On this, the eighth anniversary of the September 11 terrorist attacks, President Barack Obama will deliver a speech, while many across the nation will be honoring those who lost their lives on September 11, 2001.

The official New York City observance of the anniversary of 9/11 will take place at the World Trade Center site on the morning of Friday, September 11th, 2009. In honor of the new federal designation of September 11th as a National Day of Service and Remembrance, family members will read the names of all 2,751 victims aloud. Each family member will be paired with a volunteer from the five boroughs who will represent the spirit of compassion and giving that unified New York City in the weeks and months following the tragedy.

As always, four moments of silence will be observed to commemorate the times when each plane hit and each tower fell. At sunset, the famous "Tribute in Light" will return to the skies above New York City for the night.

As with previous years, there will be a memorial service held at the Flight 93 National Memorial. The formal commemorative service will take place on Friday morning, September 11, 2009, a short distance from the crash site on Skyline Road near Shanksville, Pennsylvania (please see specific directions to the site). The service begins at 9:45 AM.

There is also going to be a memorial service held at the Pentagon in Arlington, Virginia. Wreath laying will take place at 9:40 a.m. The memorial commemorates the 184 lives lost in the Pentagon and on American Airlines Flight 77 during the terrorist attacks. The Pentagon Memorial is free and open to the public 24 hours a day. Feel free to visit any time.
