On September 11, 2001 the definition of National Security changed for most U.S. citizens. For an entire postwar generation, "National Security" meant protection from nuclear attack. On that day, Americans redefined that threat.
On September 11, 2001 three hijacked airliners hit three separate buildings with such precision and skill that many observers believe those flights were controlled by something other than the poorly trained hijackers in the cockpits.
This report contends that not only were the buildings targets, but that specific offices within each building were the designated targets. These offices unknowingly held information which if exposed, subsequently would expose a national security secret of unimaginable magnitude. Protecting that secret was the motivation for the September 11th attacks.
This report is about that national security secret: its origins and impact. The intent of the report is to provide a context for understanding the events of September 11th rather than to define exactly what happened that day.
