Re Engine

I would be interested in someone with Russian language skills translating what is being said between 2:07 and 2:14 in this video. Looking at the pockmarks/scrapes - I assume 95% chance these occurred on ground strike before rolling 180 but just to be sure... There are also rear seats later in the video which have been mentioned previously, one of which seems to show some entry or exit holes - again, may be related to events during disintegration, but maybe not.

Armchair aviatiors

Chucks:

Yes, if we live long enough we all end up in the armchair speculating on the rumor network.

Your first point seems to be there is something wrong with it, and then you go on to say you saw something interesting. I'm confused.

Thanks - nothing to do with the marks then.

In the same video, there was a 3 man crew at time 1:16 that appeared to be taking technical samples from of the interior of the severed tail.
For explosive residue??

FWIW - Not sure who the "military experts" are.

Tailcone attachment | Firebottle dents

Clean Break?
Intruder asked "How do you get such a clean break all the way around that tail cone? Is that seam an engineered weak point?" (#594).

...to which oleostrut (#595) postulated that the original strength is largely in the skin, supported by ribs, frames, etc.

Actually, according to Airbus confidential drawings (thank you Mr google) the whole tailcone subassembly is bolted to the rest of the empennage via attachment lugs at 4 points. None of those large lugs is visible in the crash photos. In TylerMonkey's photo (#581) showing "better detail" of the tailcone front firewall, the location of 1 of the missing lugs would be expected in the top left of the photo - in the position of the triangular hole in the outermost frame.

Origin of dents on firebottle?
oleostrut pointed out (#589) that the suspicious looking dents on the firebottle are beyond what's expected in normal wear & tear. See also TylerMonkey's closeup pic (#598).

Based on the Airbus drawing of the subassembly, unsurprisingly the firebottle has detached from it's original position which would be in the vicinity of the top left of photo in post #581. So, still tethered to it's line/hose it has presumably suffered like the proverbial rag doll during the tailcone's ground impact.

Disclosure: Not an engineer; just one of those pesky hardware technical writers in a former life.

Catering

Having just retired after many years in the business I always felt that whilst passenger bags were screened and accounted for, most flights travelled with unaccompanied baggage namely catering boxes and carts.
On short turnarounds they are lifted from the hold into a high lift truck and on longer turnarounds from the off airport catering facility.
One wonders how efficient the security screening is at somewhere like Sharm.
A small explosive in the rear galley would be catastrophic.

So, not very detailed, and not exactly same aircraft, but the layout of the firewall layout looks very familiar.

Another CVR leak (according to Interfax). In short. "Some strange sounds in last sec before end of tape, but crew doesn't make any distress calls".

Why it's not the Rear Pressure Bulkhead

D) pure interest what is the domestic radiator type structure

That 'radiator' type structure is one of the 2 Horizontal Stab Bay access doors.
The interesting thing is that its designed to be a blowout panel in the event of Rear Pressure Bulkhead blowout. This door is still firmly in the closed position. This indicates that there has not been a significant dump of cabin pressure into the H/S Bay.

Consistent with a mid-air explosion / separation. The CVR / FDR are located in the H/S Bay. If there is a sudden removal of the rear end of the AC then all that will be on the recording is the start of the explosion, up until the CVR becomes electrically detached from the audio system in the front of the AC.

Thanks for this info, the most informative of the past 600 or so posts.
Still waiting for any photos of the HS.

Do both of the access doors function as blowout panels, or just the one that we know didn't open?

"Foreign objects found - TASS sources in Egypt."

There were over 200 people and luggage in the aircraft; of course there were 'foreign objects' onboard.

Dont't think expert can't separate allowed lugage from suspicious parts.
