Another Explosion?

There was yet another explosion at the BP plant in TxCity. UGH. I will put in a link to the local paper tomorrow because I'll prefer it's reporting of it. All the news has said that the explosion was around 6pm. I was blessed for I wasn't out driving by the plant to get home at that time. However, we are very curious about the explosion because we heard a small boom around 7:30. I have no clue what that was about then. I saw no smoke in the sky when I was driving home around 6:30pm, so it doesn't make any sense to me with the news reports I've heard on the local news and read on line. Thankfully there have been NO injuries reported. Lets just hope it doesn't stink too much in the morning to get to grandma's home.
