UFO or Lenticular Cloud?
This Lenticular Cloud/UFO was seen over Xiamen city, southeastern China in Fujian Province.
Many Ufologists will tell you that many UFO are reported coming out of clouds like these. It is believed that UFO form clouds like these to hide in when they are unable to cloak themselves.
Quoted by Scott Waring:
"This was taken during sunset, a moment when the cloak of the UFO becomes…vulnerable. Let me explain briefly. When light is bent around the UFO, it comes from above it from the sun. This light has to bend 180 degrees around the UFO to make it look invisible. However if the sun is setting, one side of the UFO shield must now bend the light 260 degrees which it cannot do and thus the UFOs are revealed for 1-15 minutes during sunset."
