So you can sneak a bomb in your shoe. The only solution is to fly naked. You can't bring anything on board; it all has to be shipped separately on cargo jet.

Now you might say to me, Jeff, don't be ridiculous. At least we can fly in our underwear. But no. If enough C4 to take down a jet could be shoved into a shoe, imagine what could fit into a padded bra. I can see the headline now: Man Arrested at Logan With Explosive Codpiece. Ouch.
