As soon as I saw the title, I thought of the furor when Gingrich and Clinton discovered that the FAA was using vacuum tube computers and radar in the air traffic control system.  <a href="http:&#x2F;&#x2F;govinfo.library.unt.edu&#x2F;npr&#x2F;library&#x2F;clinton.htm" rel="nofollow">http:&#x2F;&#x2F;govinfo.library.unt.edu&#x2F;npr&#x2F;library&#x2F;clinton.htm</a>  The foreign (sole) vacuum tube supplier that Clinton mentioned was Russia.  Oh, the embarrassment!<p>I knew that there were some delays in rolling out the the replacement system, so I did some googling to see when it  actually occurred.  My god, it&#x27;s now.  We are in the middle of it.  The upgrade was responsible for the recent air traffic meltdown.  Please somebody, point out my flawed research skills.  I cant believe this.
