This was an interesting article about the last person to survive the World Trade Center attacks on 9/11/01. Ron DiFrancisco, who was 37 at the time, ran down over 80 flights of stairs to get to the ground floor. As he ran out the door, the 2nd tower collapsed right next to him. The last thing he remembers seeing was a giant fireball. He woke up days later in a New York City hospital...
He reached a landing in the impact zone and joined others lying on the floor, gasping for air. But a voice told him to get up and keep going. He ran down the stairs, covering his face with his forearms as he fought through the flames.
Finally he reached the ground floor, where a security guard directed him to a different exit. As he reached it, he heard a giant roar as the building began to collapse. He turned and saw a fireball heading right at him. Days later, he woke up in the hospital with lacerations on his head, burns all over his body, and a broken bone in his back.
