unidentified target near the spot where the scientists in the car had seen the UFO, and it had been traveling north. A fighter had been scrambled, but when it got into the proper area, the radar
target was off the scope. The pilot glimpsed something that looked like the reported UFO, but before he could check further he had to turn into the sun to get on an interception course, and he lost
Several days passed before the radiation reports from all stations could be collected. When the reports did come in they showed that stations east of the laboratory,
on an approximate line with the radar track, had shown the highest increase in radiation. Stations west of the lab showed nothing.
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
