"Ha Ha, HiJacking - we haven't had one of those in 20 years"
"We haven't seen a highjacking since like 1991."
All I have to say is these guys are morons - and they were old - adults.
I recall when these happened and at the time I had not even flown once in my life, I was a kid.

http://en.wikipedia.org/wiki/Ethiopian_Airlines_Flight_961
http://en.wikipedia.org/wiki/EgyptAir_Flight_990
http://en.wikipedia.org/wiki/Indian_Airlines_Flight_814
Now, I must say that the last 2 (1 not being a complete highjacking) motivated the 9/11 Suicide Bombers.
I can bet that Osama Bin Laden used the EgyptAir_Flight_990 and the Indian_Airlines_Flight_814 as success stories.
That said, I also think that not all the highjackers on 9/11 knew that they would die.
Bin Laden would not risk having 20 people know that they would be on a mass sucide mission. He knows that criminals crack and rat, even his own muslims, so he only shared it with the 4 murderous pilots.
The other terrorist, I'm sure, were told that these highjackings would be as successful as the Indian_Airlines_Flight_814 where the terrorists escaped in vehicles provided them.
The movie overall was great.
