The only real improvements in security since 9/11 in my mind are that cockpit doors are now reinforced and passengers know to fight back.
Everything else is just a show of force to make people feel better.

Passengers fighting back only works if they know there is a problem and the attackers are in the passenger cabin. Once the attacker is past that door they can ignore them.

US military drones have actual weapons and they are not hacked so that part seems to work well.
