Time to be serious
If we were serious about flight safety, then years ago we would have banned the carriage of cigarettes, cigars etc AND the matches and lighters that accompany them. We would also have banned all flamable liquids from the cabin, & that includes all alcoholic drinks and perfumes and anything you can't prove is just water.
There should be random searches for such items and HUGE penalties (prison) for being caught.
I know it would upset the owners of the shopping malls that we all fly from, but are we serious about safety or do we only care about the retail industry and "security" job-creation industry??
