A moment of silence falls across the nation as bells ring out in New York City marking the moment 17 years years ago, at 8:46 in the morning, when the first tower of the World Trade Center was attacked on September 11th.
The names of every person killed that day read aloud; nearly 3,000 people lost and remembered.
Another 184 names are read at the Pentagon where, just after sunrise, a flag is unfurled down the side of the building, covering the exact spot where a plane hit that day.
In Shanksville, the president and first lady were there to honor the 40 passengers and crew members of Flight 93 who sacrificed their lives to bring down the hijacked plane.
As the reading of names continues in New York, taking hours to get through the number of lives stolen nearly two decades ago.
