(Stony Creek Township) -- At the newly dedicated Flight 93 National Memorial, families of the 40 passengers and crew who died on the hijacked jetliner laid to rest three caskets containing unidentified remains of their loved ones. Somerset County Coroner Wallace Miller says all the family members long ago received the identified remains of their loved ones. Miller says the burial of the unidentified remains is an event that belongs to the families of the Flight 93 heroes alone. "It is a private moment, and for the last two days, they've opened up and allowed the public in to everything, but I think that we owe it to them on this final day to let this be a private affair," he says. Miller says families of the 40 people who died on Flight 93 decided to bury the unidentified remains on the jetliner’s crash site once the plans were finalized for the National Memorial in the same spot. The men and women who died on Flight 93--called heroes, not victims--broke into the cockpit of their plane to wrest control from four terrorist hijackers aboard on September 11th, 2001.
