When the tower collapsed, only 13 Morgan Stanley colleagues--including Rescorla and four of his security officers--were inside.

The six who died included Rescorla himself, who went back in to get more people out.

Rescorla felt it was foolish to rely on first responders to save his employees.

Rescorla implicitly understood that he could turn office workers into survivors.

The radicalism of Rescorla's drills cannot be overstated.

Rescorla had once led soldiers through the night in the Vietcong-controlled Central Highlands of Vietnam.

"Stop, " Rescorla ordered through the bullhorn.

Afterward, Rescorla had the credibility he needed.

Now, in the crowded stairwell, Rescorla sang into the bullhorn.

After the first few drills, Rescorla chastised employees for moving too slowly in the stairwell.

After the 1988 bombing of Pan Am Flight 103 over Lockerbie, Scotland, Rescorla worried about a terrorist attack on the Trade Center.

Rescorla learned many of the tricks of survival in the military.
