Jim... You're right on target with your observation... Beware of reporters 
bearing BULLSHIT... Technically, I've yet to meet a reporter who had any 
reasonable knowledge of technology... Particularly in the areas of 
Electronics and Aviation...

Resistance is futile, but... Impedance is much more complex..!
