Saturday in Somerset County, the Flight 93 National Memorial will be officially dedicated and opened to the public. The ceremony will mark the completion of a 10-year effort to honor the 40 passengers and crew members who perished when the plane crashed in a rural field in Stonycreek Township. Tim Lambert, the news director at WITF-FM in Harrisburg, owned land that was considered an essential part of the crash site -- land that is now a part of the memorial. He's spent more time walking those grounds than most and in this exclusive story, revisits the property with a Flight 93 family member.
