Passage: We were under the impression – he looked like he was going down, but we didn't hear any mechanical difficulty. We couldn't figure out why an American Airlines plane would be so low in downtown Manhattan. We sort of expected him to veer off and go into the Hudson. But he just rose a little bit, his altitude, leveled off, and he was headed straight for the Trade Center. So just before he got to the Trade Center, it seemed as though he gained power. We were just watching this airplane on target for the World Trade Center. All of a sudden, boom! He disappears into the Trade Center.

Question: What location was the airplane headed for?
World Trade Center
