[ARC5] And then there were none

[Robert Eleazer]

I was in charge of GPS at the Pentagon for a while.  GPS uses 24 satellites orbiting at 10,900 NM; they are very hard to get at.  You can lose quite a few GPS satelllites before the system is degraded seriously enough to affect aircraft navigation.  If that happens you will not need navaids because the country will be in the midst of a general thermonuclear war and all non-military aircraft that have not been vaporized will be grounded.

And it is far, far, easier to screw up using an ADF than it is using GPS.  I am sure y'all could tell some stories about that.  Ever hear of the B-24D "Lady Be Good?"
