Didcot power station explosion caught on camera
Part of the main building at Didcot A Power Station has been demolished using 200kg (440lb) of explosives.
A section of the 48m (157ft)-high main building came down just after 09:00 BST and was captured on film by demolition firm Coleman and Company.
Three of its six cooling towers were blown up in July last year.
The rest of the main building will be demolished later this year.
