For triggering or diverting natural lightning strokes, the electrical properties of a large rocket motor and its exhaust plume were simulated by deploying long wires from small rockets. A wire length of between one and two thousand feet should adequately simulate the conductive effects of an Apollo vehicle. Various small rocket motors were considered, and the Little John was selected for study in an experimental program. The wire was deployed from an on-board package. After estimating the forces acting on the wire, a computer program for simulating a flight was developed. The experimental results gave a measure of the very difficult to estimate air drag coefficient as about three times that estimated earlier. (Author)
