Dulles International Airport

Willard (also known as Willard Crossroads) was an unincorporated community located in what is now a part of Washington Dulles International Airport in the U.S. state of Virginia. The village was named after Joseph Edward Willard, a delegate to the Virginia General Assembly from 1893 to 1901, then Lieutenant Governor of Virginia. Although Willard lived in Loudoun County, he represented Fairfax County, because the village was only 1,500 feet (460 meters) from the county border. Willard owned a 50-acre (20-hectare) estate in Fairfax. His father was Joseph Clapp Willard, the owner of the famed Willard Hotel in Washington, D.C. Willard was at the intersection of Willard Road (now Stonecroft Boulevard) and Sterling Road (now Horsepen Road), surrounded by extensive farmland, housing, schools, places of worship, the Willard store (until 1907), and Blue Ridge Airfield (1938–1951). Willard stood west of Floris, north of Pleasant Valley, and south of Farmwell (now Ashburn). Willard was regarded as a crossroads and a distinctive community until construction of Washington Dulles International Airport began in 1958. Approximately 26 square miles (67 square kilometers) of Virginia land from Willard, Chantilly, Pleasant Valley, Sterling, and Ashburn was bought for construction. By the airport's completion, all remains of civilization before 1958 on this land had virtually disappeared, except a stretch of Willard Rd (used as a service road), and three storage outbuildings between Runways 1C/19C and 1R/19L.

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.

Dulles () is an unincorporated area in Loudoun County, Virginia, United States, and is part of the Washington metropolitan area. The headquarters of Northrop Grumman Innovation Systems and ODIN Technologies, as well as the former headquarters of MCI Inc. and AOL are located in Dulles. The National Weather Service Baltimore/Washington forecast office and the National Weather Service's Sterling Field Support Center are also both in Dulles.

The Dulles International Airport Main Terminal is located in Loudoun and Fairfax counties in Dulles, Virginia, United States. The original structure, 600 feet (180 m) long and 150 feet (46 m) wide, was designed by Eero Saarinen and completed in 1962 as the first terminal at Dulles International Airport. Annexes to the west and east were completed in 1996 as part of a renovation designed by Skidmore, Owings & Merrill, bringing its total length to 1,240 feet (380 m). The terminal is operated by the Metropolitan Washington Airports Authority, which operates Dulles Airport as a whole. The terminal's design is a suspended structure with roof panels of precast concrete suspended between cables which span the width of the building. The Main Terminal's design includes parallel slanted colonnades on the terminal's north and south facades, interspersed with glass walls. The landside facade to the north is taller than the airside facade to the south; a concave roof supported by cables connects the two facades, descending at the center. A concourse and control tower extend south toward the airport's apron. The interior was originally divided into two levels: an upper story for departing passengers and a lower story for arriving passengers. Saarinen's original design included mobile lounges that ferried passengers directly to planes, reducing the need for long walks or taxiing while increasing the airport's operational flexibility. The modern terminal includes four Z gates, where aircraft could unload passengers directly. In addition, two basements contain security screening facilities and an AeroTrain people-mover station. The 1950 Washington Airport Act provided funding for Dulles Airport, land for which was acquired in January 1958. Saarinen was selected that May to design the terminal, construction of which began in early 1960. After several delays, the terminal was dedicated on November 17, 1962, along with the rest of the airport. Initially, Dulles Airport saw lower-than-expected usage, but increased patronage prompted the airport's original operator, the Federal Aviation Administration (FAA), to contemplate an expansion in the early 1970s. Hellmuth, Obata & Kassabaum (HOK) built two small annexes to the south in 1978, and further expansions and additional terminals were contemplated in the 1980s following increases in patronage. SOM designed annexes to the west and east, which began construction in October 1993 and were dedicated on September 6, 1996. Additional expansions took place in the 2000s, including the Z gates and the basements. The structure was widely acclaimed when it was completed, particularly regarding its shape, and Saarinen reportedly considered it his best work. The terminal has also received numerous awards, including the American Institute of Architects' Twenty-five Year Award, and other terminal buildings have been compared with it. Though the Main Terminal was nominated for inclusion on the National Register of Historic Places in 1978, it was never added due to objections from the FAA.

Dulles International Airport is a planned Washington Metro station at Washington Dulles International Airport in Loudoun County, Virginia, U.S., on the Silver Line.

The station was originally planned to be underground, but was built as an above-ground station next to daily parking garage one.

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.
