Another video of Strange Sounds from the Sky in Halton, UK on the 23rd of August 2012. From the comments, we learn that these Strange Sounds were heard by different people in the same area. Definitely not a hoax!
The video recorded the last three bursts of this strange sounds. The sounds are facinating write the recorder. The movie was recorded near ICI (metallurgy company) so it could be from them but the recorder has never heard anything like this before in all his time living there.
