Upon cessation of the most recent terrain search in Clark County, Washington it is felt that the following comments are pertinent since they come from one individual who has partic- ipated in every search operation which have a total time expenditure of approximately 9 weeks.
The search conducted by the United States Army was the best effort which could be expended considering the number of personnel involved, logistic and support problems, weather and terrain factors. This is pointed out by one speaking from actual experience, intimately acquainted with details of the various searches, since there appears to have arisen some question on the adequacy of the military search.
The searches conducted by Agent personnel were also the best effort which could be put forth considering the same problems mentioned above.
The most recent search appears to have been based upon the securing of new data which corrected the most logical spot at which the hijacker exited from the aircraft, which resulted in the moving of what has been referred to in past communications as point A. However no concrete information has been developed that the parachute of the hijacker did not open and the renewing of the search of the terrain at new point A appears to have been based on mere conjecture that the chute did not in fact deploy.
In view of the above it is respectfully and earnestly recommended that absent concrete information concerning the hijacker or evidence in this matter being in the searched or unsearched terrain that no further terrain searches be undertaken. It is felt that to do so would result in an unwarranted expenditure of agent time and effort and an expenditure of Bureau funds which is not economically feasible or justified.
