Anyone here have any ideas on what might have happened here. I fly a lot and its beyond me that this can happen.
Plane sinks at sea. How many times has it happened in world history?
Fake passports? I reckon there are several flights conducted every day on a world basis where at least one passenger has a fake passport.
No-fly lists are ineffective, those resourceful enough to be a major treat are also able to create fake identities.
