Anon Boeing engineer reveals why the 737 door blew off

Do we need another duplicate posting? First post was 12 hours ago[0] (469 points, 362 comments), and a dupe was 3 hours ago (116 points, 7 remaining comments - was merged into the first)<p>[0]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39102021">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=39102021</a>

If this is true, it is impressive the door stayed attached to the plane as long as it did. If they really forgot to install all of the bolts intended to hold it in place, I would have expected to to fail much sooner.

Can someone contextualize this link? On its face, I&#x27;m seeing the equivalent of someone posting a big-tech expose on this HN, only for PG himself to reply saying &quot;pls email me at pg@ycombinator.com&quot;; and then another reply suggesting how to avoid being outed just like Journalist X&#x27;s source was, only for Journalist X to reply with &quot;if you know how my source was outed, please text me at &lt;cell&gt;&quot;<p>Like what is this site even?

Related question: I&#x27;ve seen news reports that the plane had experienced three recent pressurization issues (cabin pressure warnings). Does anyone know what kind of warning this was? Was it:<p>- too low pressure, meaning that the door might have been leaking before it blew out.<p>- too high pressure, meaning that the door had extra force on it.

In my opinion, the fact that this airplane isn&#x27;t legally an airplane yet, just a collection of parts, is part of the problem. Boeing and Spirit should be criminally liable for mismanaged production, or at the very least have their production certificate for the type revoked.

American airline companies should just buy Airbus planes until Boeing gets its act together.

What a mess

Ah, so the mystery is solved: the doors were <i>never</i> bolted. Inspections done in Renton caught this in 99% of cases but nobody thought to follow the defect to source and get it fixed there. Classic case of &quot;you can&#x27;t inspect-in quality&quot;.

It&#x27;s not very typical, I&#x27;d like to make that point.

I don&#x27;t trust bike shops to take care of my mountain bike, I don&#x27;t want to break my neck because of some mechanic. That&#x27;s why I do my own service.<p>I don&#x27;t fly anymore but I guess next time I&#x27;m going to have to build my own aircraft.
