This final report is only a summary of what we have done, citing only a fraction of the sources we have consulted. But in an event of this scale, touching so many issues and organizations, we are conscious of our limits. We have not interviewed every knowledgeable person or found every relevant piece of paper. New information inevitably will come to light. We present this report as a foundation for a better understanding of a landmark in the history of our nation. We have listened to scores of overwhelming personal tragedies and astounding acts of heroism and bravery. We have examined the staggering impact of the events of 9/11 on the American people and their amazing resilience and courage as they fought back. We have admired their determination to do their best to prevent another tragedy while preparing to respond if it becomes necessary.

We emerge from this investigation with enormous sympathy for the victims and their loved ones, and with enhanced respect for the American people. We recognize the formidable challenges that lie ahead. We also approach the task of recommendations with humility. We have  made a limited number of them. We decided consciously to focus on recommendations we believe to be most important, whose implementation can make the greatest difference. We came into this process with strong opinions about what would work. All of us have had to pause, reflect, and sometimes change our minds as we studied these problems and considered the views of others. We hope our report will encourage our fellow citizens to study, reflect—and act.
