Nope, you could hear the other controllers in the background.
Seriously guys; mountain out of a mole hill.
It stems from that weird subsection of our culture that revels in righteous indignation.
Nothing happened.
Nothing bad COULD have happened.
But OMG, just in case something COULD have happened, OMG OMG OMG there are babies on those airplanes that well, uhh, may have gotten a bad instruction. OMG OMGOMG what if, instead, of clearing an airplane for takeoff under the strict oversight of the controllers, the kid said "Airliner 1119, roll inverted and do a lomcevak!" and and.... if the pilot, unable to think for himself, COMPLIED??
Doooooooooooooooooooooom!
There are thousands of people sitting in front of their 42" LCD displays biting their nails, waiting for the controller to approach the podium and apologize. Then they'll debate back and forth over whether the apology was good enough and decide if any administration action was severe enough.
It's the American Idolization of our culture.
