Last week, the UFO in this video caused officials to close the airport in bustling city of Hangzhou, China. As more footage from eyewitnesses goes online, we're starting to see artistic Hangzhou UFO vids - like this one.

I love the long, lazy arc of the UFO, accompanied by the classical music. It's like the 2001 of UFO footage.

The official story coming from China is that the incident is under investigation, and rumors are swirling that it's some kind of weapons test.
