A post that has little to do with what i've been posting...
You mean all those posts about where the terrorists will get us with GPS guided bomb-drones? And that as such, GPS will eventually be taken away from us?
Oh wait, you just made another one!
Even if it is a credible threat, that doesn't mean GPS is going to go away, is it? Last I heard, we still have airliners, rental trucks, petrol and fertiliser, as well as (in the US anyway) easy access to fire arms.
