I am sure you have all seen the pictures of the house explosion in Christchurch, A suspected gas explosion with work being carried out on the dwelling the day before for some gas related issue.
I am sure the investigation will show the exact problem.
It amazes me that nobody was killed, 5 people in the house itself, I mean look at the devastation and no death it just amazes me. I do understand some people are in a pretty bad way in hospital, My thought's go out to them and all the people around that area that have been badly affected.
