The initial report on the radio was so strange it was hard to comprehend. A plane had struck the north tower of the World Trade Center in New York City. How could this happen? It was 7:46 a.m., Missouri time, and many of us were on the way to work as the news broke. Seventeen minutes later, a second plane struck the south tower. This was no accident. America was under attack.

Barely a half hour passed before a third plane crashed, this one striking the Pentagon. By then, people all across America were glued to their televisions. We watched in horror as the south tower of the World Trade Center collapsed in a cloud of dust that engulfed the city. Our thoughts immediately went to all the people frantically trying to escape the building, and to the first responders who bravely rushed toward the towers.
