One notable change is: reinforced cockpit doors that can't be forced open from the outside easily. Good luck hijacking with that.
But another notable change is that plane crews and passengers all understand now that plane hijacking is a life or death situation, and would fight hijackers to the bitter end.
Which is what happened on the very day of 9/11, on Flight 93.
With reinforced doors - pilots still come out to use the restroom. Flight attendants usually just block the aisle. People will fight back in the case of knives. But how much fighting back dk you think is going to happen if people have guns?
How long do you think it’s going to be before a pilot opens the door if a hijacker starts shooting people?
Airport security is by far not just in America with the only exception in my experience is that other airports don’t make you take your shoes off and some allow liquids in carryon
If people think the plane is about to be flown into a skyscraper, I'm not sure a gun will stop them. There are hundreds of people on a plane and at most twenty rounds in a gun. The math isn't in the terrorist's favor.
There also isn't room to get away from angry passengers. They're probably going to overwhelm terrorists with guns relatively quickly.
I don’t believe I’m making up this scenario. But here I go..
I would book a first class flight in the first seat in front of the plane. Make all of the first class passenger - fewer of them, probably wealthier business travelers who don’t think they are Rambo - move to the back of the cabin.
The aisle would be the perfect kill zone. I watched a documentary and they said SWAT training for taking over a plane from terrorist they know that whoever goes in first is likely to get shot.
