I finished my airplane defense essay

I keep seeing references to the problems with airport screening and decided it was time to finish my essay on airplane security.  I also added some material to the problems with existing security.  This was inspired by an article I had run across some time ago but never got around incorporating until now.  I now have an answer, but not really a solution, to the concerns over explosives being brought on board.  Read the essay if you are interested in that aspect.

To help get more notice of my thoughts on the subject I also posted a couple links in the comments section of Bruce Schneier’s blog posting about airplane security.
