After an investigation, it was found that this was due to mud wasps making a nest inside the pitot tubes. The pilots were able to return to Brisbane.
Was watching this with a friend, when my roommate came in quietly, standing there with his weird tasting tea, 14:50 _"They had everything there except what caused the accident. It had disappeared, as if by magic."_ Guy then just blurps out. _"It's Ice, Ice downed the plane. Great mystery."_ Then he walks out, slurping. Need to keep my door closed I think lol.
Outstanding research job, as I was listening making the tubes flat with surface popped up in my mind, as did making the tubes of Aluminum which would have transferred the heat inside the exchanger up to the fuel contact point. What I did not know was if the tube extensions were put there for a reason not disclosed. Soooo glad the problem is fixed. Was fun trying to guess along with the video ... sort of a 'I've got a secret' mindset. Thank you.
Yeah. There is a long history of exchangers in the process industry. Never have I ever seen a shell and tube heat exchanger designed where the tubes AREN'T flush with the plate.
@@MrJr1976 Interesting. So I wonder why the tube extensions? Perhaps a simple cheaper design because it eliminated some machining process in its manufacture? But ... if so why not just make the tubes shorter in the 1st place. Extra material = extra cost in volume manufacturing so wonder what the process sheet looked like and what was in the engineering mindset. Rhetorical of course. Would have to be in the company and have an engineering manager open to discussing the matter... not likely.
You ever tried watching this series on satellite TV while riding the plane? I especially enjoyed the episode where there was an unresolved 737 sudden uncommanded rudder pitchover without a resolution. I looked at my inflight emergency card and noted I was riding the same model =)). Turned a mundane flight to an exhilarating one.
Planes being flown by computer? With as much trouble as computers have, I sure don't want to let a computer fly the plane!! I'm so fascinated by these huge planes being able to fly and more fascinated at how these investigators can find out why a plane crashes even when there's not much to go on! Just amazing!!
A friend of mine who is involved in aviation has said that eventually only computers will fly the plane, no more pilots. If this does happen I know I will never fly again. It's hard enough for me to get on a plane now with 3 skilled pilots, but to get on one with only a computer???? Nope, nope nope.
@@kathymcmahon5308 I stopped flying because I don't want to be sexually molested every time I want to get on a plane. Geesh, they can at least take me out to dinner first!! But, kidding aside, computers are just as fallible as a human but in a different way. The real reason for computer pilots is they don't have to be paid!
So something that disappears. They ruled out temperature . . . because temperature when they examine the plane is not the temperature at the event time when the plane experienced a failure, as the cause of waxing of the fuel. But is there some other aspect of the plane that is affected by temperature that involves the fuel delivery system? Expansion or contraction of metals comes to mind or stiffness or flexibility of plastic (which can shatter) or rubber (which can leak or shatter). Materials whether liquid or solid can definitely behave differently at different temperatures and what you see now is not what was happening then. Elusive indeed.
But not just MAYDAY. I've watched others. I use to enjoy going up in a airbus or military flight. Utill I started watching all the programing. But it applys the same for land tranportation too. Here in the U.S. aand around the world. There are ALOT of Ignorate drivers out there. To put it nicely. ALOT !!!
A small change in one state of a deterministic nonlinear system can result in large differences in a later state, that is, the Butterfly Effect. Wikipedia.
So long as it is a deterministic effect. It appears to be a definition extended. Non linear is an interesting term. Is a coiled entity non linear? Is an entity linear? Butterfly flight appears to be non linear, but to his search mission it surely is not so. Funny stuff. H. S. Haikawa? on origin of words is soooo much clearer.
This is a fascinating one, because you could see how, if the situation had been any less ideal (as far as having such a huge amount of data available), it could very easily have been unsolvable. Perhaps it would have been written off as a fuel line blockage, or something similar. It was this one accident's perfect balance of severity and a good outcome that let the danger be identified.
What I don't understand is why the fuel had water in it to begin with? I'm not a chemist, but I've worked with chemicals for 20 years, and products that I've made or pure products that I've transferred were tested for many things. Including water content. If there's water where there isn't supposed to be, that's considered a contaminant. And with one of things I've made/handled for years being aircraft deicer fluid, I can tell you that standards are extremely high for aviation chemicals. Their fuel would have to fall in line with that no?
I always thought that a huge company such a Boeing would be required by law to do extensive research and develop on these parts which required them to test these parts thoroughly in every conceivable environment possible before such products were accepted to be used to begin with on High Tech Air Craft such as a Boeing 777. Pilot did an amazing job landing that Aircraft. kudos to his crew as well, by the sounds of things they did an outstanding job!
AT 17 MINS 49 SECS - I developed my own theory: Venting for the fuel tanks was restricted, slowing flow. I will see if I am right............... a tiny chance. Just a thought, as I used to be an auto mechanic.
Philip sounds like Hal. His voice isn't consistent with the rest of the people interviewed. Philip should've been put in a different room or something.
No, I diagnose instruments for a living and there in never "whatever is else." There are always maybe 50 elses, and you still have to work through them. It would be nice if I could "rule out" everything but one. If only!
Who else thinks that people should make a movie out of this like the Sully movie? Maybe call it “However Improbable” because of the Sherlock Homes quote “Whatever is left, however improbable, must be the cause…” ?
This channel is designated for that. Not sure which one has proper rights to post them, if any. But considering the channel name, no. They shouldn't have to check for that.
Oh, no. They've installed the HAL 100 on these planes. So it will be the HAL 1000 and then HAL 3000 and then it will spawn it's own race of HAL 9000 super computers to destroy us all!!!!!!!!!!!!!!

