Hey you can't really assume anything with a film like this and with a storyline being so mysterious and suspenseful. I think it is left up to one's imagination where the passengers disappeared too. Personally I think or would like to believe they all survived but in another dimension probarly in the 4 or 5th dimension like with the Bermuda triangle which is very similar to the movie in relation to people disappearing without a trace.
Actually, since items like pacemakers were left behind it's safe to assume at least some of the missing passengers are dead.
I assume that since some passengers who disappeared left behind their pacemakers, they probably died.
