Things sure have changed. Hijackers/terrorists now MUST deal with passengers. Before 9-11 passengers felt safer if they didn't do anything....that has forever changed.
You bet it has. Everyone who plans on flying should think and decide what to do in case action becomes necessary. We were discussing what would we do if .... and we're not planning a trip anytime soon. Someone pointed out that weapons are everywhere on planes. My youngest son decided his size 13 shoe might make a good weapon.