@@michaelpcooksey5096 I honestly have no idea. There is no logical reason I can come up with.
@@michaelpcooksey5096 Probably as a safeguard against counterfeit parts.
I wonder why it was designed that way to begin with? Easier manufacturing process? What purpose did the original design serve?
Atleast no one die to find this problem
12:57 The investigator wrote IMPACT backwards so that we, the viewers, could read it. What a guy!
I’ll be flying again in 3 weeks. I’m addicted to these series and I’m sure I’ll be in full blown panic attack soon as we hit V1

Did you make it!?
Forget about the crash videos. There's no possibility that you'll encounter any of those conditions within your lifetime.
This was EXCELLENT. Fascinating and great detective work.
I think it's the first time the interviewee (the pilot) plays his own role inside the actions scenes in the cockpit !
They've gone overboard with the lens flares.

2008: Month long meticulous investigations pinpoint exactly why a plane crashed.
2024: "The plane was a Boeing, case closed."
Jonathan Aris (the narrator) sounds an _awful_ lot like writer/comedian David Mitchell here.
once again, safety features cause more problems then they solve.
Soooo....how did a year of testing lead to a crash?
I always thought that a huge company such a Boeing would be required by law to do extensive research and develop on these parts which required them to test these parts thoroughly in every conceivable environment possible before such products were accepted to be used to begin with on High Tech Air Craft such as a Boeing 777.

😢😢 The passengers and crew are ok right
It was ice in the engine's fuel supply system that starved the engines for fuel.
Why are they testing the LED, and which LED is that?
I believe it’s a typo. I think they wanted to say “what led” to the crash…
Did J.J. Abrams direct this episode? There's blinding lens flares everywhere.
Too many commercials.
QAR - looks like a PCMCIA slot card?! 🤣
bingo and it is.
I was litteraly born when this happened
So, Boeing doesn't take the rap? For once?
Boeing produces only a fraction of the airplane parts in house but of course they do assemble it.
No, I diagnose instruments for a living and there in never "whatever is else." There are always maybe 50 elses, and you still have to work through them. It would be nice if I could "rule out" everything but one. If only!
"Whatever is left". I think was the quote.

"The purpose of the fuel heater, is to heat the fuel up."
