W: Good evening, ladies and gentlemen. Joining me right now is Matt Cornelius, who was in the north tower of the World Trade Center that was attacked by hijacked commercial airliners. Matt, what happened?
M:[22]I had just arrived at work, probably about 8:40 a. m. I was getting ready to start the day when all of a sudden, we heard this tremendous crash. And then the floor seemed to wave.
W: You were not aware at all what could have caused this?
M: We had no idea. Obviously we know something had struck the building.
W: And your immediate instinct, I suppose, was to get out of the building.
M: Yeah. Everybody basically started running for the stairways.
W: How long did it take you to get out of the building?
M: About 45 minutes.
W: How could it have taken so long?
M: We moved very quickly. Probably 15 minutes to the 40th floor. And then after that we got held up. There were fire fighters coming up the stairs, police officers. And there was a man in a wheelchair, so we had to hold for him.
W: At what point did you become aware of what had truly happened?
M:[24]Actually, when we came out of the building, I looked back. And I saw that the second tower was on fire. And that’s when it hit me that this was truly a tragic accident.
W: What’s going through your head now?
M: I’m so thankful to be alive. My heart goes out to those who don’t know about their loved ones or have lost loved ones.
W: Matt, we appreciate you sharing your thoughts with us on this incredibly tragic day in American history.
