AOPA is working on this issue. Specifically on using cell phones or PCS
in general aviation aircraft while airborne. What is interesting with
cell phones is, that they can be used in variety of ways on tracking,
locating, etc. If you remember an accident that one of our F-117's was
shot down over former Yugoslavia during the Balkan war.....they plotted
its position using cell phones and the cell phone towers and the rest
was just history. Ground to air missile accepted the coordinates from
the PCS network and found its target. Pilot safely bailed out though.
