Final calls from a loved wife

He heard a simple, heartbreaking message from his wife, who was trapped on the 101st floor of the North Tower.

"Sean, it's me. I just wanted to let you know I love you and I'm stuck in this building in New York. A plane hit the building, or a bomb went off. We don't know, but there's a lot of smoke and we just wanted you to know that I love you always."
