Could the accident be linked to the clarity of radio instructions? I saw a discussion suggesting the DH aircraft might have been unsure about the correct runway to use, C1 or C5. My aim isn't to critique the English proficiency of non-native speakers, especially those from non-Proto-Indo-European linguistic backgrounds. As a non-native English speaker myself, I understand the challenges. However, I found it trully ha…

There is a ton of static too, why is that still tolerated?

You say all this, yet waymo is demonstrably safer than the average driver. Uphill in snow maybe you’ll have to take the wheel, I’ll give you that.

How has this been demonstrated? They have certainly had their share of crashes already.

Over 50%, sure, but 50% of a very small number. How many deaths do you expect keeping passengers from being distracted at these times would prevent? (I expect if you compare that to the number of people inconvenienced by the rule it's a terrible trade off.)

The number of fatalities and injuries seems minuscule because it's normalised over distance traveled. This makes sense, because air travel is the only way to make voyages over this distance. But it also doesn't make sense for the same reason -- it's stupid to compare a 6000 mile holiday flight with a 6000 mile holiday road trip, because people don't routinely make those. You're still more likely to get injured on an…

Similar to the Jevons Paradox, where increases in energy efficiency often lead to greater overall consumption, as the higher efficiency broadens the scope of the activity.

Such a high comment to score ratio is typically due to political polarization, but there's nothing politically polarizing about this, so what's the deal here?

I think it's because of how dang merged multiple threads together.

The fact that everyone made it out alive from A350 is a great testament to the design. Insane.

Eh, not really. Any passenger plane design is supposed to be able to evacuate in 90 seconds. They had several minutes (at least) to get off that plane before the fire spread to the cabin.

Never really understood this "we can't enforce the rules because people routinely ignore the rules" attitude. This should be dead simple on an airplane, where the airline knows who each passenger is by seat. So have one flight attendant make one pass down the aisle warning everyone to put away their phones, then have another one follow a minute or so later just making note of which seats are still using their phones.…

Even when there was a rule that cell-phones were supposed to be turned off, studies showed that 20-25% of cell phones were still active (Possibly forgotten in pockets) - wasting time, energy, traveler patience, on something that was entirely theater (I don't believe there was ever a single incident associated with an active cell phone - which makes sense given the 10s of thousands per day that were powered on during…

I think the "no cellphones" rule is about minimizing distractions during critical phases of flight, not because a phone's radio is going to do damage to the aircraft. So a phone on but sitting in someone's bag is not the end of the world.

Definitely better links than Daily Mirror out there, avherald.com unfortunately overwhelmed, but in terms of discussion: - Crazy how well the carbon fiber A350 held up given that it seems to have landed pretty much directly on a Dash 8 (RIP Coast Guard team). Looks like trading long term flammability for initial rigidity lived up to the design intent. - Excellent evacuation job, especially as it looks like on some vi…

I don't see anywhere indicating they landed on top of the other plane

You seem really certain that passengers would be so wrapped up in their phones that they would be too distracted to promptly realize... there was a collision with another plane, causing their plane to split open and burst into flames. OK.

That 'prompt realization' takes actual time from an escape when it doesn't necessarily need to. I have no problem with the idea that humans can re-prioritize; but I do have a problem that people seem to think that the re-prioritization effort comes for free, instantly. We don't work that way as humans.

There's phone footage from inside the burning plane, so apparently your theories don't correspond with reality. Always quite annoying when that happens. Been the death of many a theory.

    comes for free, instantly
Here are the two biggest flaws in your thinking:

1. You seem to be assuming the alternative to "using one's phone during a landing" is some sort of highly aware ready state. In reality it's probably bored snoozing or half-snoozing. It's a red-eye flight after all.

2. You seem to be assuming that "evacuating a burning plane" is some kind of split-second thing, like a quicktime event in a video game. In reality, at least for this incident, there was a span of a significant number of seconds between "impact" and "plane slows down enough for emergency slides to extend and evacuation to begin." 30, maybe 60 seconds.... I'm not sure, but there was no real positive action for a passenger to take during that time. Shifting attention away from one's phone certainly has a nonzero time cost, but not remotely comparable to the time it took for the plane to come to a full stop.

Again, you're dealing in hypotheticals, while the actual reality of this incident (phones in use, orderly exit achieved, all lives saved) contradicts whatever it is you are imagining.
