pr. Ce Le Dunham DMA, at Dr. Libby's suggestion, has asked our laboratories to study fireball characteristics as they may relate to the debris distribution and scavenging, and to prepare a report on the subject. AFSWP, P&M and DMA are all involved to a greater or lesser degree in this project, therefore, it is proposed that B&M and DMA sponsor jointly, a symposium to be held shortly after the first of the calendar year. In the meantime, a free exchange of information among the inte< ested parties in preparation for the symposium is desired. Will you please advise us of your desires on the sponsorship of the symposium and any other pertinent information that would best serve the purpose of getting at the problem as desired by the Commissioners. 3 gadier Generel, USA Hirector of Military Application U/ eeeEre ee SSa t a ee shank SSuk eae ies ES % —! a) 50001b8 - 50
