I feel like we already have the solution. The reason hijacking a plane is attractive for a terrorist is because you essentially have a precision missile. There’s little security for buses or trains because you can’t do the same thing. If you make the cockpit basically bulletproof and have strict procedures about entering the cockpit during flight, then it’s not nearly as attractive. Those changes were already made after 9/11. Hijacking a plane only allows the hijackers to kill the people on board, which isn’t as useful. Literally eliminate TSA and I think we’re good.
