The clock offset and sampling rate set up an ideal race condition, which resulted in the error that caused all of the computers to fail out.
One problem with "it's so one off, it'll never happen" is, with enough flights, it will inevitably happen.
Thankfully, the safety pilot justified their duties by catching what got overloooked and was key to understanding what was going on.
Concerning is, with dual engine failure, the recorders lose power. So, get surprised by an event in Iceland, lose all recorders really doesn't sound like a grand idea. There should be some standby power to them and their inputs for at least long enough for the RAT and/or APU to come online and provide power.
This one could never be properly conveyed in "Seconds from Disaster", it could only be well covered in milliseconds from disaster!

@Linguaholic23 your example reminds me of an automobile insurance company argument for denying a claim.
"The accident is half your fault, as if you had only stayed home, he accident would have never happened."
Interestingly, the courts eventually dismissed that nonsensical claim.
The tire was chopped by the Continental aircraft's engine cowl fragment, tire fragment impact caused fuel tank #5 to rupture. The fuel from tank #5 then flowed into engines 1 &2, producing asymmetric thrust that began at V1, the fuel igniting appearing to ignite in the damaged landing gear's well.
The quantity of fuel isn't exceptionally relevant, post V1, aborting takeoff is unsafe with that aircraft. One can debate until proton decay if the tank would've remained patent if it was filled to 75%. Given that 5 out of 6 prior tire failures resulted in tank ruptures, one being a severe rupture, the amount of fuel isn't exceptionally relevant, especially given one side of the aircraft being plumb out of engines. Being 810 kg overweight was relevant, given the loss of thrust and damage, once past V1, the flight was doomed.

There is one instrument system that I'll rarely trust, my organic sensory system. I've been fooled once by a false horizon, once fooled, twice shy.
The Captain got an "this is odd" moment, which swiftly turned into "I'm about to become a submarine captain" moment, reacted properly and recovered. In some instances, the proper reaction was delayed by continued analysis, resulting in a lesson written in blood, rather than elevated blood pressure and pulse.
To err is human, what one does once one realizes the error reveals the quality of the person.
In this case, recovery, uneventful flight, brushing it under the rug by filing a detailed, honest report for all to eventually learn from. That reveals a top notch person in my book.
Because, three words have gotten me out many troublesome resultant situations, "I fucked up". Lying by omission or commission only reveals someone unworthy of any trust or position of trust. Admitting to an error, documenting it and thereby training others to avoid that error marks one as worthy of a position of trust.

I'm more than familiar with the phenomenon, for me, it's accompanied with a hovering sensation in a situation where hovering is impossible and late symptoms is an urge to void, absent anything to void.
In a crew situation, I learned to ask my crew to cover me as I "reset my mental chips after having my mind blown".
Alone, it's a challenge, but first and always ensure I'm not about to select an action that'll be deleterious to going back to a stable situation. Once that's ascertained, take a deep mental breath and step back and while examining something that has nothing whatsoever to confusion, such as a cabin pressure reading or engine efficiency reading, go back to mental square one and evaluate where, what and desired goal.
The effect is basically, like looking out of the windscreen to view a runway and instead are treated to a low altitude view of the moon.
And landing an aircraft on the moon is an exercise in impossibility, no lift or air to feed the cabin compressors, let alone the engines and provide lift.
Essentially, one develops control loops and something happens that's arriving at the moon disruption happens and the mind, losing its reference loops goes gonzo in trying to get a grip unguided.
Hence, the distraction trick and taking a mental step back and an "ignore the mind blown event and see where we are and what's needed and stabilize that approach first".
Because, waking up dead is really, really hard on one's weekend plans.

Usually, in fixed wing aircraft, an emergency is something one can first take time out to wind their watch. This was more like rotary wing, where split second correct responses are critical.
Which typically only occur at low altitude in both cases. Makes sense, as one cannot crash into the air, but one can crash into the ground or water.
Many years ago, I got fooled briefly by a false horizon. Instruments conflicted with my vision and common sense prevailed and I relied on instruments and halted a hard climb before there was a problem.
To this day, I'll trust instruments over my senses, save if oh, the great wide world is about to smack me in the face and instruments say otherwise, then I'll go for getting the world out of my view and sky prominent in my view, then figure out whatinhell is wrong with my otherwise more reliable instruments.

