I just found these on the 9/11 Commission Report:
39. NTSB report, "Flight Path Study-American Airlines Flight 11," Feb. 19, 2002.
41. NTSB report, "Flight Path Study-United Airlines 175," Feb. 19, 2002; NTSB report, Air Traffic Control Recording-United Airlines Flight 175, Dec. 21, 2001.
53. 61. See NTSB report, "Flight Path Study-American Airlines Flight 77," Feb. 19, 2002

I also noticed they didn't have a flight path study for Flight 93. They only had this:
70. On FDR, see NTSB report, "Specialist's Factual Report of Investigation-Digital Flight Data Recorder" for United Airlines Flight 93, Feb. 15, 2002
