I personally don't get the joke.
Why can't there be humor found in terrorism and airline security? Comedy has always been used to deal with human tragedies. You guys may want to lighten up, if one can find humor in this situation then so be it.
I personally think it is a joke that our President and Congress are using 9/11 as an excuse for every policy move, explain the recession, increase corporate welfare, justify deficit spending, wanting to re-initiate underground nuclear testing,and pass laws that further restrict our freedoms and privacy. We the American people are allowing this to happen just so we can feel "safe" again? That's a good joke!
