If you read the quotes from the phone calls placed from that flight – it is quite remarkable. Multiple folks, independently, male and female, tell their loved ones “I have to go. We’re going to do something now”. It is really quite inspirational.
I understand the backlash against the commercial schmaltz.
I have seen many comments say 9/11 pales in comparison to the atrocity of say, our actions in Iraq. Well, point me to an instance where we intentionally and successfully killed thousands of civilians, intentionally, in a single act. There is no analog, in my view.
