Here's the story about a regular guy, Welles Crowther, who went up and down the WTC stairs repeatedly leading and even carrying out strangers who survived the 9/11 attacks.

https://www.youtube.com/watch?v=WC36eqR1nxgOn September 11, 2001, minutes after United Airlines Flight 175 struck the South Tower between floors 77 and 85 at 9:03a.m., Crowther called his mother from his office at 9:12 a.m., leaving the message, "Mom, this is Welles. I wanted you to know that I'm OK." Crowther made his way to the 78th floor sky lobby, where he encountered a group of survivors, including a badly burned Lin Young, who worked on the 86th floor in New York's Department of Taxation and Finance. Young had been one of about 200 people waiting at a bank of elevators to evacuate when the plane hit the tower and was one of the few survivors. Crowther, carrying a young woman on his back, directed them to the one working stairway. The survivors followed him 17 floors down, where he dropped off the woman he was carrying before heading back upstairs to assist others. By the time he returned to the 78th floor, he had a bandana around his nose and mouth to protect him from smoke and haze. He found another group of survivors, which included AON Corp. employee Judy Wein, who worked on the 103rd floor and was in pain from a broken arm, cracked ribs and a punctured lung. According to Wein, Crowther assisted in putting out fires and administering first aid. He then announced to that group, "Everyone who can stand, stand now. If you can help others, do so." He directed this group downstairs as well. As occupants of the Tower headed for the street, Crowther returned up the stairs to help others. He was last seen doing so with members of the FDNY before the South Tower collapsed at 9:59 a.m.
Crowther's body was found in March 2002, alongside several firefighters and emergency workers bunched in a suspected command post in the South Tower lobby. The New York medical examiner's office said his body was found intact, with no signs of burns, and that authorities speculated that he was aiding the rescue effort as a civilian usher when the building collapsed. Crowther's family was unaware of the details of his activities between his last phone call to his mother and his death, until Allison Crowther read Judy Wein's firsthand account in The New York Times of being saved by a man in a red bandana, which led to Allison meeting with the people Welles had saved, including Wein and Young. They confirmed from photographs the identity of the man who aided them. According to survivor accounts, Crowther saved as many as 18 people following the attacks.Welles Crowther, 5/17/77-9/11/01
