Years ago, you probably read this long but beautifully written story in The New Yorker about the heroic Rick Rescorla. I believe that it is worth rereading today.
All The Heroes Are Dead
A love Story
By James B. Stewart
From Wikipedia 
Rescorla was supposed to be on vacation on September 11,  2001, in preparation for his stepdaughter's upcoming wedding in Tuscany. But as well as covering a shift  so one of his deputies could go on vacation, he was also scheduled to attend a  lunchtime meeting to discuss the lawsuit Morgan Stanley was filing against the  Port Authority about the security lapses that led to the 1993 attack.
At 8:46 a.m., American Airlines Flight 11 struck  World Trade Center Tower 1 (see September 11, 2001 attacks).  Rescorla, following his evacuation plans, ignored building officials' advice to  stay put and began the orderly evacuation of Morgan Stanley's 2,700 employees on  twenty floors of World Trade Center Tower 2, and 1,000 employees in WTC 5.  Rescorla reminded everyone to "...be proud to be an American ...everyone will be  talking about you tomorrow", and sang God Bless America and other military and  Cornish songs over his  bullhorn to help evacuees stay calm as they left the building, including an  adaptation of the song Men  of Harlech:
Men of Cornwall stop your dreaming;
Can't you see their spearpoints gleaming?
See their warriors' pennants streaming
To this battlefield.
Men of Cornwall stand ye steady;
It cannot be ever said ye
for the battle were not ready;
Stand and never yield!
Rescorla had most of Morgan Stanley’s 2700 employees as well as people  working on other floors of WTC 2 safely out of the buildings by the time United Airlines Flight 175 hit WTC 2  at 9:03 a.m. After having led many of his fellow employees to safety, Rescorla  returned to the building to rescue others still inside. When one of his  colleagues told him he too had to evacuate the World Trade Center, Rescorla  replied,
"As soon as I make sure everyone else is out".
How ironic that the man who predicted 9/11 would end up perishing in the tragedy
