I propose that the airlines should get both a Sunni and Shiite Muslim cleric to bless their aircrafts. Have them do the blessing in a way that makes it clear that anyone that causes harm to the aircraft: Doesn’t pass Go, Doesn’t collect $200, Doesn’t get their 42 virgins and goes straight to hell.
You’ve got to fight fire with fire and get religion, their religion, on the side of peace.
Heck, start with Virgin Airlines as that should be appropriate.
