2 things- How did no one see the girl get on the plane?
That's just ridiculous, people might be in their own little world, but for not a single person to recall seeing her is the biggest goof of all.
And this is another thing i don't understand, they tell her that her daughter died when the dad did, but how come she wasn't bringing the girls body back with her, why only her husband, where would she have left her daughters body.
Didn't she think to ask that, or didn't the captain wonder that
