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.

But we have to point out here that under the condition he describes it is impossible to produce an "excited radiation." The errors in Zhang Zhousheng's "theory" are many, and we are not going to point out further ones because of the limited space. However, from what we have already discussed we can see that almost every sentence in hi~ co-called "theory of UFO formation" is wrong! In fact, the observed parameters of the "7. 24 !I flying object are very different from those calculated based upon Zhang Zhousheng's "theory." We list both the calculated and observed parameters in the following table. From the table we can see that there is almost no correlation between the two at all!
