Abstract : The Operation Tumbler-Snapper material-velocity experiments were instrumented in a manner similar to that used on Operation Buster-Jangle. Methods of labeling air for photographic recording consisted of mortars and JATO's. In addition, the firing of high-altitude smoke projectiles from guns was included as a feasibility test for similar instrumentation on Operation Ivy. Tumbler shots 1 to 4 and Tumbler-Snapper shots 5 and 8 were instrumented, and data were obtained on all shots. This part of the report discusses the analysis of data for peak material velocity and overpressure as a function of distance. Further data on time of arrival and thermal shock waves are presented; the latter are in preliminary form. Additional photographic records, not yet analyzed, are discussed, and the extent and value of such future analyses are briefly described. Two appendixes present the analytical method of data reduction in detail.
