Spilling Thought: On Tuesday morning, September 11, 2001, the United States came under attack when four commercial airliners were hijacked in an act of terrorism. Two planes were flown into the World Trade Center in New York and a third into the Pentagon in Virginia. Nearly 3,000 people tragically lost their lives. Because of the actions of the 40 passengers and crew aboard the fourth plane, Flight 93, the U.S. Capitol was saved. Everyone remembers where they were and how they felt when they heard the terrible news, but for future generations lacking that emotional memory, the Flight 93 National Memorial provides a connection to the people and events that changed the course of the history. By visiting this place and hearing their stories, those who were taken will never be forgotten. Today the National Park Service, its volunteers, and its partners work to honor their sacrifice and to try to understand more fully the legacy of Flight 93 and the other events of 9/11. We will #NeverForget. To learn more about our efforts to share this important story, go to: http://on.doi.gov/1Kfm5m9 Photo from the Flight 93 National Memorial by Tami A.
