Not to mention Boeing, and more importantly, Rolls Royce´s complicity in all of this. These engines are now over 25 years old and they are not a whole lot better than the day they were built, design-wise, and a whole lot worse than when they were built due to wear and tear. While not excusing DHL for their cavalier approach to the issue re: the oil overfillings and allowing the situation to develop whereby spares and maintenance have been allowed to dip to the current farce, is it not largely the responsibility of the manufacturer to ensure the product was properly built in the first place?
