Lets start looking at what we know.
The chinese government reported that Xiaoshan Airport was shut down for one hour because of a 'hovering' object over the airport. Date 07/07/2010
Now lets look at the offered explanations so far?
*Returning Space Debris
List is incomplete:
* Private a/c with non-filed flight plan
* Chinese military vehicle on non-disclosed mission
* Non-Chinese military vehicle on ditto
* Falung Gong spoof
and the one I think needs further investigation
* Approaching aircrew's misperception of something as a 'light over airport' that the control tower could not locate on radar, and therefore had to
worry about where it might be, so incoming flights were briefly warned off.
The 'something' should be bright and clearly noticeable to the crew approaching the airport, as reported in several lengthy news stories.
It could look like an aircraft landing lights, or other running lights (less bright).
Apparently even though visible to the aircrew it was not visible to ground observers. Such sources do indeed exist -- bright objects near the horizon
that are obscured by horizon clutter to on-the-ground observers but are clearly visible to airborne observers.
But what 'bright object'? Therein hangs the tale....
We need to know:
a) which direction the airliner was approaching the single runway -- 07 or 25?
b) their initial description of the sighting
c) whether that was the trigger for the radar screen examination, and its results
d) what would have been visible in the sky almost two hours after sunset in the direction the crew would have been looking.
e) the cloud conditions that could have masked celestial objects from airliner's view
It's a great pity that nobody has reported in any of the parallel threads on this subject, that they have made any progress on any of these
But they ought to keep the Barnaul Airport UFO-shutdown in early 2001 in their minds (and the ironclad prosaic explanation for that
intriguing-sounding case), in consideration of candidate explanations this time.
