Not sure what you're talking about here. The reason 911 actually happened was because no one on the plane expected anymore more than a bit of inconvenience (flying to a different destination).

I'd say do nothing. There aren't enough people trying to do this sort of thing to make it worth the effort or expense. Especially since they have to die every time they do it.
