Shall we continue to get killed because it is easier to produce aircraft with a design from 1950s?
At a rate of about 700 deaths for about 3 billion passengers (both yearly averages). That's less than 0.3 ppm.
What industry would completely redesign itself and increase its costs by even 1% (this would probably be more like 20% plus the fix cost of the changes) to reduce its failure rate to below the current 0.3ppm (and then again, not necessarily to zero, as the last few year's crashed are not related to the kind where this system would help)?
This is merely interesting as an exercise for students. Studying concepts not viable in the industry is a laudable, but idiosyncratic purpose of academia; a bit like Smalltalk for instance.
I'm also not surprised it was made into an autoplaying video idiots share on Facebook.
