I like the plan one guy came up with a few years ago to end once and for all Islamo plane bombs and hijackings:
1. All Muslims must take separate flights from general population no exceptions.
2. Flight-plan will be filed and followed to the degree.
3. If plane veers one degree off flight plan, auto-pilot will take over, will be impossible to override whereas plane will fly over the nearest ocean miles from any population and shipping lanes and proceed to blow up.
sounds good to me.
