Perhaps the majority of people here who look upon this change as good either know something I don't or have a more realistic view on the situation today.
I can't control everything, so to some extent there always was and always will be an element of fate involved as to whether there will be a hijacking or not.
I certainly hope not, and I think I'm safe in saying that everyone else hopes not, also.
Time will tell. Perhaps the situation today is better, and I really do think that it is better today than it was before 9/11.
I know that personally, I am flying more than I was even BEFORE 9/11, so that says something...
