  • Yeh it is.
    Proving that a scientific theory is wrong means we don’t understand enough about the thing. And we know we need to look at other theories about the thing.
    Proving things wrong as well as failed hypothesis is as important (even if it is disappointing) as proving things correct and successful hypothesis. It rules the theory out, and guides further scientific study.
    With published papers, other scientists can hopefully see what the publishing scientists missed.
    Scientists can also repeat experiments of successful papers to confirm the papers conclusion, and perhaps even make further observations that can support further studies.






  • Your threat assessment is way off.
    So, you import a phone. What sim do you use? Where do you use it? When do you use it? Who do you contact with it?
    All of that is more valuable and easier to get for the police than some sort of modification of firmware or platform as it passes through customs.
    If in doubt, flash your own firmware.

    If this is actually a threat assessment to you, asking on Lemmy is the wrong place. You need people with the same experience that an entire country has at their disposal.

    If it’s a concern as opposed to an actual threat, buy some 2nd hand phones from random places and buy some prepaid sims (ideally via smurfs or black market means). And be aware of how you use them



  • Autopilot crashes?
    You mean MCAS (Maneuvering Characteristics Augmentation System)?
    It’s not autopilot. It’s worse than that.

    Due to the larger engines needing to be mounted in a different place, the flight characteristics changed between previous gen 737s and the new 737 MAX.

    The characteristic change would mean it needs different certification from air authorities and existing 737 pilots would require recertification to be able to fly the new 737 MAX (which is supposed to be just an updated model).
    All very expensive for what should be merely an upgraded model.

    To avoid this, Boeing used software to change the characteristics in order to bring it inline with previous 737s and the existing certifications.
    And as it was just an augmentation system, it was deemed high risk but not critical risk. As such, it didn’t require full redundancy, didn’t require Quick Reference Handbook entries incase of issues/errors, and didn’t require training.
    In fact, pilots had no idea it existed, what it could do or how it worked.

    Which means when it had an issue and caused extreme pitch down due to faulty sensor readings, the pilots had literally no idea what was happening as they were trying to stop the plane from accumulating pitch down every 5 seconds.

    And then Boeing tried to fuck with the narrative. I think they also didn’t tell pilots about MCAS until after the Ethiopian Airlines crash (the 2nd caused by MCAS), but I’m not 100% sure on the timeline.

    Boeing has had a stream of QA issues, the way MCAS was handled was idiotic, they are a shitty company.

    But I have no issues flying in a Boeing.
    I don’t like or trust the company, but I trust the air authorities. And most of all, I trust the pilots.





  • That’s a great rundown with decent logic & examples behind each point.

    I think the biggest point is the takeoff weight.

    If the impact/evac/safety aspects can be addressed, the only way I can see it working is to add a “cattle class” that’s like $10 cheaper than current economy and has something like 40 “seats”.
    Then increase the price of what is currently economy class by $10-20.
    You lose $400 because of the new cheaper class, but gain $1,200 to $2,400 by increasing the price of economy (considering a 160 seat plane, and convert 40 seats to standing). So, net gain $800-2000. Let’s you advertise new cheaper fares, and the price increase isn’t hugely egregious when the 40 seats sell out instantly.
    I guess it doesn’t work on less busy flights if only the 40 cheap seats sell




  • You are probably underestimating your abilities.
    People that worry about overestimating their skills mostly underestimate their skills.

    If someone says they are “good” at something, I take it to mean competency and some enthusiasm.
    They might make a mistake, but they won’t (or at least will rarely) make it twice.
    They know how to find the solution to something within that domain of knowledge. It might not be the best solution, but it will be a solution that works.
    They are also aware of what they don’t know in within the domain. So, they can do C++ but know they can’t do embedded programming. Or they can do C#, but know they can’t do game dev.

    And I would take them at their word for that, until they prove otherwise.
    If they are below where they claim their skill is, I would try to help them learn (unless they show no interest in improving).
    If they are above where they claim, I would tell them this.

    It’s always hard to judge our own skills.
