Chevron refinery explosion that killed four people on 2 June 2011. Footage was taken just a couple of minutes after the storage tank exploded inside the Chevron plant in Pembroke Dock.

(At the time, we had no idea what was happening. We heard the tragic news later on the local radio. I know I made the video too long with unnecessary bits, but I just wanted to show the extent of the smoke over the time.)
