This was a really good find over on ATS. I am not saying there was not an explosion or why the news station lied and said they were showing footage of the West Texas fertilizer plant explosion, but they did lie. It was clearly old video from an explosion in Nevada from 1988 which they said was footage of West Texas. I recently did post a questionable video showing what appeared to be something fired at that plant after the fire had started which I will post following this footage.
Now, there is no way to tell if something was definitely fired at the plant from the information in the second video, but it does show something appearing to come into the plant from the left. The only questionable thing I found about this situation was that the company that owned that plant was in a lawsuit with Monsanto.
