Explosion rocks Texas as chemical plant blows up following gas pipeline breach
Evacuations ordered after Texas gas pipeline explodes
Images taken of the fire in La Porte shows an extremely large jet of fire forcing into the sky, bringing thick black smoke with it.
First of all, it wasn't a "plant". It was a Kinder Morgan pipeline.
Secondly, nothing "blew up". Pipeline ruptured or valve failure.
Thirdly, it wasn't a "gas" pipeline. Natural gas burns clean. This was probably mixed hydrocarbons.
If you watch the videos, none of the locals are panicking. They know the drill.
