Vaughn Allex was working the ticket counter at American Airlines at Dulles Iinternational Airport on Sept. 11, 2001, when two men arrived, late for Flight 77.

"I didn't know what I had done," Allex told StoryCorps. "I came to work and people wouldn't look at me in the eye."
Officials handed him the manifest for the flight. “I just stared at it for a second and then I looked up, I go, ‘I did it, didn't I?’ ”
Allex said people stopped talking to him, and he began to believe he was to blame for what happened on Sept. 11. He tried attending support groups but it was uncomfortable.

“I feel like in some ways I've — I really have come out of a shadow over the last 15 years,” he said, “and I'm — I'm back in the light now.”
