It seems to me that the most pressing question at the moment is where did they go? And why? If they can find the wife some questions might get answered. If the wife and kids have disappeared too it would seem that the "who" that pirated the plane is confirmed.
Didn’t say where they are. Hope they’re not dead. We don’t know if the pilot is the hijacker, or if the passengers are dead, but anybody who would kill 239 people isn’t above wife-o-cide.
