Amen to that.
We used to tour Marshall Space Flight Center. They would take us out to the test area where in the 60's they tested the first stage of the Saturn V. It was cooled in the same manner as the launchpads at Kennedy. I believe they said there was 81 thousand holes in the blast deflector that water was pumped through. There are a couple of tanks close to the stand that held a couple million gallons of water.
Sure wish I could have been in that block house the day they test fired the complete first stage.
