Office of the Secretary of Defense · 9 pages · text from the file's own layer

This is an edited English translation, dated 11 April 1983, prepared by the Foreign Technology Division at Wright-Patterson AFB, of a September 1982 article by Liu Yan in the Chinese journal Tianwen Aihaozhe. The article covers the spiral luminous object that several million people in western China saw on July 24, 1981. It rejects Zhang Zhousheng's claim that the object was a Cassiopeia meteoroid he had predicted. The author concludes it was most probably a man-made flying machine several hundred km up.

What Zhang Zhousheng has predicted is, therefore, not a
meteoroid that will become a UFO, but at most the apparent location
of the radiant point of a certain meteoric swarm on the celestial
sphere. Here, moreover, we have also to add a note that Cassiopeia
is not truly the celestial region in correspondence with his pre-
diction. To the observers in our country, the celestial region in
correspondence with his prediction should be around the Swan, Eagle,
Harp, etc •
Therefore, even if we accept his theory, his prediction is yet
not only vague, but also self-contradictory!
The Shape of UFO and Zhang Zhousheng's "Theory"
The "7.24" flying object is a hug~ luminous body, for which
Zhang Zhousheng has made a "theoretical" explanation. He says:
In the Universe "a few meteoroids of large mass that carry volatile
matter have an ionosphere on their surface. When these meteoroids
enter the geomagnetic field from the planetary space to about several
thousand km above the Earth's surface, the charged particles in the
meteoroid ionosphere under the action of the Lorentz force will be
released from the confinement of the meteoroid's self-gravity and
form a particle stream along the geomagnetic field in a spiral motion
of changing radius." And the illumination of the spiral body is
"the excited radiation" due to the mutual impact between the charged
particles.
This "theory" seems to glorify the "7.24" UFO; however, this
"theory" can also be easily proved to be groundless.
First, the mass and gravity of a meteoroid are so small that
no gaseous matter can stay on its surface. How can it be that "on
the surface of the small heavenly body •.. forms a sphere which
resembles the structure of the ionosphere in the outer atmosphere
of the Earth and other planets?"
