So in summary, Boeings break down like MacDonnells[1], but it’s not Boeing’s fault, it’s the fault of the entire ecosystem, but not Boeing, just everyone involved with Boeing, we get it. Entire denial of ownership of problems should be patented as a business model. So that no other manufacturer can copy it for 20 years.
[1] McDonnell planes were known for falling apart, doors flying in the air, lengthened planes which didn’t adapt the airframe for the new length, or just pieces falling off. Remember the Concorde getting pierced in the fuel tanks by a metal frame dropped on the airstrip by the previous plane and crashing into a hotel? Yup, it was a piece that fell off a McDonnell.
Their point is that cracked windshields are neither uncommon nor (typically) dangerous. They happen regularly across all manufacturers and have redundancy in place to make sure they don't hurt anyone.
Boeing has a lot of problems, more so than other manufacturers, but this isn't a good example.
no, in summary, airframers all contract out their windshields to the same few specialists, whose replacements are routinely retrofitted without OEM involvement, and cracks developing in a windshield designed to be resilient to a crack developing in one of the layers is not an unexpected phenomenon.
(And fwiw the bit that fell off the DC-10 that the unlawfully overloaded Concorde ran over was an engine part on a GE engine incorrectly retrofitted [twice] by Bedek and Continental respectively shortly before it detached, so it'd be difficult to imagine anything that had less to do with the half of the airframe OEM that didn't design the the non-engine parts that didn't fall off over quarter of a century earlier. Might as well get angry at Bill Gates for air traffic control failures)
