“If we learn nothing else from this tragedy, we learn that life is short and there is no time for hate.” — Sandy Dahl, wife of Flight 93 pilot Jason Dahl Twenty-one years ago, shortly after the tragic events at the World Trade Center in New York and the Pentagon in Virginia that killed nearly 3000 people, the 40 passengers and crew members on Flight 93 fought a battle in the sky over Pennsylvania. Today, Flight 93 National Memorial honors this incredible sacrifice. We will never forget.
