I agree, there's nothing wrong with this, the kid wasn't trying to screw anything up, and he DID have someone that does this every day telling him what to do.
I was on a C-17 flyin to AK one time, and there was this IDIOT fat kid that started talking to the tower thinking he was on the hot mic! He coulda got some people in BIG trouble, he was just talking nonsense!
It was pretty funny though, they just "asked" him to get out of the cockpit and not come back,lol
