UFO in China Closes Xiaoshan Airport - UFO Sighting

A UFO sighting in China Xiaoshan airport closed the airport. UFO in China is one of the most controversial 2010 UFO sightings yet. The observation comes a few days after another observation that was claimed to be nothing more than debris from a U.S. intercontinental ballistic missile.
What does the UFO sighting mean? Although there are claims that military involvement is demonstrated by the Russian, Chinese and American governments are surprisingly tight lipped about the whole ordeal that those who fear global military issues a bit nervous. It excites those who at least believe in UFOs and aliens.
If the UFO was indeed an extraterrestrial source, it would mean that the world as we know it will change? Would mean that instead of other nations that our biggest threat is actually located in a different world?
There was a high profile UFO sighting in China in 2009, which was reasonably close to an eclipse seen. Could it be that if there are aliens, their first contact will be the Chinese?
It could just be that the Chinese UFO sighting was little more than just some space debris or a section of an intercontinental missile. It may be that it is part of a top-secret military exercise or something else. Still not, there are many looking at this strange event as an indication that there is something outside our world who would try to contact kunnen to do with us.
