Hi, I'm Carlos Santillan in Tlalnepantla Mexico City
Recorded on saturday december 27th 2008 this weird looking object I do not know what it was.
I do not want to speculate by calling it a balloon nor a UFO nor a flying humanoid. Wacth the video, & judge by yourself. At the end of the video there are stills.
