On September 11, 2001, White House Chief of Staff Andrew Card walked into an elementary school classroom in Sarasota, Florida, and whispered into President George W. Bush's ear during a scheduled visit. He delivered the historic and chilling message: "A second plane hit the second tower. America is under attack." This moment, captured vividly by photographers and broadcast worldwide, marked the exact second the President and the nation transitioned from viewing the initial World Trade Center crash as a tragic accident to realizing they were facing a coordinated, unprecedented act of terrorism. Card made the deliberate choice to keep his delivery calm, measured, and quiet to prevent the classroom of young children from panicking and to avoid alarming the media pack stationed at the back of the room before the administration could fully process the gravity of the unfolding national security crisis.
