Smoke billowed from the sky scraper. Screams, yells and whimpers could be heard from all around. One lone man stay sat in his office, oblivious to the chaos: his sound excluding headphones silenced the outside world. A few minutes later, smoke crept into the room from underneath the door, drowning the room in fumes. The man, smelling something burning, finally looked up to see nothing but a smoky haze. He gasped. Smoke penetrated his lungs, making it difficult to breathe. He nearly fainted at the loss of air.
The man realised he needed to retreat from his office, and the tower. Clambering over to the window and after removing his headphones, he had thought of the best escape route. He clumsily, but quickly, opened the massive paned framework and thrust his head out; he could breathe more easily. On the opposite side of the door, flames engulfed the whole corridor. The blazing fire licked at the office door, begging to be let in. The man could hear the crackle of wood burning behind him, and fumbled about with his plan even quicker.
The man tugged the now dirty white shirt off his torso in a hurry, ripping off a few buttons white doing so. Forcing his t-shirt clad upper-body out the window; he waved his shirt around to get someone's attention. He waved, looking very small in the smoky clouds, but no one saw him for a long while. The flames entered the room, the whole area glowing orange. The man felt the heat on his back, bullying him to stop. But the man didn't surrender; he was desperate to survive.
Out of the window, the man could see people free-falling from levels above. He couldn't see the ground, but he was sure it was painted blood-red. Eventually, the flames reached the man, and in one last act before falling into unconsciousness from the searing pain, he propelled himself out of the building. He could unconsciously feel himself land on something fairly soft, and the faint smell of disinfectant could be detected a short while later.
The adult Phineas didn't know where he was, but years later, many people, especially his family and friends, would be celebrating his survival, along with the mourning of many people's deaths. Each year, people will visit the site of the disaster, and remember all those who died and all those who survived. They will think of all the children who lost their parents, and think of how lucky they are to have survived, or to have not been near the attacks at all.
