This frightens me.

The current sunspot cycle will hit its maximum somewhere around
the year 2000. ADF and Loran have worked through previous sunspot
maxima when pilots were still proficient with other, more
primitive, navigation devices.

Some of the things I read here make me want to fly only with
pilots who are curmudgeonly enough to learn to do a fix with
a sextant and carry a sextant and tables in their flight bags.
