But the sharpest frames in the video do NOT show the RAT and this is counter evidence to the RAT theory.
After hours of reading I conclude that so far nobody has the slightest clue about what happened.
1: ...
2: The RAT story is based on a single unsharp video frame. Earlier frames were much sharper but the RAT could not be seen (although there was a sound).
3. ...
I could be wrong, in that case please link QUALITY evidence so that we can learn something new.
This way thousands of people are wasting countless hours.
I've been sitting on my hands for days now...but please stop linking RAT deployment evidence with some blurry cluster of pixelation, which proves nothing.
This Pprune-forensic audio analysis (and subsequent posts) by Kraftstoffvondesibel, although completely ignored by many it seems, is the only clear proof there was a deployed RAT sound recorded in the young boy's video clip. You may disprove the analysis as much as you like, but referring to blurry video regarding possible RAT deployment or not, is indeed " thousands of people are wasting countless hours "

But thank you for your valuable audio analysis

The RAT being deployed or not, is an essential factor.
But indeed, a lot of noise is being generated by some that continue to simply ignore the professional sound analysis provided already 600+ (surviving) posts ago, without any relevant counter-arguments or proof (other than some low quality video).

(And I don't mind this sound analysis to be proven invalid, but then only with similar professional skills and counter arguments.)

well I stopped reading the referenced article when ...
According to Flightradar24 data, the aircraft ascended to a maximum barometric altitude of just 625 feet\x97around 425 feet above the airport\x92s 200‑foot elevation\x97before descending at approximately 475 feet per minute.

Pretty recently, Indian media was reporting that the forward "CVR" has been recovered. Pure speculation..but one might interpret the use of this incorrect terminology and the continued search for this second 'black box' while the rear EAFR should have been easily recovered from the mostly intact tail-section, as an indication that things aren't going as well as expected regarding FDR/CVR data-extracting (as in rear EAFR lacking the last x crucial seconds, and forward EAFR now essential for recovery of the last x-seconds of area-CVR recordings, thanks to RIPS)

the answer to that was already provided earlier

While reading this post, I was wondering whether the opening just last April and with much bravado (if I might say), of the brand-new, state-of-the-art FDR-lab and CVR-lab in Delhi, would not be an important 'political' factor deciding where the EAFR(s) are going to be processed.
An if they decide to do it locally, they will take their time (I hope) not to screw up their moment de gloire

As has been mentioned more than once in the first thread, do not take the reported crew's experience on face value.

The captain's 22y experience and only 8200hrs was addressed ao. in this post .

For the F/O's 1100 hours, I just searched a few minutes on the internet and found " Kunder attended Paris Air in Vero Beach about 15 years ago, Caressa Bray, assistant to the CEO of Paris Air, said June 13." Although this in itself does not prove anything, I would be cautious referencing the 1100 hours as total experience.

But once these 'toughness' requirements come into play, having a brand new FDR lab, might not be sufficient in case you have to reconstruct the melted data access paths to the core memory modules, that indeed in all likelyhood survived.

in my first reply, I started typing, but then removed, 'one thing missing in the FDR's disaster survivability requirements, is 'politics resistance'. Not implying that in this case, except for some face saving moves, the 'thruth' is in danger.

With 'intact' being the crucial part of these recent posts. It is my understanding that a suitably equipped LAME can simply download the FDR data from an installed EAFR (CVR requires dismounting). So downloading as such, isn't the issue.

However more importantly, as implied by another poster 'patience' is of the essence in this thread ...

I'm pretty sure that the OP of the first quote focused on " global centres of IT hardware ". (oops, I see in the meantime that I'm beaten in speed by a considerable margin)
But even then, if I may borrow part of previous quote:
Those are two drastically different things :
* I believe blindly that the " foremost global centres of IT hardware " can recover each and every bit on my drowned IPhone and would not hesitate for a second to handover my phone
* However, I would not trust and/or handover my damaged EAFR to any of those " centres of IT hardware", even just to look at it, let alone touch it, until it was proven that the centre in question, has all the approvals, certifications, qualifications, track record and whatever. So, moon landings or not, that does not prove anything.

No, no, I was thinking about the FDR data being downloadable from the EAFR through the aircraft's network. Be it with the Maintenance Laptop (which I presume) or any kitchen-grade laptop with a physical ethernet port (which I hope is not the case). But I have no clue on what an appropriate device is for such an operation.

Regarding the QAR, the 787 is or can be equipped with a WQAR, but I hate to type the W, as in Wireless, as the moment I hit the 'enter' button, Starlink interfaces will be devised and engineered on the spot....

Question was asked before a couple of times, but except a few answers like " should be on the loadsheet ", " evidence should be on the CVR ", nothing conclusive was reported.

I can add that a few weeks ago, I saw a video from the local media (don't remember the source and/or link), paying tribute to the 12 crew-members with a short bio/a few pictures of each individual, and it were 2 cockpit crew and 12 cabin crew (with a few very junior/trainee CC's). But that in itself, does not prove anything regarding possible jumpseaters.

referring to a few questions asked in both preceding threads, one word not to be found in this prelim is ___ jumpseat(er)
(so status remains unclear)
