Well most of the veteran pilots with actual, extremely long term cockpit experience in various different planes and using airports worldwide that I am listening to, are ruling out fuel contamination.

Well since they say so, with zero actual access to any evidence they must be right! We’ll just start coming to you with our aviation questions since you watch experts on video. You have all the answers. No need for an investigation, we’ll just let other pilots who post on YouTube tell us what happened.

You just did the same thing, speculated that it could likely be fuel contamination. It's all speculation at this point and nobody here or anywhere claims that they know the answers.

And yet you take everything you watch on YouTube as gospel and come in like you know better than everyone else, whereas I was simply speculating about one possible cause. There’s a huge difference. Yes I’m speculating too, everyone is at this point, but I don’t feel it necessary to fall back on pointing out experience, whereas you do every other post to try to show why you should be listened to.

The airport also investigated their fuel and found no contamination issues as they also fueled many planes with the same fuel before the 787.

I listened to the investigators at the airport, and other pilots with a great deal of experience, I'd say if I had to listen to anyone, it would be from these very credible sources, but I still am of the mind that the final investigation will lay out the real cause.

Because the airport fuel system is the only possible way to contaminate a fuel tank. Got it. Good to know that all those fuel tanks that I’ve seen contaminated weren’t actually contaminated because the airport fuel system stopped it.

Well, that will come out with the final investigation, but as far as my sources stated, they have ruled out fuel contamination from that fuel tank at that particular airport and that is all I was relaying.

If you have proof of other fuel contamination please post your sources.

Your “sources” don’t have proof of it not being fuel contamination, any more than I have proof it was. That’s why it’s called SPECULATION. Your “sources” ruled out the airport fuel system as being a source of contamination. The ONLY people that can rule anything out are the actual investigators, so unless one of your “sources” is on the investigation, they haven’t ruled anything out.

The fuel on the plane could very well have fuel contamination from some other source as you stated without explaining what other ways fuel can become contaminated, but what I am relaying here is that the airport investigators have ruled out fuel contamination from their tanks at their airport. See the distinction?

Of course, we have no way of knowing if the investigation conducted on that specific fuel, fuel storage system and filter/sensor systems was done properly, who knows? But the probability that their high tech filtering system with sensors failed seems unlikely as per my multiple credible sources.

Now that I have time to consider fuel contamination via water, it may stand to reason that because of the extreme hot temperatures that day, perhaps the filter system could not handle moisture buildup that may have been present due to the high temps, or the investigators didn't look into that part of it. Again, this will all come out in the final report.

And it could have very well not been contaminated.  I would think if it was some type of fuel contamination, it would be a fleet wide problem.  

What kind of fuel contamination would allow them to star up and taxi with no apparent problems.  But contamination so severe to caused engine failure within seconds of lift off.

Maybe someone more educated could enlighten us.  I assume the fuel system has fuel filters DP and fuel pressure indications and warning?

There are many ways a tank could be contaminated that only affected that plane. If they used trucks it could be biocide used to clean the truck that wasn’t cleaned out well, if there was water in previous fuel loads there could be algae growing in the tank that partially blocked the fuel lines, there could have been something left in the fuel tank that blocked the fuel lines. There are any number of ways that fuel could have caused the engines to not produce power.
