I posted on this having picked up the Tube video from another recent poster. I watched it in full and have just read the Washington Post link above. I feel the latter substantiates the old fears.
Not falling out of the sky? Okay, but what about the photo shots of airframes broken into three parts after survivable crashes? They make the point the breaks are reasonably clean around the circumference at the break points.
But be this as it may. If Boeing were setting out to make every part within three thou' tolerance, and hand-building them failed to come close to this, how could the Henry Ford philosophy be so readily abandoned when the parts turn up off-pattern?
What made me take an initial look was the Rosemont vane builds and rebuilds. In short, I'm starting to be spooked on the macro scale.
