The goal is not to stop the people in the queue being attacked, its to stop someone boarding a plane with the means to hijack it
They fail gloriously at at that too.
Whenever they get tested the red teams manage to smuggle in everything needed to hijiack a plane plus a kitchen sink.
The few times that terrorists tried to board planes, they made it through security and were caught by other passengers.
That’s what’s changed. Before, a hijacking meant a free trip to south America or Cuba. Now it means you’re likely to die if you don’t stop the hijackers. A planeful of pissed off passengers determined to live are gonna stop a would-be hijacker.
Plus the cockpit doors lock. Which can turn out to be a double-edged sword if the pilot has a breakdown and decides he wants to take everyone else with him.
Yeah, and you don’t need the TSA for that. Just do as they already do: lock the cockpit.
Little known fact: many of the pilots behind those locked doors are armed as well.
The Flight Deck Officer program allows pilots to volunteer to become deputized Air Marshals. They receive training and are issued a badge and a gun.
Well, conceivably those in the cockpit could be manipulated through other threats. Either threats to crash the plane, or threats to hurt the people in the back.
Part of their training includes risk assessment that teaches them to sacrifice individuals if it is in favor of maintaining control of the plane.
They flat out train them to shoot through a hostage someone is holding. That one person’s life isn’t worth sacrificing the lives of hundreds of others on board as well is casualties on the ground.
They had to do something about the plague of people hijacking planes with bottles of water.
IIRC water happens to appear similarly to a lot of explosives on the metric they use for what the composition of items in the scanner is.
Improvements are being made though so soon we may be allowed to take water through unrestricted:
