I recall comments from an LTU captain some years ago in CMB, about the MD-11.
He mentioned that behind all the fancy glass displays was a multitude of electrical problems, and ....'the eleven hour flight from DUS was a veritable christmas tree of lights, red lights, yellow lights, we have them all indicating possible failures of one sort or another.'
A year later brought forth a completely different comment from the same LTU captain however, now it was...'the christmas tree of failure lights are gone, she flies like a dream, we certainly like her now, not quite as nice as the TriStar I flew before, you understand, but still very nice'
