Overview
- On Sept. 11, 2001, 19 al‑Qaeda hijackers flew four planes into U.S. targets, killing about 2,977 people and destroying the Twin Towers in New York.
- President Trump will speak at the Pentagon rather than at Ground Zero, a move that has focused attention on keeping public commemorations nonpartisan while past presidents and the vice president plan to attend the New York ceremony.
- Federal World Trade Center Health Program data released for the anniversary show more than 9,400 additional deaths tied to 9/11‑related illnesses and roughly 85,000 medical certifications for responders and survivors.
- Museums and memorial groups are expanding education and outreach to younger Americans who did not live through 2001, using volunteers, new exhibits and school programming to close a widening generational gap in lived memory.
- The attacks reshaped U.S. institutions and policy with the creation of DHS, TSA, ICE and the Patriot Act, prompted long wars with large casualty estimates and left legal threads active, including a Khalid Sheikh Mohammed trial set for June 2028 at Guantanamo.
