Flightplan (2005)

Plot hole: Gene's plot has far too many holes for it to have had any chance of working in real life. He somehow must get himself assigned to that particular flight (OK, maybe as a flight marshal he could persuade his superiors to assign him to it) - but also hope that the air stewardess Stephanie is also assigned to that flight - something he has no control over. He then needs to push Jodie Foster's husband off a building, hope the corpse is taken to the only morgue in the city with a crooked morgue director, hope the coffin is assigned to the flight he is on. On top of that, he needs to get explosives into a coffin, the combination of which he actually says he doesn't know. He also needs to hope no-one notices the child, the child doesn't make a noise while boarding, there are lots of spare seats on this inaugural flight, and that mother and daughter move to them.

Trivia: The role of Kyle was originally written for a male character, but when Jodie Foster expressed interest, the filmmakers felt she was strong enough to carry the part and cast her instead.

Question: How did the hijackers get Kyle's husband onto the roof, and push him without anyone seeing?
