His house was "shaking and shuddering" so much he thought an aeroplane had landed on it - the walls had collapsed and the roof had caved in.

Mr Mitchell said his family ran outside and seeing a "huge, huge, fireball", realised the oil depot, some 400m away, had exploded.

Alex Chown, from the Environment Agency, said: "The primary issue was obviously the overfilling system, that was identified as a fault and resulted in an immediate response across the industry to put that right to ensure the lessons learned were adopted straight away."
