Today marks the eighth anniversary of the Sept. 11, 2001, terrorist attacks.
Ceremonies were scheduled this morning to honor the 2,752 people who perished in the attack on the World Trade Center in New York, the 33 passengers and seven crewmembers who died when their hijacked plane crashed in a Pennsylvania field, and the 184 government workers and plane passengers who died at the Pentagon outside Washington, D.C.
In April, President Obama signed legislation declaring Sept. 11 a National Day of Service and Remembrance.
