In the words of Mr. Scott "The more complex the plumbing, the easier it is to clog up the drain". I used that once at EK to explain why we were having problems with one of the new scale up units. I got a lot of mixed reactions.

That's the problem, Ron, there are so many people in this crazy modern world that don't know Star Trek quotes by heart!
So the usual reaction you will get from someone that (foolishly) doesn't commit great Scottish rants or Shatnerian monologues to memory is: "What the HELL is this guy talking about?"
To add a quote pertinant to this situation: "RISK is PART of the business. . . That's, why. . . we're out here. Thats, why. . . we're ABOARD her."
To put it more succinctly though, this "risk" is totally avoidable by TESTING equipment, repeatly, before you shoot. Don't make any assumptions about the functionality of anything.
