a disk shape object moving with high speedabout 9.30pm, I discuss something with my dad. I saw like orange color flying object move from east to west above my dad's house. At first I think is a chinese lan deng which it will drop very soon.But this object seem too fast and stabil when it moving. It seem going up and not going down. I sure this is a fly object and when it is close I can see a disk shape. The UFO slow a bit on top of us and seem like also notice we look at them. After few mins it continue with fast and stabil speed and disapear behind the crown.This is fifth time I saw UFO in this two years. Last time is more close, more big, we even can see the "windows" of UFO.
