If we go the terrorism route. First, you only declare you have done it if you don't plan on doing it again. This could merely be a test run. Determine if something is possible and then hide the evidence of what you have done. Examples, killing an entire load of passengers in flight so a dead plane arrives/crashes at its destination. The damage to the industry would be immense. How its done is from simply vacating the air in the cabin to poisoning them. If not terrorism, who would take a plane that far off course except to possibly steal it or someone on it? That is more far fetched than simple terrorism. I would have preferred it to be a mechanical issue, but that they tracked the plane off course and for so long makes that difficult, unless of course the pilots detected a decompression issue and tried to turn around. Even then they would simply go low and continue on, I cannot for see any reason no one would have raised contact unless they were prevented from doing so.
