PITTSBURGH (AP) — A project to compile oral histories of those connected to the crash of hijacked United Airlines Flight 93 will continue for at least the next three years due to a $225,000 grant from The Heinz Endowments.The Pittsburgh-based charity has also helped fund the design and construction of the Flight 93 National Memorial about 60 miles southeast of the city, where the airliner crashed killing all 40 passengers and crew aboard during the Sept. 11, 2001 terrorist attacks.The oral history project began in 2005. More than 700 interviews with family, friends and colleagues of the passengers and crew, as well as investigators, first responders and others with a connection to the site have been collected and archived. That information is also being used to prepare brochures, exhibits and educational materials for the memorial and its website.
