WDOS BETsESN 100,000 and 500,000 FEET ALTITUDE 5.3.1 Introduction The ability to obtain a cloud saxple from either Teak or Orange was ¢ce~pendent upon the sampling iastriceaotation vithin the carrier and the capa~ bility of the rocset to hit the debris. This capability of penetration, in turn, sas dependent upon the accuracy of the Redstone in positioning the device at its prezeternined position, che accuracy of the sa=pling rocket in bitting its target, and the ability to prognosticate the cloud's coordinates with tine after burst. The Latter ability requires accurate inforsation on size, rate of rise, and lateral movement of the cloud with winds. Initial plannizg for Teax event called for penetration of the debris at burst plus 40 seconds and burst plus 80 seconds. These tines, resulting fron original estimates of the cloud size, were based on cualitative extrapolation fron low-level burst daca discussed in Section 5.1, indicated rescheduling of the samples so that rocket would be over the burst at zero tise and the second roccet would pass through the burst area 2t zero plus <0 seconds. The first rectzet would be approxizately +0,000 feet above anticisated burst. The change in tining obviated the meed for a wiod forecast on Teas, since the £0-second interval between burse and penetration would reduce the wind influence on the cloud to a neglizgible value.
