"A little more evidence that goes to show how a 9/11 style hijacking could not occur again"
Lucky the door was locked. Bear in mind few airlines (outside the US and UK) have a locked door policy. Fly on most european airlines and you'll still be able to get flight deck vist and jump seats.
A quick browse on airliners.net and you'll see evidence of that! Even people on jumpseats into the US- so dont be so sure it couldn't happen again.
