San Diego UFO debunked

This incredible picture of what appeared to be a massive UFO in the sky over San Diego has finally been debunked, the result may surprise you.

It turns out that this UFO is nothing more than TV antennas on the top of a very large mountain. Many San Diego citizens thought that it was a UFO and some even reported the sighting to the police, my only question is: why did they not know that it was the antennas? i mean i presume that they have lived there for quite a while and would know, even if it was covered by thick fog, that there was a mountain there.

So what do you think? was this done on purpose by the media as a joke to real believers? or do you think that the San Diego news station and its citizens are that stupid?
