These views of the Committee were transmitted with the Panel reports by the Special Assistant to Defense, State, AEC, and CIA on March 17, 1959. On April 14 the Special Assistant forwarded a summary of the recommendations of the Panel on High Altitude Detection and the Panel on Seismic Improvement aimed at a future program for the improvement of our technical capabilities for detection and of our understanding of these problems. On April 23, the Special Assistant met with the Deputy Secretary of Defense and the Chairman of the Atomic Energy Commission on these recommendations. It was agreed that they should be imple- mented and responsibility for the implementation was accepted by the Department of Defense and the Atomic Energy Commission. On May 1, 1959, a Working Group of the Panel on High Altitude Detection met at the request of the Special Assistant to consider the special problem of the detection of tests between 50 and 100, 000 kilometers by apparatus located on the earth. A memorandum, dated May I, presented the Working Group's preliminary conclusions. A complete report will be prepared by June 1, 1959. 25.

Chaired by Dr. Kistiakowsky, it included four other individuals. Its report was submitted to the NSC on March 28, 1958. it concluded that, while the remote detection of long-range rockets leaving the atmosphere could be made almost certain by technical means, the discrimination between rockets for military and ''peaceful purposes" would be very difficult and that firings for "peaceful purposes" could supply the required SECRET
