TULSA, Oklahoma -- The images of 9/11 are forever etched into our minds. Tulsan Tiana Daugherty is a pilot for United Airlines.
She was friends with Captain Jason Dahl, who was flying Flight 93 when it was hijacked and crashed in Pennsylvania that fateful day.
Daugherty says the terrorist attacks not only changed the country, but her entire world.
"I still get choked up, it's almost obsessive to watch some of the stuff that comes on TV," she said. "The drop of a hat, the tears spring to your eyes. Get you thinking about stuff, if it hits you just right."
Daugherty wasn't scheduled to fly on 9/11, but the day after.
