This was after the couple of minutes it took to even notice this was going on and dig my phone out, navigating through menus to get to the camera portion. There were times when the flames were 'pouring' over the side of the flare stack, signifying it was full of a flammable liquid which filled the stack and all the piping leading to the stack. A major upset, and an all too common occurance in 'refinery row'.
