“So Boeing produced a dynamically unstable airframe, the 737 Max. That is big strike No. 1. Boeing then tried to mask the 737’s dynamic instability with a software system. Big strike No. 2. Finally, the software relied on systems known for their propensity to fail (angle-of-attack indicators) and did not appear to include even rudimentary provisions to cross-check the outputs of the angle-of-attack sensor against other sensors, or even the other angle-of-attack sensor. Big strike No. 3.”
“None of the above should have passed muster. None of the above should have passed the “OK” pencil of the most junior engineering staff, much less a DER.”
“That’s not a big strike. That’s a political, social, economic, and technical sin.”
Medicynical note: Poor design, inadequate corrective measures= two crashes with hundreds dead.
Ignore the contrite humbleness, this mega corporation is selling an inherently unstable product.
