A lot said above is true-Because of my position maintaining a fleet I get to deal with some engineers and some corporate on different levels. I have found a few that don't talk much but do ask questions-and it's getting a lot more rare these days. I have sat and stood for long lengths of time waiting for most to get done preaching their knowledge and product. When they are done-I remind them I'm the one dealing with the design-I am the one where the rubber meets the road.
