First major memorial to 3,000 victims of terrorists crashed passenger jets into the Pentagon, the World Trade Center and a grassy field in Pennsylvania will be dedicated on Thursday, 7 pm at the Somerset Alliance Church in Somerset after 7 years tragic loss.

Seven years is “not a long time” to build a major memorial, says Ed Linenthal, an Indiana University religious studies professor who studies commemoration.

In lower Manhattan, seven major projects at Ground Zero is underway , a tribute to the 2,750 who died tragically in the crash.

In Pennsylvania, the National Park Service is still buying land for a 2,200-acre memorial to the 40 crew members and passengers of United Flight 93 who tried to overpower four hijackers before their jet crashed.

United 93 is one of the great memorials of plane crashed in a field just outside Shanksville, Pennsylvania. A 2006 film written and directed by Paul Greengrass that chronicles events aboard United Airlines Flight 93, which was hijacked during the September 11, 2001 attacks.

Ten percent of the gross from the three-day opening weekend was promised toward a donation to create a memorial for the victims of Flight 93. The film grossed $31.4 million in the United States, and $76.2 million worldwide.
