Design problem? Or Mission problem?
If the FAA is to "encourage aerospace travel" and provide for the highest level of safety, we have the problem to hand, and it is not pretty....
The salesman also oversees safety? Hello?
Part of the globalisation of aero construction (design?), other than fracturing single site assembly, is to dilute and diminish ultimate responsibility, and not just the financials.
The definition of good design is to simplify to the point nothing is left that is not crucial. Scattering critical task at the altar of "sharing" is risky, if not downright dangerous......the incest of discrete disciplines is the problem.
This applies to the blending of newish technology with "marketing"....to include manufacture, oversight, and reliability (safety).
