The United States marked the 25th anniversary of the September 11, 2001 attacks with memorial events, including in New York City, honoring the nearly 3,000 people killed. Coverage included personal stories such as Lori Guadagno, who lost her brother on United Flight 93 and finds peace visiting the crash site in Pennsylvania, Manhattan's Trinity Church unveiling a new pipe organ to replace one damaged in the attacks, and Gen Z Americans reflecting on when they first learned about 9/11. The anniversary prompted widespread reflection on the attacks' lasting impact on American society, memory, and identity a quarter-century later.
