"With regard to electrical wiring - you probably have not been near an airliner when it is undergoing a D-check, have you?".
Actually my friend, not only have I been near an aircraft undergoing a D-check, I have actually done them, being an ex E & I ame. Just as the reason for the Aloha airlines accident was found so will others be found. As aircraft age, problems develop, new areas of concern are found.
