Film captures moment West London office block collapsed during demolition.
Within just a few hours of the partial collapse of the Hounslow House collapse earlier this week, DemolitionNews was on site to capture the immediate aftermath.
But now, with investigations ongoing, dramatic new footage has emerged that shows the very moment the seven storey block came down. And while it sheds no new light on the precise cause of the partial collapse, the new films certainly illustrate just how pedestrians, passing cars and packed passenger buses came to disaster.
