You have a Las Vegas mentality: “what are the odds?”
I hope we are never on a plane together. I dislike flying enough as it is.
My odds are about 99.999999% that my flight is NOT going to be hijacked. I can live with those odds.
I also like to make my connecting flights which will be less and less likely if we allow hysterical people to ground aircraft every time 2 or more Arabs board the plane.
