ed a map out of his
file to show me what he meant. It was a map that he had used to plot
the spot where a meteorite had hit the earth. I believe it was in
Kansas. The map had been prepared from information he had obtained
from dozens of people who had seen the meteorite come flaming toward
the earth. At each spot where an observer was standing he'd drawn in
the observer's line of sight to the meteorite. From the dozens of
observers he had obtained dozens of lines of sight. The lines all
converged to give Dr. La Paz a plot of the meteorite's downward
trajectory. Then he had been able to plot the spot where it had
struck the earth. He and his crew went to the marked area, probed the
ground with long steel poles, and found the meteorite.

This was just one case that he showed me. He had records of many
more similar successful expeditions in his file.

Then he showed me some other maps. The plotted lines looked
identical to the ones on the map I'd just seen. Dr. La Paz had used
the same techniques on these plots and had marked an area where he
wanted to search. He had searched the area many times but he had
never found anything.

These were plots of the path of a green fireball.

When Dr. La Paz had finished, I had one last question, "What do you
think they are?"

He weighed the question for a few seconds--then he said that all he
cared to say was that he didn't think that they were a natural
phenomenon. He thought that maybe someday one would hit the earth and
the mystery would be solved. He hoped that they were a natural
phenomenon.

After my talk with Dr. La Paz I can well understand his apparent
calmness on the night of September 18, 1954, when the newspaper
reporter called him to find out if he planned to investigate this
latest green fireball report. He was speaking from experience, not
indifference, when he said, "But I don't expect to find anything."

If the green fireballs are back, I hope that Dr. La Paz gets an
answer this time.

The story of the UFO now goes back to late January 1949, the time
when the Air Force was in the midst of the green fireball mystery. In
another part of the country another odd series of events was taking
place. The center of activity was a highly secret area that can't be
named, and the recipient of the UFO's, which were formations of
little lights, was the U.S. Army.

The series of incidents started when military patrols who were
protecting the area began to report seeing f
