During the summer of 1962 several Phase I and Phase II BANSHEE events were scheduled at White Sands Missile Range in an attempt to conclude these phases of the operation. Unavoidable weather conditions prevented any Phase II events missile-borne charge, instrumented balloon from being completed, but five Phase I events charge and instrumentation canisters on balloon dragline were accomplished. Of these, three were successfully covered by fireball photo graphy. The altitudes of these three events were 103,726 feet B-20, 103,370 feet B-20A, and 81,258 feet B-24A. Data reduction and analysis were performed along the lines established in the earlier report. Radius versus time plots of the 1962 data indicate, as would be expected, a more rapid expansion rate of the fireball at early-times. Reduced radius versus reduced time plots are found to be in fair agreement with the scaled data from earlier, events for time values. Beyond this time value, the higher altitude data produce larger radius values, and do not exhibit the gradual tapering off observed for the earlier events.
