This says it all...
"The FAA offered scant detail on its investigation and wouldn't reveal the name of the controller or supervisor. Control towers are highly secure areas, although the agency does sometimes give employees permission to bring their children for a tour."
Now that people are complaining, the FAA is suspending the controller, for no reason.
I see nothing wrong with this and it reminds me of the days of "bring your kids to work" day. My dad was a high ranked union rep, for Illinois and it was awesome for me, to go with him to meetings, etc.
I've also been flying for pretty much my entire life...since I was 14. I see nothing wrong with a few instructions being given, to pilots, by a child...especially when dad was right there, to take over at any given second. I remember being aprox 5 years old and a family friend putting me on his lap and letting me fly a 12 passenger Cesna.
If I was one of the pilots, I'd have gotten a kick out of it, too.
