Flight 93 Memorial Opens

It has been 10 years since the terror attacks of 9-11, and the American people are marking that anniversary in many ways.

The National Park Service is unveiling the permanent Flight 93 National Memorial in Somerset County, Pa., at the site where the jetliner crashed, taking the lives of 40 passengers and crew.

The memorial blends with the crash site and the surrounding landscape to showcase the serenity of the area while acknowledging the raw violence of what happened there.
