I thought about it, and remembered some more really glaring plotholes/discrepancies/inconsistencies:-
Halfway through the film, the captain finally believes she's mad, as he's faxed information from the hospital in Berlin where her husband died, showing that the daughter too died there.
A) WHO the hell fabricated that? Was there a doctor in on the plot too? The Stasi? KGB? Sons of the Moon? Holy Christ! and also
B) How did anyone get a fax onto an aircraft in flight??
Then there was the matter of "ransom". She's paid 50 million, an exhorbitant sum, surely less than the price of a new aircraft? It's wired to "her" account, despite the fact that all passengers and crew have been allowed to leave, so there's nothing to lose but the plane (plus her, but they wouldn't care if she died, if she is a terrorist). So again
A) Why didn't they just let her blow up the plane and more to the point
B) can an airline pay ransom? Surely it's up to the government of that airline's country to make the call? And can an airline, as a private body, be seen to be negotiating with terrorists??
Not to mention the kid who said at the end to their parents that she had said all along there was a daughter --- no she bloody didn't!!
And when the passengers all see Jodie with her daugher, the final proof that she wasn't mad, these people, who clapped like lunatics when the air marshall captured her, can only muster a quiet "She never gave up" in response!
I could go on and on, but my head is beginning to hurt...
Inicidentally, just to show I'm not totally biased, the question about the FBI being in Newfoundland when they landed? Well, I would assume that they would be allowed some input even if this wasn't their jurisdiction, if the plane was American --- which it was never established it was: it took off from Berlin and flew to New York. It had an English pilot, so could have been any nationality really. But if it WAS American, that MIGHT account for the FBI being there. Plus 9/11 rules, and all that...
