I have experienced loss of GPS while using it as my primary nav-aid while
flying. Twice it occurred over the ocean while out of sight of land. I
suspected at that time that it was a general outage (it took down my
panel-mount GPS as well as my hand-held back-up), but now suspect that it
was close-in jamming.

I remember the general availability of Russian-made GPS jammers about 15
years ago. I didn't realize that the use of GPS jamming was prevalent.
