Welles Crowther was working on the 104th floor of the South Tower when the planes hit on September 11, 2001. The 24-year-old had a job as an equities trader, but he also volunteered as a firefighter back home. When the attack happened, he did what he was trained to do and helped people get out.
Crowther always kept a red bandana with him. His dad gave it to him when he was just six years old, and he carried it everywhere. He wore it when he played sports at Boston College and even kept it on his work desk. That day, he tied it around his face to protect himself from the smoke.
