bservers had seen several of the
green fireballs and said that this object was similar in all respects
except that the color was a brilliant blue-white.

With the disappearance of the fireball, the counter once more
settled down to a steady click per second. They added that once
before they had detected a similar increase in the frequency of the
clicks but had seen nothing in the sky.

In telling their story, both astronomers stressed the point that
their data were open to a great deal of criticism, mainly because of
the limited instrumentation they had used. We agreed. Still their
work tended to support the findings of the more elaborate and
systematic radiation investigations.

The gods who watch over the UFO project were smiling about this
time, because one morning I got a call from a colonel on Wright-
Patterson Air Force Base. He was going to be in our area that morning
and planned to stop in to see me.

He arrived in a few minutes and turned out to be none other than the
colonel who had headed the group which had investigated UFO's and
radiation at the eastern laboratory. He repeated his story. It was
the same as I had heard from the scientist, with a few insignificant
changes. The colonel had no records of his group's operations, but
knew who had them. He promised to get a wire off to the person
immediately, which he did.

The answer was a bit disappointing. During the intervening months
the data had been scattered out among the members of the colonel's
group, and when the group broke up, so did its collection of records.

So all we had to fall back on was the colonel's word, but since he
now was heading a top-priority project at Wright, it would be
difficult not to believe him.

After obtaining the colonel's story, we collected all available data
concerning known incidents in which there seemed to be a correlation
between the visual sighting of UFO's and the presence of excess
atomic radiation in the area of the sightings.

There was one last thing to do. I wanted to take the dates and times
of all the reported radiation increases and check them against all
sources of UFO reports. This project would take a lot of leg work and
digging, but I felt that it would offer the most positive and
complete evidence we could assemble as to whether or not a
correlation existed.

Accordingly, we dug into our files, ADC radar logs, press wire
service files, newspaper morgues in the sighting area, and the files
of
