Start your trip .. early! on Euphoria Airlines [brought to you by Rapture Associates]. Yes friends, for your safety, convenience and security - the best of that confiscated Sinsemilla is administered by our jack-booted but ever so friendly er 'camouflage suited' Happy Bunnies.
You're forgetting the people in the targets - unless you want to suggest that people starting working for Euphoria Enterprises in the 'big building that is a nice target'.
What happens when the next plane is a cargo jet? (Of course, then the terrorist will have to learn to "take off" - or sneak aboard and wait for the pilot to take off.)
(I still don't understand bin Laden - hell, if he's got the cash he's rumored to have, he could BUY a 757 to fly into a big building.)
