And for the first time, some of the children of the passengers are coming together, speaking with Lester about the lessons of Flight 93.

Here is a preview of Lester’s report:

Their names are etched in white marble, one panel for each. Forty ordinary men and women who decided to do the extraordinary when it counted most. Sacrificing themselves so that others might live in the harrowing days right after the crash, we spoke to family members still reeling from final calls home.
