Teenager spots UFO shaped black circle floating over his house, July 2015, UFO Sighting News.

Date of sighting: July 23, 2015
Location of sighting: Nottingham, England

This ring UFO was spotted by a boy in England this week as it flew over his house. Although it could be a smoke ring, such ring UFOs have been recorded by the US military and they confirmed it was a UFO (Sept 1957 Ft. Belvoir). So, only a closed mind would say its 100% chance of being a smoke ring, however...there is a chance, just not that big. I believe this to be a ring UFO. A UFO that is a drone, but usually stays high up in the clouds and it can also form a cloud around in in under a minute. UFOs cause animals to act strangely...so did you notice the birds flying all around it? It clearly got their attention. This is a true sign of a UFO. Another is that it took place during sunset. Which is the #1 most common time to see UFOs.
