>This is probably "just" a maintenance issue. >The Boeing 737-9 MAX rolled off the assembly line just two months ago, receiving its certification in November 2023, according to FAA record posted online. How does the maintenance crew fuck up a plane this badly in the span of two months?

Well, this is my field so let's calm down for a sec and dispense with the hyperbole. The plane itself is not "fucked"; my understanding is the aircraft landed safely and nobody was injured. The door/window that departed the aircraft is a serious incident that will be investigated. There will be a report produced that identifies the root cause(s). >How does the maintenance crew fuck up a plane this badly in the span of two months? Are you under the impression that aircraft maintenance works like car maintenance, where you just change the oil every so often? Lots and lots of things get removed and replaced on a regular basis. It's entirely possible somebody just didn't install the door properly after removing it for a routine inspection. It's a big deal and a serious incident but these things do happen from time to time, even at name-brand airlines. I'm all for lambasting Boeing but let's stop frothing at the mouth until we see the report.

  Frothing at the mouth is exactly what is called for here. A plane that loses a big chunk is indeed “fucked”, the only reason someone didn’t die is that that particular seat wasn’t occupied. There should have been many many redundant safety systems and procedures here with either didn’t exist or failed. People should be out for blood because there are obviously serious problems at both Boeing and the FAA. This was not a near miss, this was a 10 out of 10 failure of the kind which should never happen. The NTSB report will indeed show much but there is no reason to not demand congressional hearings and criminal investigations immediately. Everyone on that plane should start a class action suit against the FAA and Boeing immediately.

    I'm not standing by comments that go against the safety culture of aviation No, nobody should be "frothing at the mouth", that's an ignorant and unhelpful behaviour.

The seal failed and everything else worked. The masks, the procedures, the emergency landing.

      Aerospace was my field before tech was. Reliability is still my field. A door got sucked out of a plane in flight. That is not a matter of unavoidable human error but can only be the consequence of a concert of cascading failures of the type that should never happen which is why it’s a 10/10, if the flight had been full at least one passenger would have likely been sucked out. It is dumb luck that this did not happen. Your attitude of derating a disaster like this is a strong indicator of the type of problem in the industry. In the end if we don’t get executives resigning and major operating overhauls with the responsible entities, it will be a terrible miscarriage of justice.

        From the sound bites in these videos it seems sitting on the seat next to that empty seat was a child. I am thinking how each we fly my son always asks to sit next to the window.this accident was so close to having a fatality…

  This is a pretty arrogant reply. Whatever “field” you refer to, the problems at Boeing cut across disciplines and appear to go to systemic management problems. It’s not just issues engineering new systems. There have been well documented issues also with assembly and inspection. Boeing has a track record of recent quality problems at assembly time and even clashed with FAA on how to detect defects https://www.seattletimes.com/business/boeing-aerospace/faa-memo-reveals-more-boeing-787-manufacturing-defects-including-contamination-of-carbon-fiber-composites/ https://www.seattletimes.com/business/boeing-aerospace/faa-m...

    Yes, software engineers should take over airplane maintenance because their track record at safety is just sooooo much better, right? Airline industry has processes that work well and made flying ridiculously safe - there hasn't been a major plane crash in the whole of 2023! - maybe they know more about maintenance, accidents, investigations and corrective actions than a bunch of HN users?

      Members of the public should be encouraged to ask how this happened because they’re the ones who trust their lives to these planes. The airline industries in places where the public couldn’t ask questions did not make flying ridiculously safe.

        People can make a much better motivator by simply not flying. The general public really isn't particularly well suited for asking the right questions to get to the bottom of this, but they are well suited for not being customers if trust in the industry is lost.

  According to news reports, it wasn't a door though. It is said it was a window located at a place where a door could be installed as an option. If it's the case, I suppose there was not specific maintenance on this part of the aircraft. I do agree with you that proper investigation is required before jumping to any conclusion, plenty of factors (external or internal to boeing) can contribute into this type of incident.
