Re memo of SA THOMAS J. MANNING, dated 10/24/72.

Referenced communication advised that [REDACTED] Washington, had furnished the following information:

On the night of NORJAK, a jet airliner flew over his home at about 5,000 feet from the ground. [REDACTED] home is considerably east of the search area, and if the jet airliner that flew over his home was the hijacked Boeing 727, this would indicate an error was made in the calculations of the search area.

Standard U.S. Government interoffice memo header. Addressed to SAC Seattle, file 164-81, from an unidentified Special Agent (name redacted under b6/b7C), dated October 31, 1972. Subject is NORJAK, Office of Origin Seattle. References a prior memo by SA Thomas J. Manning dated 10/24/72. A source in Washington (name and location redacted) reported that on the night of the NORJAK hijacking, a jet airliner flew over his home at about 5,000 feet. Since his home is considerably east of the search area, if the aircraft was the hijacked Boeing 727 this would suggest errors in the flight path / search area calculations. Three investigative leads assigned to the Seattle field office: (1) Contact Northwest Orient Airlines to recalculate the flight path and drop point; (2) Review radar information on the NWA 727 flight to verify flight path calculations; (3) Review logs in File 164-81 to determine if the UNSUB could have jumped at a different time than previously calculated. Administrative markings including 'ARMED AND DANGEROUS' warning, typist initials RNN:jgm with 3 copies noted, file/serial stamps dated approximately October 3, 1972, and a DB Cooper tracking number 9842. Handwritten marginal notes indicating leads 2 and 3 were completed ('DONE'). Privacy exemption codes b6 and b7C marked alongside redacted portions throughout the right margin. Standard government form footer promoting U.S. Savings Bonds.
