George W. Bush Describes the Iconic Moment He Learned About 9/11

It's an iconic image. And now, we get to know more about how former President George W. Bush learned about the tragic events of 9/11.

Bush recently recounted his memories of the day that changed his presidency in a new interview with National Geographic, set to air during a week of Sept. 11-themed shows commemorating the 10-year anniversary of the attacks.

In a clip from the interview, Bush describes the first moments when he learned of the attacks while visiting a Florida elementary school. Just before walking into the classroom, he was informed that a plane had crashed into the World Trade Center.

"I had been notified that a plane had hit the World Trade Center. At first I thought it was a light aircraft, and my reaction was man, either the weather was bad or something extraordinary happened to the pilot," Bush says. "I then informed some of my staff members to provide help to New York City, whatever help they needed to take care of this incident, and then walked into the classroom."

"The classroom was full of kids who were reading and in the back of the classroom there's the full press corps and staffers and some adults and I'm been intently listening to the lesson and I felt a presence behind me. And Andy Card's Massachusetts accent was whispering in my ear, a second plane has hit the second tower. America is under the attack."
