Ever read Michael Crichton's "Airframe" It could have been written about this very thing. Right down to an uncommanded flaps deployment.

They wont offend a potential customer. If there is pilot error they will gloss over it.
You see how they buried the additional training in that statement? Why? Why mention pilots at all unless pilot error was part of the problem? And if it was even remotely possible why arent they making that reason one and not software? I believe that based on that statement that there was software and pilot error.

To ensure unintended MCAS activation will not occur again, Boeing has developed and is planning to release a software update to MCAS and an associated comprehensive pilot training and supplementary education program for the 737 MAX. ...
See the part about comprehensive pilot training?
(bold mine)
Is it possible that the system was disabled?

1. Shouldn't the sensors have always compared more than one input before making un-commanded flight control inputs? There's two of the best sensors of all sitting right on the flight deck, they're called the pilots. Why not two sensor comparisons before taking control away from those two pilots?
Used to work in aircraft design (military not civilian but was headhunted by Boeing). I've never heard of a sensor not having a back up device or secondary measurement reading to avoid catastrophic incidents such as these (not only in planes, basic principle of design is to have a failsafe). Cockpit isn't my forte but a lack of a manual reset or override in the event of system malfunction seems equally bizarre.
Surprised they're not going over the whole design with a fine toothcomb, basic errors like that should never even occur in design process let alone make it to the end product.
