The United States observed the 25th anniversary of the September 11, 2001, terrorist attacks with multiple commemorations and renewed efforts to engage younger Americans in understanding the tragedy. President Donald Trump paid respects at the Pentagon, the site of one of the attacks, while Vice President J.D. Vance and four former presidents—Joe Biden, Barack Obama, Bill Clinton, and George W. Bush—attended events at the Ground Zero memorial in Lower Manhattan on September 11, 2026 [1, 2, 3].

On that day in 2001, 19 Al-Qaeda hijackers took control of four planes. Two planes crashed into the North and South Towers of the World Trade Center, causing their collapse. A third plane hit the Pentagon. Passengers on the fourth plane fought back, leading it to crash in a Pennsylvania field rather than its likely intended target, either the Capitol or White House [2, 3]. The attacks killed 2,977 people, mostly in New York City. More than 9,400 have died since from illnesses related to 9/11 exposure, according to government health records [1, 2, 3].

Beth Hillman, 59, president of the 9/11 Memorial & Museum and a US Air Force veteran, said many in her generation still remember exactly where they were on that day. She noted, however, that about 100 million Americans either were not born or were too young to remember 9/11 firsthand [1, 2, 3]. Hillman said, "Many in my generation remember exactly where we were on that horrific day" [1].

The museum is focusing on outreach and education to ensure the story and lessons of 9/11 are passed on. Volunteers like Logan Miller, who lost family members, share personal stories to help younger visitors grasp the attack’s magnitude [1, 2, 3]. Miller said it remains easier for those who experienced the era to appreciate the disaster compared to younger generations [2].

Younger visitors tend to ask more questions about the attacks than older ones. Ignacio Gaete, a 22-year-old visitor from Chile, said although he was not born in 2001, visiting the memorial was important. He said, "I think it can transcend generations" [1, 2, 3].

Looking ahead, Khalid Sheikh Mohammed, a key planner detained for 20 years, is scheduled for trial in June 2028 at Guantanamo Bay military base for his role in the attacks [2, 3].
