hey everyone, there was an EXACT same explosion in Iran the day AFTER this happened
[link to news.yahoo.com
are we looking at a covert war going on here?
No, it says that a track-hoe or some kind of machine hit the pipe causing it to rupture and explode.
It could be just old things breaking down.
***Insert> regarding the US explosion:
I do think, however that it is an impact of some kind as things fly up and then a fireball.
If it was just a leak that caught fire, then the order would be reversed, fireball with flying debris.
The fact that debris was flying first confirms an impact of unknown type.
