/ Choprer 4 CONCLUSIONS and RECOMMENDATIONS 4.1 CONCLUSIONS instru The balloon system left nothing to be desired in ease of 1 mentation of this type to altitude. The difficulties encounteredwiththeonan and telemetering systems could certainly be corrected by adequate testing in an environment including nuclear radiation of the intensity encountered here. The technique used seems well suited for tests in the 100 ,000-foot-altitude range and, if repeated with thoroughl: tested systems, should offer an excellent chance of success. ’ 4.2 RECOMMENDATIONS The Project 2.7 instrumentation performed satisfactorily, in view of the circumstances; but if the experiment should be repeated, the instrumentation should be tested on the ground in a nuclear-radiation environment. 35
