CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, from left, Thomas Keller, program manager with Chenega Security and Support Solutions on the Kennedy Protective Services contract, and Kennedy Space Center Director Robert Cabana stand at attention during the 9/11 memorial dedication ceremony at Fire Station 1. Kennedy Fire and Rescue Services commemorated the 11th anniversary of 9/11 with a ceremony that included a minute of silence at 10:28 a.m., which was the moment of collapse of the north tower of the World Trade Center. Kennedy center-wide emergency units dispatched by Fire Control engaged in one-minute sirens, the new memorial was dedicated and the Honor Guard performed a flag-folding ceremony.
