Re: <nettime> rage against the machine


In case you missed, all narratives about pilots not being trained/informed were red herrings. It looks like it was an attempt to deflect blame on humans (either those that were supposed to inform pilots or those that were supposed to establish proper training procedures - from Boeing and individual airlines), in order to save the sanctity of AI deity. It all turned to be bs.

Pilots did everything Boeing deemed required to regain control:

As the jet began nose diving, the pilots "repeatedly" performed all emergency procedures provided by Boeing, the manufacturer, but they "were not able to control the aircraft,"
...
According to the sources, the pilots did not try to electronically pull the nose of the plane up before following Boeing's emergency procedures of disengaging power to the horizontal stabilizer on the rear of the aircraft. One source told ABC News they manually attempted to bring the nose of the plane back up by using the trim wheel. Soon after, the pilots restored power to the horizontal stabilizer.

With power restored, the MCAS was re-engaged, the sources said, and the pilots were unable to regain control before the crash.

So it's much worse than it looked like. Boeing designed automated machine controls which they (Boeing) did not understand. It had modes of operation unknown to its designers. This is inevitable - I'll repeat: INEVITABLE - when you have more than few thousands lines of code. There are no testing procedures to save you from this. There are only testing procedures to cover up your ass with legal compliance requirements.

This placement of complex automated control loops everywhere is starting to look like putting small nuclear reactors in homes, cars, schools, offices, etc., because it's cheaper than distributing gas and electricity, and hoping that sh*t won't happen. No, I'm wrong: they know that the sh*t will happen, but the calculation is that even after insurance pay-out and ephemeral PR damage it is still cheaper. The two recent disasters were allowed calculated risks.
