Interesting personal link with this my brother was working in that area when it happened. He was part of a team building a Fibre Optic network for British Telecom and they use to live in the huge trucks they used for the project. They had been parked just behind the garage that the debris crashed on. The day before though they decided to move elsewhere as they wanted a night out in town. If they hadn't moved they would have been in serious trouble. Guardian Angels watching them that night.
