When our test aircraft were being delivered, me and the other guys who work on the instro systems would ask, "Who was the asshole?" In other words, who took it upon themselves to be the person who made sure that things came together properly during buildup and checkout? The one aircraft we got where no one had stepped up for instrumentation and been the asshole has proven to be the most problematic of all the aircraft.

Maybe not the most elegant way to put it, but there you have it.
