Look back at some of the many unforgettable images from the day America was attacked on 9/11.
The morning of Sept. 11, 2001, began as a bright, sunny early fall day. That morning, former President George Bush was reading to a group of students at Emma E. Booker Elementary School in Sarasota, Fla., when he was told that a plane had hit the World Trade Center in New York. Initially, an accident seemed the most likely explanation. But the reading event was cut abruptly short after an aide whispered to Bush that a second plane had hit the other Twin Tower.
