I tend to agree with FE Hoppy.
A lot of speculation to whether various systems failed or not. All ivery nteresting, but not plausible.
The flaps were not correctly set - propably not set at all. A mistake that was not arrested by the config warning.
The likelyhood of a flap fault and a config warning, that did not work is marginal.
It will propably turn out to be crew error - as the Detroit accident.
I think, we should focus on how to avoid these errors. Put focus on the ever more stressfull environment, we work in. Sub Part Q, pressure from the company etc.
