This is about corporate greed and the GOP's seemingly insatiable need to cater to corporate interests , literally, at all cost.
This travesty is due to Boeing being caught short by a competitor, Airbus, in the drive to produce the next generation airbus for the world. Rather than spend the five years and billions in developing a new airframe Boeing jerry build a design from the old 737 and hung too big engines too low on the fuselage which created instability. But. to compound the chances of a disaster they insisted on and got reduced FAA regulations and, get this, allowed Boeing to conduct its own safety certifications and safety approvals. Fox in henhouse when corporate profits and executive bonuses were on the line.
This is a failure of both Boeing and Federal safety regulation. This plane will never fly safely no matter how many bells and whistles and hi tech gadgets you hang on it. Put a fork in it and move on lest more die needlessly.
