a MEDDE SUBJECT: ee ae a a | Reappraisal of Biomedical Project "Hardtack" 7. I am convinced of the capability of the medical unit under the Project Officer to take maximum advantage of all opportunities to effect a successful experiment. Nevertheless, there are additional factors, as mentioned in paragraph 3, above, and in the Project Officer's report, which may result in failure. A full knowledge and awareness of those factors must be recognized. Failure for any of those reasons lies beyond my control and responsibility. 8. I believe and hope that the Project will yield vital data applicable to this category of weapons as well as basic information of critical importance to the understanding of biomedical effects of nuclear weapons in general. 3 Incls 1.
