Engineers and pilots usually share the same passionate common denominator when dealing with helicopters. It means that their relationship is more like of a love and hate type. Now, maintenance is becoming more and more computerized and numeric with captors everywhere but I like to see when they lay a palm on a tail boom to detect weird vibrations listen for noises or smell for some overheat. Even for the new ones, time and experience turn them into craftmen that cannot be replaced with a snap of fingers.
