Given the search and screening procedures now used, it is just a matter of time until something like this becomes a success.
The answer, of course, is not a more "detailed" search - or everybody sitting with their hands in their laps for an hour before landing. Nor can explosive "sniffers" be installed everywhere.
The answer is to profile individuals and prevent them from getting anywhere near an airplane in the first place. This could have been done here - except for the combination of incompetence (not matching existing records) and Al Qaeda's "conditioning" the screeners to accept certain behaviors (setting it up where the lack of a passport was an accepted behavior).
This is asymmetrical warfare at it's finest and unless we go after and kill the heads of the snakes we will forever be bogged down in wrestling with individual snake scales and cleaning up the shit and blood when they succeed.
In the meantime, Political Correctness, complacency, and outright incompetence will continue to take their bloody tolls. We will slowly be strangled in our responses, paralyzed in our actions, and ground to an economic and defensive halt.

The Twin Towers went down and now the airline industry will come down. Terrorists are winning through perseverance while BO bows, writes letters, apologizes and golfs. Profiling is the only way to stop this, as you said.
