UFO Over China Causing Airport Closure – Video Within

This incident happened a few days ago. An UFO (Unidentified Flying Object) had caused Xiaoshan airport in the eastern city of Hangzhou to stop operation for a period of time while the ground controllers were busy diverting flights and trying to figure out what happen.

Till today, there was no clear explanation on this sightings. Here is a video and some closeups of the object in the sky.

And also, another bizarre sighting on the 30th June has caused some uproar in China. Officials think that it might be a test missile from the US. However, if you look at the video footage, there is nothing like what you have seen (IMHO).

So, any experts here to explain what happen?
