Peter Davenport was on C2CAM the other night, and he said that 2013 was the year he was going to put everything else aside and figure out what these are. He is getting more of these than ever before, and he does not believe they are all lanterns.
However, that being said, I have heard, and see online, a sealed up garment polybag now being used as a ginormous chinese lantern. It can blow around and sometimes catches on fire and makes a huge burst of light when it goes up in flames. But until that happens, it looks like the goodyear blimp it seems so large.
You should report it there.
