9/11 remembrance ceremonies honor victims on 17th anniversary of attacks

It will be a day forever etched in the collective minds of the nation, when a quiet September morning was shattered after hijackers took control of four planes, crashing them into New York’s World Trade Center towers; the Pentagon in Arlington County, Virginia; and a field in Shanksville, Pennsylvania.

Seventeen years later, thousands will take a moment to remember the 3,000 people who lost their lives in the Sept. 11, 2001, terrorist attacks.

Here are some ways people are paying tribute across the country:

New York

The National September 11 Memorial and Museum is hosting the annual ceremony in remembrance of the victims of the 2001 and 1993 World Trade Center attacks. Starting at 8:39 a.m., family members of those who died started reading the victims' names at the World Trade Center's Memorial Plaza. There were six pauses during the readings to mark when each plane struck the towers, when each tower collapsed, when the plane hit the Pentagon, and when Flight 93 crashed in Pennsylvania, according to WABC.
