I feel no need to explain to YOU. However, in theory, shoe bombs would be thought to be hard to detect. We didn't begin to inspect people's shoes at airports until Richard Reid. This LA plot was shortly after 9-11. Box cutters weren't gonna cut it anymore (ha!)As to the tactics involved, I leave that to the terrorists. They aren't perfect, you know. (Really, they're not, it just seems like they are with the kind of coverage they get...)
What's with the allcaps YOU bit? Did I whiz in your Cheerios or something? I was simply curious how one would go about commandeering a plane with a shoe bomb. "I'll leave that up to the terrorists" ain't much of an answer. The 'use it to blow the cockpit door' is far better, but assumes (a) that they have the skill to blow the door but not hard the plane envelope and (b) they wouldn't get beaten before, during, and after such an effort.
