I fail to understand this. How would the passengers and flight crews intervene against armed (with knife) assailants?
The 9/11 hijackings relied on the fact that a "hijacking" was considered to be something like being diverted to Canada/Mexico/Cuba and then being let go. Annoying, but no point in putting your life at risk.
Once the knowledge that the hijackers were doing a suicide run got out the people no longer sat still (see Flight 93).
6 people can't possibly stop all 100 people in the confined space of an airplane with mere knives.
Frankly this is the asinine US view which results in so many shootings because there are just so many guns floating around basically unrestricted
Trip wire between the seats. Instead of those oxygen masks it's a hammer that swings down. Hot iron on the bathroom pull handle.
pfft, now you have hardened cockpit doors that’ll keep you safe if you manage to SE your way into the cockpit (which at least on long haul flights departing from europe hasn’t been super hard IME)
A terror group could just have one of their operatives blow a million dollars on first class flights to achieve some VVIP-status like BA executive premier, then it suddenly becomes really easy to ask for things like seeing the cockpit during takeoff.
Or you could just charter a few large private jets, there wouldn’t be any other passengers to fuck you over and you’d be in charge of the fligut route.
I guess they’d shoot you down faster these days, but to mitigate that you’d just need to depart from a city airport and make sure they let you in the cockpit early on.
I’m absolutely sure there could be a new (single-aircraft) 9/11, and it wouldn’t even be particularly difficult to execute by a group of people that isn’t already under heavy government surveillance.
Machetes on the other hand, that might suck
