@ @ 164-81 Unsub may have made a trial run prior to NORJAK to perfect his skyjack plan, therefore, leads were set out on 7/23/73 to determine the feasibility of obtaining passenger lists for all Northwest Orient Airline flights from Portland to Seattle during the period 11/10/71 to 11/23/71. If passenger lists of flights from Portland to Seattle for above described period can be obt:.ined, then names on this list would be com- pared to NORJAK indices and other lists currently on file at Seattle, in order to possibly identify Unsub. Prior to the 1973 hunting season which began in October in the Pacific Northwest, information was disseminated concerning this matter to all Washington State Game Wardens responsible for the area to which Unsub parachuted. The Game Wardens are currently making this information available to all hunters they encounter in this area. As of 11/23/73, no positive results have been obtained. The information being made available to the hunters is as follows; DB Cooper-12153
