I was watching "United 93", the first movie I've seen about September 11th 2001, just a few days before the memorial of six years after this tragedy. The movie is in general well written, and for the first time in my video-watching history, I actually checked out the 'Extras' at the end of the movie. In it (the DVD version), there are many families featured, who have lost someone in that flight, and how they were involved in the making of the movie. That was, I thought, the most touching part and telling, too!
One mother, interviewed in 2005, a year before the movie was released, said something to the effect that she did not know what kind of person her daughter really was until after her death. In a way the tragedy 'opened' her eyes, but she was still grieving for what could have been, what life they could have led together. Many lives were cut short that day, and I too was reminded to count on what really matters in our brief lives. May they rest in peace.
