Jesus fucking christ they are doing this on a plane that we don’t have any industry-wide long-term real-world durability data on because that’s the first fully composite airliner ever manufactured. Nobody really knows what long-term high-hour failure modes will look like.

We can simulate and guess, but when they cut corners like that, it introduces all kinds of horrifying possibilities involving cascading structural failures. Like, maybe the bonding surfaces between the fuselage and wing box starts to delaminate and, oh, I don’t know, the wing separates from the fuselage or something like that.

Perhaps I’m being sensationalist - I don’t know all the ins and outs of their manufacturing process. But I’m going to remain pretty fucking concerned until Boeing can conclusively prove it’s either not a problem, or that it can be correctly repaired back to original specs.
