Dear Colonel:
Permit me to take this opportunity to thank you and your organization for the assistance you rendered this bureau in the investigation of the hijacking of the Northwest Orient Airliner on November 24, 1971.
Of particular assistance in the aerial search of the flight track were Majors Gottlieb and Goyins and their associates at the Portland Air Base.
Your cooperation and the assistance of members of your organization is most deeply appreciated by the FBI.
Very truly yours,
J. L. MATTSON Special Agent in Charge
