Strange object flying over Stadium, South Africa

On June 3, 2015, a Youtube user has discovered a possible UFO flying over a stadium in South Africa by using Google Street Views. What is it? A bird? An alien spacecraft? Another thing?

Scott C. Waring explains:

This UFO looks a lot like a jellyfish type of craft. The object has a hanging area that gets thinner as it reaches down, much like tentacles do.  The object was discovered by Youtube user DanielofDoria02 and its shows great detail once you zoom in. I had to auto change the color and contrast so we could see the UFOs actual color and shape. If you want to see it, just copy and paste the coordinates into the google search box on Google Earth.
