the world.Increased domestic travel from Reagan National Airport has eroded some of Dulles's domestic routes. Dulles overtook Reagan in total enplanements in 2019. However, in 2018, Dulles Airport surpassed Ronald Reagan Washington National Airport (DCA) in yearly passenger boardings after having fewer passengers since 2015. Furthermore, it still ranks behind Baltimore/Washington International Thurgood Marshall Airport (BWI) in total annual passenger boardings.Dulles is a hub for United Airlines and is frequently used by airlines which United has codeshare agreements with, mostly composed of Star Alliance members like Turkish Airlines and Lufthansa.

American Airlines Flight 444 was a scheduled American Airlines flight from Chicago to Washington, D.C.'s National Airport. On November 15, 1979, the Boeing 727 serving the flight was attacked by "the Unabomber", Ted Kaczynski, who sent the bomb in the mail and set it to detonate at a certain altitude. The bomb partially denotated in the cargo hold and caused "a sucking explosion and a loss of pressure," which was then followed by large quantities of smoke filling the passenger cabin, forcing the pilots to make an emergency landing at Dulles International Airport. Twelve passengers had to be treated afterward for smoke inhalation.

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.

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.
