“In July [10] 2001, a highly regarded 41-year-old FBI counterterrorism agent in Phoenix named Kenneth Williams was investigating suspected Islamic terrorists when he noticed that several of them were taking lessons to fly airplanes. Williams became more suspicious after he heard that some of the men had been asking questions about airport security procedures. His supervisor, Bill Kurtz, thought Williams might be onto something and proposed monitoring civil aviation schools to see if bin Laden’s operatives had infiltrated them…Kurtz’s proposal was completely ignored.”
