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. 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 " I'm rather under the impression that many recent discussions are going backwards or h amsterwheeling.

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.)

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.

* only the forward EAFR (Enhanced airborne flight recorder) has an (external) RIPS (Recorder independent power supply) * and this RIPS provides, in addition to the forward EAFR, the cockpit area microphone and the preamplifier for this microphone with 10 minutes of backup power 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) Subjects (links are to this post in the relevant subject page so that this post can be seen in context): CVR Cockpit Area Audio DFDR EAFR RIPS |

Absolutely. This confidence that the EAFR has already been read is misplaced. It\x92s a specialist piece of equipment and probably can\x92t even be downloaded in India. It\x92s most likely on its way to the NTSB, the BEA or the AAIB (UK) for analysis which will be done under strict conditions (for obvious reasons).
An if they decide to do it locally, they will take their time (I hope) not to screw up their moment de gloire Subjects (links are to this post in the relevant subject page so that this post can be seen in context): AAIB (All) EAFR NTSB |

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. Subjects: None |

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.

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.

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....

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).
