How did the plotters know that mother and daughter would move to back of plane and then both fall into a deep sleep - so deep they could take the kid without waking her? And the idea that none of the other passengers saw the kid. Yeah that's possbile but the criminals couldn't assume that.
Car crashes mean car sales - GM loves speeders and DUIs and other highway criminals.
While watching, I just figured that he had first put something in her drink or something and then didn't he make a comment later in the movie, that with "power" and "authority" as an Air Marshal, he just showed her into a food trolly, and then move her down to the interior nose of the plane? when it was just he and Jody dodging each other in getting to the bomb area. She does seem to make leaps of logic as to "out play" the Marshall/Hi-Jackinger at his own game. and then she was the first one off the "boarding & Disembarking of aircraft and the driven away from the scene to their destination while everyone else sat around and had to go through hell. A great way to get through the "security" in an international airport these days. It beats the hell or of going from one line, to another line, then to luggage then into another line, where each person looked at your passport, your bags, took one slip of paper each, then waved us to the next line for about an hour, At least she had the car pick her up on the tarmac, and drive them off the runway with her husbands coffin, her daughter, and all her luggage, didn't even go through Customs.
