I've been over this front and back trying to find something about this but maybe I am just blind. http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?&c=ecfr&tpl=/ecfrbrowse/Title14/14tab_02.tpl Can I mount weapons on an airplane? Obviously you would have to avoid the prohibited areas of public airports, but at a private airport with 0 commercial flights it's different. I was thinking a couple AR-10s with the new .308 beta c-mags mounted on an RV-4 would make a mean little fightin' machine (and sexy too!). Why? Do I need a reason? THIS IS AMERICA. Besides, how do I know that zombies won't learn how to fly planes, eh? Or what if a hundred zombies are attacking my house and the best option is to do strafing runs from the air.
