> For the past several months and in the aftermath of Lion Air Flight 610, Boeing has been developing a flight control software enhancement for the 737 MAX, designed to make an already safe aircraft even safer. This includes updates to the Maneuvering Characteristics Augmentation System (MCAS) flight control law, pilot displays, operation manuals and crew training. The enhanced flight control law incorporates angle of attack (AOA) inputs, limits stabilizer trim commands in response to an erroneous angle of attack reading, and provides a limit to the stabilizer command in order to retain elevator authority.

That they're pushing a software patch for this would seem to indicate there's something in the actual plane worth fixing.

It does seem to be partly operator error, and that operator error is Boeing's fault because they did things in a way that maximized the chance of it occurring.

If it turns out that the pilots actually need some training to reliably fly the 737 MAX, there could be some nasty consequences for Boeing.

> At an airshow in 1952, a supersonic fighter disintegrated in the air causing the death of both crew and 29 spectators (Staff, 1952). Over 100,000 people witnessed the accident. A public appeal was put out for witness accounts and photographs to help solve the mystery, resulting in several thousand letters being collected. Rivas and Bullen (2008) found “many of the accounts are touchingly detailed and well intentioned, but the whole of the vast mail was of little use” (p. 186). The vital clue that led to determination of probable cause was supplied by a cine film. The in-flight breakup happened in less than a second, and almost all the eyewitnesses, including experienced pilots, gave grossly inaccurate accounts when compared to the film record.

I'm not 100% certain however, if someone can say if I'm wrong or not, he is welcome ^^.
