Five days after a giant gas explosion reduced a Christchurch home to ruins,
experts outside an official investigation are still at a loss to understand how it happened.

Nine homes were damaged when a sudden blast obliterated a Marble Court house in the northern suburb of Northwood, sending chunks of roof tiles and other debris over the neighbourhood.
Neighbours and others who raced to the aid of the six people inside at the time were amazed that no one was killed. As of yesterday, one man remained in a critical condition at Christchurch, while another person was in a stable condition at Middlemore Hospital, which had a serious burns unit.
A gas contractor who worked on the house, which was having gas issues, just one day before it exploded, arrived at the chaotic scene on Friday and fronted to police officers.
