Did you hear what they said?

NBC: 1 Cessna + 200 lb of fertelizer = Oklahoma bombing.

ABC: 1 small plane + several lb of C4 = Serious destruction

Wow, serious stuff.... But it seems using a Honda Civic + the same
amount of bomb material will be much easier than using a GA plane.
Unless those targets that are un-accessible by cars, such as White
House. That's why we have ADIZ.

It is a tough issue to deal with.... Just like buying a virus
protection software. It will never protect you from the latest virus
attack, no mater how much money you spend, until someone become a
victim.
