OK... so you think it was terrorists - but they screwed up?
Flying at night has its own set of challenges that can only be mitigated by experience. Once the terrs had control of the plane, if anything went wrong, their training would have been quickly stretched. Trying to evade radar, flying west probably aggravated that problem.
While I feel bad for the passengers who were going to be killed in any event, I would have loved to have looked into the cockpit as the fuel state declined with no hope of landing and see that realization that they had been set up by their masters.
