The Troupe had scared up an F-2 early in the day. The spike had come very suddenly, and rather unexpectedly, and out in the middle of nowhere. And that was all to the good, because the Troupe had had the spike all to themselves. Greg and Carol had taped the entire development sequence, from wall cloud to rope-out, at close range from the ground. Buzzard and Martha had nailed it with chaff, so Peter and Joanne in the Radar Bus had gotten some very good internal data. That one had to be counted a success.
