It is time for a new airline: Free-for-all air.
No security, take whatever you think you need to defend yourself to make sure the plane gets to its intended destination.
Obviously, no beverage service (and no safety lecture!), and no way for the passengers to reach the pilots. (Seperate entrance for the pilots? Perhaps small wings that allow the pilots to glide to a safe landing?)
Need they mention that they are glad they don’t fly much anymore?
