I'm thinking a test run, and instead of commandeering the plane, they'll just blow it up.

Perhaps. It seems to me it would be much easier to take a plane down with a shoulder launched missile or even a lucky RPG shot from the airport perimeter. Less complex, fewer people involved, no airport screening. There would be no problem getting the hardware into the country and the user could possibly get away without being caught. It would have the same effect and it would be impossible to patrol all of the industrial parks and public roads around the nation's airports. The feds posted a warning about the possibility of this last year.
