At least six of White Sands's rockets have circled. One missed the control blockhouse by only about 600 feet...
Karsch is more worried about the rockets that pick nearly right courses which would carry them far outside the target area. To deal with them, he has set up a system he calls a "safety screen...
...observers watch the rocket with telescopes. One station notes the east-west component in the rocket's course; the other the north-south component. Set up in front of each telescope is a "sky screen" with curved lines on it. If the rocket crosses one of these lines, it is likely to fly out of bounds...
Watchful Brain. Karsch's simple safety screen has worked well, but recently he got a better gadget: an "Impact Predictor," which can tell in advance just where each rocket will hit. Two observers track the rocket with telescopes. The information from the stations is fed automatically into an electronic brain (analogue computer) which can solve complicated equations almost instantaneously...
