In the dailymail article? I don't see any parts with Cyrillic labels. In fact, all I see in Russian is satellite photos. Which photo number?

Do any sat photos label what sections of the airplane are present at each of the blue boxes? Just looking to see where the tail section ended up. My understanding is that it landed behind the fuselage and wings by a good distance.

AP says satellites "...detected heat around a Russian passenger jet before it crashed..."
Any guesses on how sensitive those instruments are? How much heat is required before it can be detected? Dumping a cabin volume of 70deg air into -xx deg (whatever it is at the flight levels), would that be detected? Or would it detect heat off the engines if their orientation changed and pointed exhaust at the sats?
If the pressure vessel blows there is a good chance of rupturing something in the fuel system like a tank, atomizes in the airstream and ignited by the engines.
Yeah - that's possible, I guess, an Airbus thermobaric bomb.
That would be a result of the breakup, and not the cause.
I would be cautious, in some other reports the word "before" is missing and we simply have that it detected a heat spike at the time of the crash. I can imagine an aircraft hitting ground and exploding would also cause a heat event.AP says satellites "...detected heat around a Russian passenger jet before it crashed..."
I used to drive those satellites. The problem is, saying "a satellite detected heat" doesn't tell us much.AP says satellites "...detected heat around a Russian passenger jet before it crashed..."

The thing that gets me about the explosion-in-flight theory is, how did no one else see it? Yes, it was over the desert, but the plane would have been in line-of-sight for a number of other aircraft. No one's coming forward to report seeing the flash?

The Russian-language media report that so far no traces of explosives have been found on the wreckage.

The Early Warning satellites I used to fly (Defense Support Program) operate differently from a system designed for intelligence purposes. We scanned the Earth continuously, but the scan rate was slow enough that the time of first detection wouldn't be that precise. If the ground impact didn't occur for another ~30 after the time of detection, that could indicate an air burst.
Threshold wise...well, the early warning system are designed to detect rockets being launched, and for the most part, the thresholds don't have to be that low. It's possible the regional thresholds are set low due to the volatility in the Mideast, but there are vehicle thresholds as well that are not generally touched unless a detection cell goes bad. These systems do not produce images; only cells which detect events over thresholds are presented for operator display.
That said, yes, we did detect some aircraft crashes. I remember seeing the fire after the DC-10 crash in Chicago, but this sort of thing was relatively rare. Mount St. Helens was fun, though. We saw the sun reflecting on the ash cloud...and, of course, the unnamed satellite might have seen the sun reflecting off some sort of fuel plume.
The problem is, these events are still relatively low heat (in comparison to what the satellites normally look for) and there's no automatic detection for stationary events. One can re-run the satellite data with lower ground thresholds, but they still are limited by the onboard thresholds.
Mind you, this knowledge is 38 years old. Things may have changed.
Intelligence sensors no doubt operate differently. However, they're probably not in a "whole world search" mode. They're looking at *an* area; if that area isn't where the accident happened, they didn't get anything.
Personally, I'm a bit skeptical, due to the paucity of information about the detection. There's enough in the "Dip****" chain that they might have detected a fire AFTERWARDS and the reports got warped into a false statement of detection of the explosion itself. Plus the potential for detecting sunlight off a plume.

I'm going with prior accident, damage to pressure vessel repaired incorrectly or should have been replaced or reinstalled incorrectly. The Russians reputation for lousy maintence and air crashes is monumental, regardless of aircrafts last checkup in Ireland.
me too....I was skeptical.
Good call.
CNN reporting explosive device, allegedly planted by ISIS.
If ISIS is blowing up Russians does that mean ISIS is on our side? In Rambo II and Red Dawn the Russians were the enemy that still so?
CNN reporting explosive device, allegedly planted by ISIS.
The evidence given on CNN was:
1) The claim by ISIS, originally discounted.
2) A satellite "heat signature" at the moment the aircraft disintegrated.
3) ISIS "chatter" confirming plans.
I'm only the messenger, but that was the story at about 5PM EST today.
I heard it was a bomb from a British source before hearing it from CNN, forget who it was as it was during work.Until I hear it from the Egyptian or Russian equivalent of the NTSB I'm not buying it. The last I heard was that no traces of explosive residue had been found. CNN will say anything for ratings. Our news services are under no obligation what so ever to tell the truth, and that comes from a judge's ruling for Fox.
I already provided one perfectly rational non bomb scenario for the heat signature.
That ISIS claims it is a natural and the chatter expected as it makes a great recruiting opportunity.

The U.K. Media has the same interests and owners as the US outside the BBC, some of their stuff is as bad as ours. Like I said, Putin has no reason to withhold the information, if there's a bomb involved, the information would be forthcoming from him or official channels, especially since Egypt is running the investigation and they could use that to gain support in their problems with ISIS.
Here's a source that you will like then:

Actually I do like it as there is no sensationalism or editorializing involved just reporting, and when you read it it's completely hedged with 'may' and there is no definitive statement, or mention of evidence. This is the problem with 24/7 media outlets, they always have to say something, and they have to change what they say a bit and add new words to keep people watching and clicking. The primary constituent of the Internet economy is 'click bait' and so far everything I have seen coming out saying 'bomb' is nothing more than click bait filled with speculation and no solid information.
The fourth estate has been coopted into the corporate culture of profit über alles. Something like this, when word comes from Russian or Egyptian state sources, then I will believe it's a bomb. The British angle I understand, even though the Russians aren't Brits, they are Christian Europeans with the same aristocracy, British politicians could use Russian martyrs to their own political aspirations in their own internal issues with ISIS like Bush used WMDs in Iraq.
I agree with aljezerra, direct and to the point, no hysterics and very much like the BBC. Excellent coverage. of course there are those who will say" ya can't trust them Muslim fellers! Better watch em." Sort of like the idiots who said the pope would run the country if Kennedy was elected.
Henning, what rock have you crawled from under?

BTW, AJZ is using the same sources as the others.
I do find it a little odd that a person who doesn't cite their sources has issues with the sources that are cited.
