I've always thought that the passengers would most likely have been completely oblivious to what was happening, it was a night flight, and it would not have been until a 4-5 hours later that they would have become aware of what was actually happening.
That is a gooden, and nothing seems too far fetched now.
I suppose their is a possibility that the pilots of the other aircraft where in on the plan too, although it seems from that article that it wouldn't have been necessary
Haven't got one, until that info is verified, but if it's true it points more towards a high jacking, perhaps botched hijacking, than catastrophic failure of the plane in my opinion. It's hard to know what info being banded about is true as communications from all involved seem to be a bit...
Don't think it is too similar personally. For example:
1. It appears different tracking / communication systems were switched off at different times, indicating human intervention. The reason military jets could follow the Helios flight was due to these systems still operating as normal.
2...
