Well, first of all this was a center controller, not a tower
controller. I don't believe that center controllers work alone in the
U.S., if they do I would be surprised. Secondly, their phone system
was offline and their conflict warning system was down... what, no
money for backup systems? Would that happen in the U.S.? I sure hope
not...

Do the airlines have redundant (backup) systems?
