Loudoun Gateway station

On January 29, 2011, Bethany Anne Decker (née Littlejohn; born May 13, 1989) left her husband's parents' home in Maryland and returned to her apartment in Ashburn, Virginia. Her boyfriend, Ronald Roldan, says he saw her there later that day. She has not been seen since. While Decker did not show up at her job or classes she took at nearby George Mason University, her absence was not noted for another three weeks, since messages to her friends purportedly from her continued to be posted on her Facebook account. After her family noted her absence otherwise, they found her car parked near her apartment. Apart from the Facebook posts, there had been no other evidence she had done anything since the day she was last seen. They reported her missing to Loudoun County Sheriff's Office. Decker was five months pregnant at the time of her disappearance. Extensive searches have found no trace of her or the child she might have given birth to. Roldan, who had a criminal record prior to the disappearance, was arrested in North Carolina in 2015 and charged with the attempted murder of another girlfriend after he shot her during an incident in 2014; he has not said anything about the Decker case. After she recovered, the victim claimed on the Dr. Phil show that he had made statements to her that might implicate him in Decker's disappearance. Roldan pled guilty to two lesser charges in 2016; after he served his sentence, he was expected to be deported to his native Bolivia. Instead, he was charged with Decker's abduction upon his release in 2020 and returned to Loudoun County. The incident has been the subject of a segment of the Investigation Discovery channel series Disappeared.

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.

Broad Run High School is a public secondary school in Ashburn, an unincorporated area in Loudoun County, Virginia, United States. Broad Run is part of the Loudoun County Public Schools system (LCPS). It was ranked as the #1 Best Public High School in Loudoun County and the #9 Best Public High School in Virginia by U.S. News in 2020. Originally a rural school serving all of eastern Loudoun County, the growth of the county's population beginning in the mid-1990s has resulted in systematic reduction of Broad Run's attendance area as it spun off eight of the district's high schools from within its original boundaries. Initial surroundings of farm fields have been replaced by housing tracts and the school now possesses one of the most culturally diverse student populations in the region. Broad Run High School is also located in one of the most affluent zip codes and counties in the country with recorded median income of more than $100,000 per household. After a period of high construction in the early 2000s, the number of high schools in the area stayed the same until Briar Woods and Freedom High School opened in 2005, John Champe High school in 2012, Rock Ridge High School in 2014, and Riverside High School completed construction in 2015.In 1969, Loudoun County opened its third public high school amidst corn fields in Ashburn to accommodate the growing student populations resulting from new housing developments in the unincorporated communities in the eastern half of the county. Since then, the county population has increased nearly sevenfold (most of it in the east), straining education budgets, infrastructure, and local politics. For Ashburn, this has resulted in constantly shifting attendance boundaries as new schools are constantly being opened, at all levels, elementary, middle, and high. The area's student demographics have significantly changed as well: Loudoun County's residents are now the country's most affluent (per capita), and its ethnic composition continues to diversify as foreign immigration into Northern Virginia increases. Before the 2011–2012 school year, additional lockers were installed due to increases in the school's population.
