The possible significance of this well-covered incident spurred the colonel's group to extend and refine their activities. Their idea was to build a radiation-detection instrument in an empty wing tank and hang the tank on an F-47. Then when a UFO was reported they would fly a search pattern in the area and try to establish whether or not a certain sector of the sky was more radioactive than other sectors. Also, they proposed to build a highly directional detector for the F- 47 and attempt actually to track a UFO. The design of such equipment was started, but many delays occurred. Before the colonel's group could get any of the equipment built, some of the members left the lab for other jobs, and the colonel, who sparked the operation, was himself transferred elsewhere. The entire effort collapsed. The scientist was not surprised that I hadn't heard the story of the colonel's group. All the people involved, he said, had kept it quiet in order to avoid ridicule. The scientist added that he would be glad to give me all the data he had on the sightings of his "mineral club," and he told me where to get the information about the two astronomers and the colonel's group. Armed with the scientist's notes and recorder tapes, I left for my office at Wright-Patterson Air Force Base, Dayton. With the blessings of my chief, I started to run down the rest of the radiation information. The data we had, especially that from the scientist's "mineral club," had been thoroughly analyzed, but we thought that since we now had access to more general data something new and more significant might be found. First I contacted the government agency for which all of the people involved in these investigations had been working, the scientists who recorded the original incident, the scientist and his "mineral club," the colonel's group, and the rest. The people in the agency were very co-operative but stressed the fact that the activities I was investigating were strictly the extracurricular affairs of the scientists involved, had no official sanction, and should not be tied in with the agency in any way, shape, or form. This closed-door reaction was typical of how the words "flying saucer" seem to scare some people. They did help me locate the report on the original incident, however, and since it seemed to be the only existing copy, I arranged to borrow it. About this same time we located the two graduate astronomy students in New Mexico. Both now had their Ph.D.'s and held responsible jobs on highly classified projects. They repeated their story, which I had first heard from the scientist, but had kept no record of their activities. On one occasion, just before dawn on a Sunday morning, they were on the roof, making some meteorological observations. One of them was listening to the Geiger counter when he detected a definite increase in the clicking.
