On 12/27/71, at 3:50 p.m., SAC J. EARL MILNES, Seattle Office, telephonically advised he had worked out a plan with Northwest Airlines to utilize the same plane as in instant skyjacking to retrace its route, with the plan being to drop a dummy under identical circumstances over the believed target area, in an effort to trace descent pattern.

SAC MILNES advised it was desirable to have an airplane present to follow the falling dummy; he suggested SA RALPH P. HIMMELSBACH, Portland Division, whom he knows to be a pilot and an airplane owner. Mr. MILNES was advised that appropriate inquiry would be made on this end and he would be recontacted later, probably on 12/28/71.

SA HIMMELSBACH was contacted at home, where he is on annual leave, and he stated that while he had intended to remain on AL on Monday, 1/3/72, he would consider coming back on duty for this project, recognizing the critical nature of it; however, he stated that climatic conditions might dictate that the matter be called off. He advised he would be in touch with ASAC RUEHL on 12/28/71 regarding this projected flight.
