America remembers the victims of the Sept. 11th terror attacks with ceremonies across the country Monday.
Commemorations in New York begin at 8:46 a.m. ET with a citywide moment of silence marking the moment the first plane hit the World Trade Center's North Tower. The second plane hit the South Tower at 9:03 a.m. ET.
President Trump will lead a moment of silence at the Pentagon at 9:37 a.m. ET, the moment American Airlines Flight 77 struck the building.
The fourth and final plane went down in Shanksville, Pa., at 10:03 a.m. ET, but the Flight 93 National Memorial ceremony starts earlier, at 9:30 a.m. ET.
The names of each of the nearly 3,000 people killed by the attacks will be read aloud Monday at the 9/11 Memorial and Museum.
USA TODAY will provide live coverage of the ceremonies in New York and at the Pentagon in the player above.
