Default 2-way GPS . . . ?

Excite today carried a piece re. the S. American crash and location of planes over the ocean. It
went on to say that radar can't see beyond about 200 miles (let alone the fact that bending radar
coverage beyond LOS is pretty remarkable in its own right). Some dip**** was quoted that he can be
tracked on his Blackberry and doesn't understand why it can't be done with planes. Testimony to
what the public is led to believe by TV and movies.

The gist of the article was that we already have a great GPS network and that it will be only a
small step ( $35 bill ) to apply it to planes. This was yet another article that holds technology
up to god-like status, with not a hint of how things really operate. Nowhere in it was there
mention of the fact that GPS is a one-way venue and Big Bro can't track anything without
transceivers, whether it be GPS or conventional radar-based squawkers. Am I wrong about this ???
