Sounds a little hysterical, similar to the tenor of the news coverage. When you cite "hundreds of thousands" as potentially being put at risk in this situation I envision a legion of kindergartners simultaneously hijacking ARTCC, Approach and tower facilities and providing seperation services. Hell, I've heard kids on frequency before. I was dealing with Omaha approach several years ago late at night talking to a little girl. I could hear dad(?) coaching her when he keyed the mike.
As was pointed out earlier the young man was not providing sequencing, separation or traffic advisorys. He was saying "Cleared for takeoff", "contact approach" and "adios". The people that have far more standing than anyone on this board to be outraged about this, the flight crews, were chuckling about it. Ahhh...it turns out they are actually complicit in this glaring breach of safety...Probably be a good idea to issue emergency revocation of their certificates as well as ruining the kids day and probably the career of the responsible adult. This is silly.
