My point is this: While all of us probably knew that switching GPS off
was always an option, making it policy gives fuel to the Galileo
proponents.


The policy of switching off navigation aids under certain conditions has
existed since the early 1960's. The only thing "new" is that the law just
enacted adds GPS to other navigation aids, such as VOR. Read up on SCATANA
(also called SCANTANA). If you dig through some of the news releases, a
limited SCATANA was put into effect on 9/11.

SCATANA is not secret. You can read about it in part 245 of USC 32,
