Question: What is the name of the July 2001 FBI memo warning that suspected bin Laden associates were enrolling at Arizona flight schools?

Answer: The Phoenix Memo, sent to bureau headquarters on July 10, 2001, by Special Agent Kenneth Williams. Headquarters did not act on its recommendations. Two months later, hijacker-pilot Hani Hanjour—who trained at Scottsdale, Mesa, and Phoenix flight schools—flew American Airlines Flight 77 into the Pentagon.
