ffort to run down the actual film and the analysis. The files at
White Sands, like all files, evidently weren't very good, because the
original reports were gone. I did contact a major who was very co-
operative and offered to try to find the people who had worked on the
analysis of the film. His report, after talking to two men who had
done the analysis, was what I'd expected--nothing concrete except
that the UFO's were unknowns. He did say that by putting a correction
factor in the data gathered by the two cameras they were able to
arrive at a rough estimate of speed, altitude, and size. The UFO was
"higher than 40,000 feet, traveling over 2,000 miles per hour, and it
was over 300 feet in diameter." He cautioned me, however, that these
figures were only estimates, based on the possibly erroneous
correction factor; therefore they weren't proof of anything--except
that something was in the air.

The people at White Sands continued to be on the alert for UFO's
while the camera stations were in operation because they realized
that if the flight path of a UFO could be accurately plotted and
timed it could be positively identified. But no more UFO's showed up.

One day Lieutenant Cummings came over to my desk and dropped a stack
of reports in front of me. "All radar reports," he said, "and I'm
getting more and more of them every day."

Radar reports, I knew, had always been a controversial point in UFO
history, and if more and more radar reports were coming in, there was
no doubt that an already controversial issue was going to be
compounded.

To understand why there is always some disagreement whenever a
flying saucer is picked up on radar, it is necessary to know a little
bit about how radar operates.

Basically radar is nothing but a piece of electronic equipment that
"shouts" out a radio wave and "listens" for the echo. By "knowing"
how fast the radio, or radar, wave travels and from which direction
the echo is coming, the radar tells the direction and distance of the
object that is causing the echo. Any "solid" object like an airplane,
bird, ship, or even a moisture-laden cloud can cause a radar echo.
When the echo comes back to the radar set, the radar operator doesn't
have to listen for it and time it because this is all done for him by
the radar set and he sees the "answer" on his radarscope--a kind of a
round TV screen. What the radar operator sees is a bright dot, called
a "blip" or a "return." The location
