Abstract : This flight was carried out with two major aims: First, to test the Stratoscope II Balloon System with regard to its ability to carry a substantially heavier payload than previously, and second, to test Vitro's new instrumentation for side arm orientation on landing. The first aim was important because the weight of Stratoscope II had steadily increased by the addition of necessary auxiliary equipment and had reached a value so that the balloon ballast that could be carried without increasing the total weight had become uncomfortably low (careful engineering investigations by Vitro had previously shown that the present Stratoscope Balloon System could carry a weight noticeably higher than that carried in previous flights without reducing the safety factors to dangerous values). The second aim on the other hand was directed towards further reducing the probable damage to the telescope on landing. (Author)
