I doubt anyone here is keeping track (or has even heard) of the Buga sphere story - a metallic sphere that was filmed flying around Buga, Columbia earliewr this year before hitting a powerline and descending to the ground. It was captured and has been analysed by scientists in Mexico. Plenty about this on YouTube and is covered by the usual tabloids who are not afraid to report on this kind of thing. Since, other spheres have been captured on video elsewhere in Columbia and even China.
