By using this side to side motion with the line we can cover the whole locked. And C wins. Where it was circles you know more -- Fight using -- side to side motion with the stream. We can get the whole width of the store in addition we can lower the -- height. And get way back into the occupancy by doing that we can listen to the sound of the stream hitting the wall. A lot of times commercial building fires -- the -- By moving upstream horizontally across the -- we may actually finding entrance to the -- -- stock room.
