There's another related article on that site that I found interesting:
Google Declines To Comment On The Kentucky UFO Incident (http://www.ufo-blogger.com/2013/08/google-declines-comment-on-kentucky-ufo.html)

Google are saying that the Kentucky UFO is one of these? :o
It looks nothing like the image I posted but perhaps they have new balloons or Google are loons?
