content: Very bizarre that the flightradar data stops abruptly at 8000ft and no further comms from the captain. Surely an engine failure or even an onboard fire would not lead to that system failing immediately.https://www.flightradar24.com/data/flights/ps752#23732569

content: Quote from: tom66 on January 09, 2020, 01:55:43 pmIt also doesn't show the attempt to return back to the airport that was reported today. Presumably FR24 data is based on the transponder only but ATC would have continued to track it as a passive reflector, especially as the eye witness reports are that it came down in one piece. <wild interweb speculation>Loss of the transponder and no mayday might suggest some kind of wide-ranging electrical failure.</wild interweb speculation>

content: One could see a single engine uncontained fire as damaging hydraulics and eventually leading the aircraft to crash but from what I remember there are multiple redundant power buses.You have one generator for each engine plus an APU (and the procedure in the case of an engine fire is usually to start the APU as a backup)Then you have 28VDC buses (three: two primary and one emergency); at least two of which have backup batteriesThen you have 115VAC buses, which can be inverted from the 28VDC supplies or provided from the generators.I don't think the 737-800 has a RAT, but cable flight controls which mean that it should still be possible to actuate flight controls in the case of total electrical power loss.So the mystery is why did the transponder stop without the aircraft appearing in distress beforehand?A single failure or fire should not lead to the avionics losing power. The Iranians are claiming the black boxes are partially damaged and some data is lost. I think this might be a misunderstanding as the flash memory should be intact even from that crash, but it is likely that as power was lost the black boxes lost power too. This has happened in cases of on-board fire in the past.However such a catastrophic loss of power would surely require the avionics bay to be compromised as a result of fire or explosion, as there are numerous circuit breakers that should mean even if one engine was completely destroyed that the FADEC and pump, etc. supplies, should be isolated shortly thereafter.There is always the option of missile impact (mistaken) as in the case of MH17, but no one is claiming that right now. You would think that if there was evidence then accusations would begin to fly here.Very strange.

content: We may never know what happened. The questions to have answered would be did they loose radar contact? Did they also loose transponder. Was there any change in transponder code? If they had a catastrophic engine failure with loss of power was the APU not functioning. At 8000 feet there are a lot of things and lots of time to get even a completely unpowered aircraft under control even at night. Pleanty of time to get a transponder (which on a NG should have battery power) to 7700 and let most of the countries in the region know there is an emergency occurring. At 8000 they are under climb power. If there was an uncontrolled blade release or other shroud failure as with the southwest flight some years back the damage pattern is not as excessive as to cause this sort of crash. Evidently this was a well trained experienced crew as well. I hate to say it but the most plausible scenario here is that the thing was shot down. Possibly a nervous anti aircraft missile controller who knew they were firing missiles into Iraq at that time imagining a retaliation strike or something. Planes just don’t fall out of the sky that alight. The witness footage showed a very bright glow before impact. That does not happen with engine failure.

content: The current Boing and FAA investigations may be reason enough not to trust the FAA / NTSB too much. So I can understand that they want too look at the flight recorders independently. They later may still share the data with the NTSB and Boing.So far is looks much like technical failure, that may have taken out communications and transponders. The investigation may take a few more weeks to give more details, especially if the data are not directly going to Boing.I don't think they have to ground the older 737s too.

content: Yeah. My first reaction to this was not even "oh it's suspicious", it was just "oh no, not a 737 crash again..."And until a serious investigation is duly conducted without opacity, we won't know the cause. But it certainly isn't the right time for Boeing to have to go through this (even if it ends up being proven that the plane itself is absolutely not a cause, which may be very hard to prove here given the context...)

Out of these seven, I am aware of two they were not born in Canada and had therefore at least dual citizenship.I could be wrong, but I think none of these 63 Canadians were "Canadian-born citizen". Therefore, what about the citizenship from the country from where they were born?But, this does not make their tragic death less horrific.

It would be no surprise if the Russians (military and economic allies with Iran) were part of a plot to shoot the plane down, considering how many Ukrainians were on board and that it happened straight after Trump ordered Soleimani's execution. There were no Russians on board. But maybe it was just coincidence and bad timing by a band of Iranian meatheads.

Start in English at 1:48But now here we have surprise surprise FOX (tom66 close your eyes FOX to right wing) saying Iran didnt shoot down the 737!And here we have another longer video of the flight who show the event before it caught fire, it seamsthe big boomy fire of the suggested SAM shown in prior video from another angle came at the very end.And an chopper Arial video on crash site. It also seams the claim Iranians bulldozing the site west MSM vomited out earlier is just the regular MSM BS! So far seams the only ones who keep their head cool is the Iranians while west is trying something else.

content: This thread illustrates why there is so much conflict in the world. Much willingness to pick and choose reports which are true. While at the same time saying that all press is false and propaganda. Much speculation going beyond even the questioned "facts".Here are the things I believe to be true.1. There are at least two groups that have a very good idea of what happened. Elements of the Iranian government and the US government. The Iranians based on their access to all of the direct evidence. The US based on various electronic and optical surveillance activities which I am sure are going on at high pitch through the area.2. This truth is propagating through the rest of the respective governments, through both official and unofficial paths.3. The various factions in each country are figuring out how best to spin the information for the benefit of both their faction and their country.4. Something like the truth will eventually come out. Probably in the not very distant future, but maybe not for months or years.If I were a betting man I would say that an Irani air defense unit was at high alert and waiting for a strong US response to the missile launch (maybe just aware that their country had threatening retaliation and without being actually aware of the missile launches) and made a mistake. Whether the mistake was aided by the presence of US aircraft in the area or not probably isn't as important as just the anxiety, lack of knowledge of what is really happening (fog of war) and so on. But that is pure speculation aided by a few photographs and tapes that have already leaked out.

content: If this was an accidental missile launch (which seems to be the case), I wonder if it was the same system that the Russians used in the MH17 incident. Do the Russians sell these systems to Iran? Perhaps the system is flawed or needs better training to use properly. Otherwise you could attribute it to rising tensions causing knee jerk reactions. We still don't know, so no sense speculating anything.Either way, a tragic loss of life. We in Canada are getting a lot of news about this lately and our Prime Minister is now involved as it was apparently a Canadian-bound flight (it was one of the few options for Canadians travelling to Iran). 138 passengers bound for Canada, 63 of then Canadian citizens, many young students visiting family over the holidays. Very unfortunate and sad.
