I also want to note that the url([http://cgbm.calet.jp/cgbm_trigger/flight/1399729386/index.html](http://cgbm.calet.jp/cgbm_trigger/flight/1399729386index.html)) doesn't link to anything. I've added for completeness since the fields do contain data and the url is present in the text notices as well.
