Agreed. I think that what the security experts fail to recognize is that post-9/11, the mindset changed. Before that, if (as a passenger) your plane was hijacked, chances were good that all it meant was that you were going to be inconvenienced by a side trip to some third-world country. Now - it's unlikely that those hijackers just want a ride somewhere. It makes it a lot less likely that passengers are just going to sit there like sheep and let the hijackers do as they choose - and even if the hijackers are armed, there are a lot more non-terrorists than there are terrorists in the back of the plane.
