Cn Aa ae ee ! Lal ar j L A in ail areas. Thus, } I wi I experimental test programs in the past have included projects designed to expand knowledge in both the developmental and effects fields. Operational and scientific compromises nave been necessary in planning the test operations so that both missions could be accomplished. As in any compro~ mise, each interest has suffered in some degree, due largely to the co-equal status of interest in each test. (masmuch as its yield was thought to be most accurately predictable and inost nearly in the order of magnitude desired for a large weapons effects program, most of the military structures and materials tests were designed around this shot, The joint bio-medical program was also largely tied to this ce Moe shot. , The changes were OO costly in time, manpower, and moncy and at the same time prevented a full realization of the laboratory objective for proof-testing.
