The mainstream media in Europe only just now found out about it?
It was reported over two or three weeks ago in a long article in the (US) Wall Street Journal. It featured a design engineer and his problems with the production of certain plastic parts, and his responsibility for a specific amount of weight reduction. It seems that the new production process is a challenge to the factory workers.
Weight problem? How about an evacuation problem combined with a collapsed main/nose gear (with real passengers instead of well-rehearsed Airbus staff with family members...), and/or in very high winds? High winds and wet weather contribute to many accidents. Many more people would ride in the upper deck than on a 744.
There can be no connection between this topic and the other one on Rumours and News, by Dagger Dirk: "It doesn't pay to be a whistleblower...".
