No. Most airliners CANNOT dump fuel. This capability is limited to long range wide bodies, like this 787. Neither the 737 nor the A320, which constitute the majority of commercial air traffic, can dump fuel. Fuel dumping is normally performed at an altitude where it should be able to evaporate before hitting the ground, and it takes a long time, maybe 15 minutes to get from full fuel to maximum landing weight. Using…

A more dispersed fire. The amount of fuel isn't changed by dumping.

No. I said a larger fire, and I meant it. The fuel on the aircraft is not the only thing feeding the post-crash fire. Dousing the entire flight path with an accelerant would have resulted in many many buildings being on fire, instead of just a few of them.

"No correlation between non-functional displays on passenger seats & possible engine failures etc." No. No no no. This is wrong, mistaken thinking. A minimum standard of operations and attention to detail must be adhered to for high consequence / life critical endeavors and that behavior (culture?) must be enforced at all levels throughout the operation . Ignore this heuristic at your peril - as either a consumer of…

It’s wildly unrealistic to expect maintenance to fix 100.0% of issues, and to fix them immediately at that. There’s a balance to be struck with on-time performance that will naturally prioritize safety critical maintenance while postponing cosmetic repairs until they can be performed without schedule pressure.

Eventually it all folds into one management org, that is the whole issue.

I wouldn't expect two parallel cultures in a org, one for safety, one for entertainment systems.

Most airplanes can dump fuel, but it's not an immediate thing, so not really applicable here (and obviously doing it over a city is to be avoided as well). It's primarily needed for weight management in planes that can take off heavier than they can safely land. I.e. if the plane had enough control to abort the flight and return to the airport, then it might have been appropriate.

Didn't Sully dump fuel before landing in the Hudson, thereby increasing the buoyancy of the plane?

The Economist? I just unsubscribed from the digital edition. A neoliberal and globalization bias in overall tone.

They've always been upfront about their bias, in no way are they trying to hide it. Way back when I was in college 20 years ago they ran a very funny article poking fun at all the PhD's doing "deconstruction" on The Economist. Like super post-modernist fluff. I could tell the writer had a great time responding to it. Their punchline: "so there you have it - a newspaper to make you feel good about tomorrow by promotin…

Haha, that's so funny.

Pro tip from an absolute rando: don’t bother with any source of breaking news. Read a weekly paper that summarises the important stuff. If something is truly pressing, you’ll hear about it from friends or coworkers.

Pro tip from another rando: If you hear about it from friends or coworkers, don't assume it's pressing. It might just be sensational and of course they repeat it, just like they'd send on a chain letter/email etc. back in the day. Form your own opinion, based on multiple source plus your own judgement.

> Form your own opinion, based on multiple source plus your own judgement

I think the essence of these statements is less that you should literally listen to whatever distilled amount of world news your coworkers are talking about and take it as fact, but that if it's remotely necessary for you to even be aware of, let alone have an opinion about, it'll present itself somehow in real life. After that, if it qualifies as relevant to your life, then go about searching for more info, but a vast majority of anything you could hear or read about or watch probably doesn't qualify.

Government policy, sure, if you need to respond to or act on it somehow. Conflict in the middle east? Sure, if you or someone you know has ties there. But again you'll probably just hear about it because it's directly impactful, or you can monitor specifically for those updates using narrow channels.

My point is more that non-functional infotainment on one single flight is just simply nowhere near enough data to judge a whole organization.

From the television era: Don't watch news channels; important news will be on all the channels.

I'm not convinced there is really any important news.

There's a spectacularly untimely take...

Gentle tip from a lifelong aviation enthusiast: wait one week before reading on causation. Exposing yourself to first-week speculation isn’t just unproductive, it’s often counterproductive since the actual findings can rhyme with the false speculation closely enough that you wind up muddling the two in your mind.

I'm fairly sure a fraction of the "techbro" community has already decided its due to Indian programmers at Boeing, or Indian managers at AI, or some other Indian voodoo in India.

Economist for me. I don't know of any other sources that can reach the same level.

I had been a Economist subscriber for almost 20 years. But then gradually I realized that their reporting on some issues are extremely biased and they conveniently skip reporting some facts to match their intended narrative and lead the reader to distorted conclusions. So I would assume they would be doing the same with other topics as well. I did not renew my subscription.

Could you give some examples?

We know that twin-engined airliners can successfully take off on one engine. It happens from time to time. E.g. https://www.nbcnews.com/news/amp/rcna179267

At no point did I claim that multiple engine aircraft cannot complete a take off on a single engine. The statement I made: > Aircraft can land (in right circumstances) by gliding in sans power .. the same cannot be said for take offs. is about having _ no _ thrust power during take off. The other statement I made acknowledged that test pilots in planned and scheduled clear weather conditions often test aircraft with…

You did challenge the claim that they could complete take off on a single engine: https://news.ycombinator.com/item?id=44256705
