SCHRIEVER AIR FORCE BASE, Colo. -- Col. Marcus Caughey, 50th Space Wing vice commander, was the key speaker at Schriever Air Force Base's 911 ceremony held here Sept. 11. The colonel gave personal accounts of the heroism he witnessed while working in the Pentagon on the day it was attacked in 2001. The memorial ceremony featured a wreath placement as well as a moment of silence while the bell was wrung in three secessions of five rings to honor those lost 13 years ago.
