If this incident caused any issue, all of you would be saying "THEY LET A CHILD IN THE CONROL ROOM?! OMG how unprofessional!" There are reasons they have specific rules in place. Having ANY distracts in the traffic control room is highly dangerous. It is a job that takes complete concentration and readiness. This was a horrible lack of judgement and he deserves to be fired for taking his job so lightly. I only want trained professionals in control of my flight, and if you disagree, well, you deserve whatever misfortune might occur.
