This plane was crashed due to passenger interference with the original plan.
There is no evidence but pure speculation to suggest otherwise, and what difference does it make anyway.
Those who start with the assumption that every official story is laced with lies and propaganda need to be taking more meds.
If you don't fix that, you will hurt yourselves. You will join the ranks of the silliest conspiracy nuts on the planet, a trophy now in the possession of the Russians.
They think they know the real truth when in reality, their conspiratorial nature is being used by the government to control their behavior.
While I do not buy the official line about the center fuel tank garbage, I do not believe there is any reason to think that this particular incident happened any differently.
