Why don't EASA, the FAA, Boeing and other regulatory bodies know what some of you PPRuNers know?
The comments here are because, in the 21st century, no one trusts big business or government.
I recall an eminent Austrian mathematician (born 1919) saying: "In my country, we never believe anything until it is categorically denied by the government."
If this was the 1980s or 1990s, more people would believe Boeing and more people would expect Boeing to have resolved this during testing.
The failure appears to have come about because ground crews had not been fully trained in how to handle the a/c and THAT means that Boeing did not ground test enough - in such a way as to mimic operations.
It's all well and good to expect flight crew to run the ship pretty much as trained but ground crew have been handling most a/c the same way for years. If they have to change their process, then more attention was needed at the planning and testing stages.
I sit to be corrected.
