I don't understand why the service life is relevant here, unless ANA wasn't maintaining their planes properly which I doubt is the case given the reputation of this airline.

I included it because in theory it shows that the windshield was either overdue for replacement or it wasn't an original windshield, so it's not evidence of failure on Boeing's part in the initial manufacture of the plane. Admittedly, I don't know much about how maintenance works for these planes, so there could be something I'm missing.

> or it wasn't an original windshield

Put another way, it’s a recently-fabricated windshield. Which could be read as it being less resilient than the original.

That’s not how I’m reading it, absent further information. L

Or the opposite. Now people will become desensitized and assume it's just more clickbait.

I think you underestimate how many people hold a dim view of (nu)boeing

Or perhaps you overestimate how many people hold any view of Boeing at all.

This is one of those stories that wouldn't be noticed if not for the attention on anything Boeing related right now. Instead it's near the top of the front-page. This hyper selective attention is very bad. It leads to all kinds of wrong inference about the background frequency of events, because suddenly when under the microscope we notice all kinds of things that would have previously gone unnoticed.

True, but we see the same cycle frequently. Apple keyboards, Teslas and FSD, Apple antennas, Samsung phones catching fire, etc, all created an environment where tangential stories received elevated attention.

The plane in question was JA56AN [0], which according to PlaneSpotters.net was delivered in June 2009 [1]. Forbes [2] indicates that the service life of a fight deck window is ten years (it's not clear if that applies to the windshield as well as passenger windows)—if that's accurate, it's likely that this is completely unrelated to Boeing's significant manufacturing problems lately. Unfortunately for Boeing it doesn…

I would imagine the windshield is a recently manufactured replacement rather than the original article. There was a more recent 787 that suffered from a cracked windshield last December in London too.

The thing that really surprises me is that the regulatory bodies arent catching this stuff either, safety standards are not mutable.

On the other hand, the hyper focus on Boeing might result in some actual change instead of more of the same as before. Perhaps a little of the stick to contrast with the carrot?

Maybe, but if the perception is that they're going to get the stick no matter what they do, I'm not sure that creates much pressure or incentive to do the actually do the right thing.

Either way, I don't think it's a net positive for us to choose to be less correctly informed about an issue or encourage the same in others, even if it's in pursuit of an otherwise worthwhile goal.

They're fairly well known in europe after the MAX debacle, I don't know how it is stateside though.

It also happened in April 2022 on a Bombardier CRJ-700 [0] and in October 2020 on an Airbus A319 [1]. After the 2022 incident the local newspaper reported that it had happened more than three dozen times in the previous five years. If Boeing is disproportionately represented in those stats that's one thing, but so far I don't see any reason to believe they are.

When I see that the plane has been in service for 30 years and has a cracked windshield I think less about the age of the glass and more about the rigidity of the airframe. Seems that as a plane ages out it would tend to stress those types of parts more.

I measure societies by what they’re hysterical about. It’s the best measurement of character there is imo.

"... Flight 1182 was en route to Toyama airport but headed back to the Sapporo-New Chitose airport after the crack was found on the outermost of four layers of windows surrounding the cockpit, the spokesperson said ..." Hopefully people can tell routine maintenance issues from newsworthy improper design and implementation / manufacturing problems.

On HN? Never. This entire thread is proof of it.
