Marshalls should be on every flight. If not, a new kind of flight attendant should be there...with military training and the ability to physically stop terrorists. Dressed for combat if necessary. (LaraCroft, Flight Attendent)
Since 911, the prime objective has been to keep people using the airlines. Charge airline passengers what a flight actually costs. Too expensive? Then they should explain why railroads have to make a profit, and they don't.
Now we know for sure people have not been flying recently. In the real world, it's more like Hillary Clinton, Flight Attendant.
