In the late sixties there was a film set in China concerning a flying saucer. The film was entitled The Bamboo Saucer.
It wasn't one of the world's best UFO films because really, the plot revolved more around the groups traveling to the site of the UFO and tensions between Russia, China and the U.S. But having said that, it was an interesting movies because the UFO - from the audience perspective - is treated almost as an every-day thing with the film concentrating on power games, struggles, conflict and so forth.
Apparently, a Chinese airport was recently closed after a UFO appearance.
Of course, the whole thing is ridiculed and the event is described as sunlight reflecting off conventional aircraft.
America, Australia, Russia - almost every country has reports of UFOs and many are explainable. But there are those which defy explanation.
Given the limited ability to get truth out of a country which has a history of genocide and atrocities, it is hard to imagine how this story could ever have gotten to the world press. At least, it is hard to imagine if it was a simple case of 'sunlight reflecting off conventional aircraft'. But if it wasn't.....
Many airports have stray or unexpected aircraft violating airspace. But they don't usually close the airport. Of course, China might be different.
It is important to realize, though, that Tibet and China (different countries by the way guys) both have a history of UFO phenomenon. Proven or otherwise, they are both significant locations in terms of alleged (i.e. neither proven nor dis-proven) extraterrestrial activity.
Is this recent sighting just sunlight? Or is it more interesting?
I guess you have to make your own mind up about that.
