On Tuesday 23 February 2016, part of the boiler house building collapsed at Didcot Power Station; one person was declared dead, five injured and three missing. All were believed to have been preparing the site for demolition. On Sunday 17 July 2016, what remained of the structure was demolished in a controlled explosion. The bodies of the three missing men were still in the remains at that time. A spokesman said that because of the instability of the structure, it had not been possible to recover the three bodies. For safety reasons, robots were used to place the explosive charges, and the site was demolished just after 6 o'clock in the morning (BST).
