Survivors of 9/11 say they remember gathering belongings before leaving offices and cubicles. They put on coats and called loved ones. They shut down their computers and had conversations. Even in their descent, most moved at a leisurely pace—no screaming or running. There was no need for anyone to say “Remain calm everyone,” because they weren’t freaking out. They were begging the world to return to normal by engaging in acts of normalcy.