The water injection system is a fascinating design.
Most consider water the enemy of fire and rightfully so, but properly harnessed, it becomes a benefit, as with the engine, cooling combustion chamber temperatures and providing additional mass to be ejected by the engine, providing thrust.
First capitalized upon by the V2 rocket, which burned ethanol at 85%, the remainder, added water, lest the combustion chamber burn through and providing steam assistance in cooling the engine and ejecting additional mass.
This flight, well, buzzing dense residential neighborhoods, looking at a mountain, all near stall speed the entire time, yeah, that's a white knuckle experience. It's a wonder that the crew still has fingers!
There's also a chance that the engineer tried to toggle the water injection system. Rapid transits tend to get ignored, even on aged systems.
Overall, bad-assed airmanship! No balls of steel there, those are solid cast diamonds all around.

First, before I'd run out and play in that traffic, I'd grab the map and figure out the general bearing of the ridge, gaps and how far the ridge extends for.
Losing visual reference and lift source, begin compass and altitude loss guided serpentine course and choose an altitude of safe egress, hopeully it'd be in the right direction to not taste the mountain. Go 30 -45 degree relative to what inertial course at loss of reference view would bring me and that relative magnetic couse is the way to hopefully egress.
Call it the Helen Kellar maneuver.
As an instructor, unless I was comfortable in entering those conditions with my entire family, I'd not allow a student that degree of risk. There are a lo of less negatively loaded dice to choose from!
A GPS map device in the instructor's lap would also mitigate the exceptional risk.
But then, I have gotten lost ib the woods once. After, I learned how to navigate on time traveled, bearing and sparse observations of landmarks using a map and compass only. And can accurately call out a ten digit grid accurately.

One protective system fails, due to out of scope contamination, turns aircraft suicidal.
Because, that aircraft did a whole hell of a lot to actively try to crash itself.
There's a reason I never griped that airline pilots receive rather generous compensation, this is a classic example of why.
Hopefully, they also redesigned the filters, so that bypass isn't possible when something fouls it.
When designing a protective system, always assume that the worst of the worst conditions are exceeded in ways you've not considered and plan for that. As an example, the water separator gets supersaturated and fails, plan for that and a fuel leak and fire, while still pumping. Basically, if it clogs, it shuts down and refuses to pump.
Otherwise, one gets a bunch of mysteries that garner a shoulder shrug and ends up with a suicidal aircraft.
Better to perspire on not fueling than to have a pilot trying to land an aircraft that's seriously bent on its way down.
Damned fine job though, the flight crew took that crap muffin out of the flames and made a flambe! I'll take a busted ankle over being spare parts any day.

@TheLukaszpg yep, your mother certainly was, while entertaining the US seventh fleet.
Still, reviews have it that you give better head than she did.
And yeah, I'd say it right to your face. Then, wrap my cane around your head.
But, it is nice to hear back from the poster child for their local abortion clinic.
Shelly, thanks for the feedback and apologies for the ugliness. I've worked a number of emergencies, to put it mildly and been in the midst of some as well, being military EMS. Watching the video was hard, it had to be triple tough to have lived through it, watched it and commented.
Even at age 62, I'm learning from some Moms!
And having handled many 737's back during the Ice Age, yeah, risk busted feet vs inferno, no brainer.
Notice injury much later, yeah, got that tee shirt. Indeed, part of why I need a cane now.
Although, I'd probably consider walking to my destination after yet another runway incursion... ;)
Most of my flights being trans-Atlantic. Kind of a tough walk, but I'm stubborn enough.
I'll just get my coat...

@tomtech1537 there's an old joke in research. Torture P sufficiently, it'll agree with whatever results you want. In this case, torturing algorithms and datapoints into submission is basically making up one's own facts.
Still, the University of Liverpool is working on examining WSPR to see if it could achieve the desired results, results are expected in around six months from now.
Given the time frames involved since its disappearance and some major components of the missing aircraft being found, I suspect it's rather unlikely that the aircraft is about to crash anytime soon. So, patience as research continues is warranted.
As for one question in the description, "how can one of the largest aircraft...disappear", big world, planes are tiny in comparison and the pilot evaded radar and was far off course.
As for families and hope, I'll suggest to you that no feeling human wants to be the no good SOB to tell a kid that mommy or daddy isn't coming home. That some will generate false hope and generate hysteria with their claims, well, if there's a hell, I'm sure they'll get a special room there.
