"Interestingly enough, Kansas (back in the stone age) and more recently the state of New Mexico have managed to be able to ban on board alcohol sales while over the vertical confines of that States airspace."

I worked in Wichita during that "stone age" (no offence taken). I forgot about those days when the State Attorney General would jump out of his plane or train seat to try and make an arrest for serving alcohol. I don't think the airlines or RR every tried to contest it then. They just stopped serving and explained why which did a lot for Kansas PR.
