Re: "destroyed in a Buncefield oil depot fire"
It is misleading to describe the event as "a Buncefield oil depot fire". A colleague of mine was at home in bed when it happened, several miles away, and his entire house shook with the force of the explosion. According to the BBC it was the largest explosion in the UK since the second world war, and was audible in parts of the Netherlands:

"On the morning of 11 December 2005, the UK experienced its largest explosion since World War Two. The huge blast at the Buncefield fuel depot in Hemel Hempstead was heard as far away as the Netherlands and shrouded much of south-east England in smoke. "
