I'd like to know where the FAA is during the congressional hearing on the 737 Max. Boeing built it but the FAA had to certify it before it could carry passengers or even be sold. If they have no responsibility then exactly what is their purpose and why are we paying them?
Part of what Boeing did was underequip the plane with a single (ONE) pitch sensor, specifically so that it (Boeing) could
circumvent the FAA regs -- a more adequately comprehensive multi-sensor system would have required extra training under FAA regs, and Boeing didn't want that delay because they were in such a hurry for Profit.
The whole freaking plane was badly designed by hanging too-big engines where they would throw the balance off and kick in this whole pitch problem, which then had to be compensated by the ultra-super-secret software nobody knew about, wasn't trained on and couldn't be controlled --- rather than designing the plane to accommodate the engines, from the ground up, again in a mad dash for profit. This came back to bite them.
