I agree with many others who feel that it is hard to say what could have been done differently to stop what happened Tuesday, given that the men had been learning how to fly planes in order to use them as missiles and were willing to die for their "cause".

It amazes me though that known terrorists/ sympathizers used their real names and were known to federal agancies by these names. Maybe that was not the case for all of the terrorists but if they had tickets booked in their real names that should have set a flag off somewhere.
