I am not sure about others. But you along with few others are sure approaching that point.
You are putting forward the theory of Foreign Object in engine. So basic ABC of flight, Foreign Object Ingestion by engine happens during the take off phase. In flight it happens due to bird strike or any such phenomenon which it itself is a very violent phenomenon. But if you would have listen to what the pilot said, he didn't mentioned any such event.
Second, your theory of fuel mixture is even more laugh worthy. You might be thinking a flight fuel storage or tank to be like that of your car which anyone can open up and put some sugar or sand to play foul. Or you might have thought that it was done at the refilling tanker level.
Now look at a mirror and think again whether or not you are approaching the point of stupidity or not?
Problem with guys like you is, if it would have been a Russian engine, you would have quick enough to blame the engine. But since it is an American engine, it is hard for guys like you to come to the term that engines can fail even without external factor.
