To be fair, the USA has higher rates of shooting down passenger planes in Iranian airspace, so we should probably chill and wait for actual investigations to be done.

Not any more.

Hey, you're doing that speculation thing again.

Then we should just close this thread since literally everything will be speculation at this point.

> I don't see the problem with speculation It's intellectually dishonest, particularly when baseless speculation is framed by an "it looks like." It crowds out fact-driven discussion. It's disrespectful and potentially hurtful. It could be mistaken for informed commentary, in which case it's misleading. (When I’ve done it, the first victim is myself.) And to top it off, it's useless. Totally useless. Nobody walks awa…

You stop because what you are doing is typing a lot of words without saying anything useful. You’re being a bully.

Observations are useful. Even mistaken ones.

Saying "It looks like..." is stating a fact. What else is someone supposed to say if that’s what it looks like to them?

It doesn't crowd out "fact-driven discussion".

It's not disrespectful or potentially harmful.

Anything could be mistaken, even empirical evidence. Even what you think is a fact...can be wrong.

> And to top it off, it's useless. Totally useless. Nobody walks away with a deeper understanding. No new perspectives. Just screaming into a void.

That's you. You're being ridiculous. You're over-reacting. You haven't produced any evidence to backup your opinion that speculation is harmful or crowds out your so-called "fact-driven" discussion, or that what is said here on HN has any effect whatsoever on anything going on with this story. Just stop it.

> In a sign of the potential difficulties facing crash investigators, the head of Iran's civil aviation organisation was quoted as saying the Ukrainian plane's black box would not be handed over, either to Boeing or the Americans.

Would they hand it over to Ukraine who could then hand it over to Boeing? If not, how likely is it the investigation will be reliable?

But it was built 3 years ago. Does proper engineering prevent future failures if the assembly process becomes flawed at a later time? For example using cheaper materials, ignoring cracks, not properly training new employees etc.

...stray tools forgotten in the airplane after assembly, metal shavings close to cables... yeah, I read those articles too. However, the fact that the Iranian authorities already concluded that the cause was "engine failure for technical reasons" seems a bit suspicious.

Are stray bullets or missiles considered technical enough?

Like Tom Cruise. Despise that guy. Not but really, why has "bad actors" taken off as the pejorative for offenders these days?

"to act" has also other meanings than just be on stage or in front of a camera. Similary, an "actor" has also other meanings than just an individual being on stage or in front of a camera.

A three year old Boeing 737-800, which does not have any known safety issues. It feels deeply implausible that this airplane would simply crash due to mechanical issues two minutes after taking off from Tehran just hours after Iran retaliated against the United States's assassination of General Qassem Soleimani, but then again there was also an earthquake in Iran just a few hours ago, so I guess maybe these things ju…

>>but then again there was also an earthquake in Iran just a few hours ago Noob question, what are the odds they were testing a nuclear weapon, and how would a foreign agency go about finding if they indeed did a test?

Nuclear weapon detonations (particularly when tested underground, which is done mostly to avoid atmospheric contamination) can be identified through seismic arrays. The system is pretty reliable, and beyond the obvious task of distinguishing between natural and human causes, it is even capable of detecting the approximate origin. I remember reading an article about how even civilian arrays were capable of identifying tests in North Korea, and distinguishing between detonations, and the following cavity collapses.

The investigation is on Iranian soil. There is no access to the FAA or similar agencies. Iran would have every reason to want to cover up an erroneous missile launch. In Ukraine, there was a cooperative effort to investigate the crash, and it was found to be a Russian missile.

Yeah, that's what I was thinking as well. But others are saying it is possible to track missiles with systems other countries have. So, hopefully we will have some answer.

Not possible for a low altitude SAM that would be used for something like that, unlike MH17 at much higher altitude.

To track it you'd have to be really close. Like next neighborhood or so.

There are suspicious smaller holes near portholes of the aircraft debris. Could it be shrapnel? This is the basic principle of how anti-air systems damage the aircraft engines. The smaller holes also might be caused by explosion during the ground impact though. This is going to be the hell of an investigation given the current tensions in the region.

Multiple small holes in the aircraft shell is generally not caused by hitting the ground, and is indicative of a missile strike.

In the case of a missile strike, wouldn't the aircraft disintegrate in the air?

Pilot should be able to communicate even if engine is on fire (especially then). Transponder doesn't suddenly stop working if your engine erupts in flames.

Aviate, navigate, communicate. They would have been rather occupied with the first two.

To be fair, communication is different from ADS-B transmissions, which end abruptly at the flight's maximum speed and altitude: https://www.flightradar24.com/data/flights/ps752#23732569

Note the surnames. I wonder how many of these people were in the streets of Tehran just hours before, chanting "Death to America?"

And now I'm supposed to feel sympathy for them? Please.
